XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

1: Overview and Features

Overview

Description

The standard XLi IEEE 1588 Clock, also referred to as the “XLi”, provides a complete implementation of

a Precise Time Protocol (PTP) “ordinary clock” over a dedicated IEEE 1588 card. The IEEE 1588 card

can be configured to operate as a PTP grandmaster or as a PTP slave.

As a PTP grandmaster, the IEEE 1588 card typically synchronizes PTP slaves on the network to

International Atomic Time (TAI). The XLi IEEE 1588 Clock derives TAI from the Global Positioning

System (GPS). In addition, Symmetricom designed the XLi IEEE 1588 Clock so the user can distribute

Coordinated Universal Time (UTC) or user-entered time over PTP.

As a PTP slave, the IEEE card automatically discovers a PTP master within its subnet/subdomain and

synchronizes to it. The PTP slave in turn, can be configured as the primary reference source for the XLi

IEEE 1588 Clock (the clock synchronizes to the PTP slave).

The XLi’s Time Interval/Event Time (TIET) feature can be used to measure PTP synchronization across

timing networks. For example, to measure a PTP slave’s synchronization to the PTP grandmaster, the

user connects the PPS output of a PTP slave to the XLi IEEE 1588 Clock and configures F110 to display

the time interval between each PPS.

See F130 - Precision Time Protocol Status (page 116) and F131 - Precision Time Protocol Network

Config (page 119) for more information.

GPS C/A Receiver (87-8028-2)

Introduction

The GPS C/A Receiver acts as a Stratum 0 timing reference source to the XLi. It tracks up to 12 L1 GPS

satellites, decodes their signals for time and position, and feeds this data to the XLi through the internal

backplane. When available and enabled, the GPS C/A Receiver card provides superior time and

frequency accuracy on the XLi (See “System Time & Frequency Accuracy” on page 10 ). The GPS C/A

Receiver card comes with an L1 GPS antenna, cabling, and mounting hardware unless otherwise

specified at the time of purchase.

The GPS C/A Receiver uses a TRAIM (Time Receiver Autonomous Integrity Monitoring) algorithm to

monitor the integrity of the receiver’s timing solution. Using redundant measurements, TRAIM detects

and quarantines anomalous GPS signals, independent of the GPS health ephemeris data. The

quarantined signal is excluded from the timing solution for 12 hours before it is requalified for inclusion in

the timing solution.

See “Installing the GPS Antenna” on page 15 for information on selecting an antenna site, mounting the

antenna, and signal strength requirements.

The GPS C/A Receiver card can be managed and configured using F53 – GPS Operation

Mode (page 58) and F119 – GPS Receiver Configuration (page 110).

F8 - Continuous Time Once-per-Second

The function F8 commands and outputs are available only on the command line interface (through the

serial and network ports). They are not available through the keypad display or web interfaces.

Function F8 outputs the time-of-year once per second, conditionally followed by a time quality character.

F8 is affected by the following functions:

•

F2 – 12/24 Hour Format (page 39)

XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

•

F5 – Time-Quality Setup (page 43)

F11 - Time Output Format (page 50)

F69 – Time Mode (page 65)

The Format of the F8 Output String

The factory setting for the output string format is as follows:

where:

<SOH> = ASCII Start-of-Heading character

<CR>

<LF>

DDD

= ASCII Carriage Return character

= ASCII Line Feed character

= day-of-year.

= hours.

= minutes.

= seconds.

mmm

= milliseconds.

= colon separator.

= time quality character (see the following table)

The time quality character, "Q", is one of the following characters:

SPACE = Time error is less than time quality flag 1's threshold

= Time error has exceeded time quality flag 1's threshold

= Time error has exceeded time quality flag 2's threshold

= Time error has exceeded time quality flag 3's threshold

= Time error has exceeded time quality flag 4's threshold

or a reference source is unavailable

The time quality characters can not be modified.

Use F11 - Time Output Format (page 50) to change the format of the F8 output string.

Use F5 – Time-Quality Setup (page 43) to set the four time quality thresholds.

XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

While Synchronizing to a Reference Source

Following startup, the user should avoid using F8 outputs until the XLi has acquired and locked to a

timing reference source such as GPS PRI (when F131 is set to PTP MASTER) or the IEEE 1588 card

(when F131 is set to PTP SLAVE PRIMARY).

F8’s output appears similar to the following example while the XLi locks and synchronizes to a reference:

001:00:13:45*

001:00:13:46?

...

001:00:14:05?

001:00:13:44

001:00:13:59

...

001:00:14:05

322:17:59:34

322:17:59:35

When the time quality characters clear, and the time-of-year synchronizes to the reference source time,

the F8 output string should be considered accurate and reliable.

After Loosing a Reference Source

If the system clock comes unlocked from the reference source (no reference sources available), F8

continues generating time-of-year information based on the synchronized time. Gradually, as the

estimated worst case time error (“F13 – Time Error”, page 52) accumulates and exceeds each time

quality threshold (“F5 – Time-Quality Setup”, page 43), F8 appends the appropriate time quality

character to the time-of-year string. This progression appears similar to the following example:

322:18:02:31

322:18:02:32.

322:18:02:33*

322:18:02:34*

Command Line

For example, to initiate Continuous Time once-per-second, enter:

F8<CR>

The XLi replies:

199:11:19:30<CR><LF>

199:11:19:31<CR><LF>

199:11:19:32<CR><LF>

To stop F8 Continuous Time Once-Per-Second, press Ctrl-C on your keyboard.

997-01510-03, Rev. C, 12/12/2006

F9 - Time On Request

This function is available through the command line interface only. It is not available from the keypad.

Use function F9 to record the exact time the XLi receives a request from the user.

Enter the command "F9<CR>" to prepare the XLi for the user's request. At the desired moment, send

the request to the XLi by entering an upper case "T". The XLi saves the current time-of-day, accurate to

within 1μS, to a buffer, and then outputs it to the command line interface. The XLi continues to provide

the time-of-day each time it receives a "T" until F9 is cancelled. To cancel F9, enter Ctrl-C on your

keyboard. The command line disregards all input other than SHIFT-T and Ctrl-C.

The time-of-day output is only available on the network or serial port used to give the F9 command.

F9’s factory set output string is as follows:

where:

<SOH> = ASCII Start-of-Heading character

<CR>

<LF>

YYYY

DDD

= ASCII Carriage Return character

= ASCII Line Feed character

= year

= day-of-year.

= hours.

= minutes.

= seconds.

mmm

= milliseconds.

= colon separator.

= time quality character (see the following table)

The time quality character, "Q", is one of the following characters:

SPACE = Time error is less than time quality flag 1's threshold

= Time error has exceeded time quality flag 1's threshold

= Time error has exceeded time quality flag 2's threshold

= Time error has exceeded time quality flag 3's threshold

= Time error has exceeded time quality flag 4's threshold, or a reference source is unavailable

For example, to prepare Time on Request, enter:

XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

F9<CR>

Then, to request the current time, enter SHIFT-T on your keyboard. ("T" does not appear). XLi responds:

To exit F9 press Ctrl-C on your keyboard.

F11 - Time Output Format

Use function F11 to change the format of the F8 and F9 time output strings. The factory setting for F11

format is null, which reinstates the factory default time output formats for F8 and F9:

(for F8)

(for F9)

To display the default format for F11, enter:

F11

F11 responds:

F11 DDD:HH:MM:SS.mmmQ

where:

<SOH> = ASCII Start-of-Heading character

<CR>

<LF>

DDD

= ASCII Carriage Return character

= ASCII Line Feed character

= day-of-year.

= hours.

= minutes.

= seconds.

mmm

= milliseconds.

= colon separator.

= time quality character (see the following table)

XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

The time quality character, "Q", is one of the following characters:

SPACE = Time error is less than time quality flag 1's threshold

= Time error has exceeded time quality flag 1's threshold

= Time error has exceeded time quality flag 2's threshold

= Time error has exceeded time quality flag 3's threshold

= Time error has exceeded time quality flag 4's threshold, or a reference source is unavailable

Note: F8 does not display milliseconds, regardless of the format defined in F11.

Suppress the “DDD”, “HH”, “MM”, “SS”, “mmm”, and “Q” segments of F11 by placing an “X” (Shift-X) in

the leading position of any segment, followed by any placeholder characters, and the following

separator. For example, to suppress “DDD”, enter:

F11 X--:

To see the resulting change to F11, enter:

F11

F11, with “DDD” suppressed, responds:

F11 XDD:HH:MM:SS.mmmQ

With “DDD” suppressed, the output of F8 would look like this example:

:16:23:32

Ending a format string early (no “:” or “.” separator at the end) with a carriage return, enables the

remaining un-typed characters. This makes it easy to restore the default F11 formatting.

To return F11 to its default format, enter:

F11 D

To display the restored defaults, enter “F11” again. F11 responds:

F11 DDD:HH:MM:SS.mmmQ

The “DDD”, “HH”, “MM”, “SS”, “mmm”, and “Q” segments can not be replaced with characters, they can

only be suppressed.

The “:” and “.” separators can be replaced with ASCII characters or suppressed using “X”. For example,

to replace the separators with characters, enter:

F11 ---D--H--M--S

When you check the results by entering “F11”, F11 responds:

XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

F11 DDDDHHHMMMSSSmmmQ

With the new formatting, F8 displays:

128D16H41M27*

And F9 displays:

365D16H45M22S680*

F13 – Time Error

Use function F13 to request the estimated worst-case time error due to oscillator drift during periods of

unlock from a reference source. See “System Time & Frequency Accuracy” on page 10 for more

information on time error for different reference sources. Time error begins to accumulate when the

receiver loses lock to a reference source. The XLi calculates the worst-case time error based on the

stability of system clock’s oscillator type, and the time elapsed since loss of lock.

Command Line

The Command line interface will report time error when it receives the following string:

F13<CR>

The XLi responds:

F13<S><ERROR><CR><LF>

where:

F13

<S>

= ASCII string for function F13

= ASCII space character

<ERROR> = calculated worst-case error in seconds

<CR>

<LF>

= carriage return character

= line feed

For example, to display the time error, enter:

F13<CR>

XLi responds (example):

F13 TIME ERROR -0.002932863<CR><LF>

F51 – GPS Antenna Cable Delay

Use function F51 to display or configure the GPS antenna cable delay. Setting a positive value for F51

compensates for the time the signal takes to travel the length of the cable from the GPS antenna to the

receiver. When multiple GPS receivers are installed, a separate value can be set for each unique

receiver. The factory setting for F51 is +60 ns, which corresponds to the 50-foot (15.24-meter) long RG-

XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

59 GPS antenna cable supplied with the XLi. If the GPS antenna is connected using a different antenna

length, calculate the new value using the multiple given below and adjust the value of F51. If using an

optional Down/Up Converter, consult that product’s documentation for directions on setting the correct

cable delay.

F51 Guidelines:

•

For RG-59: multiply the cable length by 1.24 ns/ft. to get the value for F51.

For RG-58: multiply the cable length by 1.4 ns/ft. to get the value for F51.

Don’t use function F51 to adjust the XLi’s timing outputs; use F52 Distribution Cable Delay

instead.

Command Line

Use the following format to display the current Antenna Cable Delay setting:

F51<S>B<N><CR>

The XLi responds using the following format:

F51<S>B<N><SEP><SIGN><DELAY>ns<CR><LF>

F52 – Distribution Cable Delay

Use function F52 to display or set the distribution cable delay for the time code and 1 PPS outputs. F52

compensates for the signal’s travel time from the XLi to its point of use. The distribution cable delay

_{applies uniformly to all output ports. The as-shipped factory setting is +0 ns. The rang}1_{e of possible}

values is +999,999 ns to –999,999 ns. Positive values advance the timing signals, while negative values

retard them.

To calculate what the setting should be, multiply the delay/foot by the length of the cable in feet. The

typical delays for the following cable types are:

•

RG-58 – approximately 1.4 ns/foot

RG-59 – approximately 1.24 ns/foot

F53 – GPS Operation Mode

The GPS C/A Receiver (87-8028-2) has two modes:

•

Select “Dynamic Mode” if the position of the receiver is subject to frequent change, or if it is in

continuous motion. For example, use Dynamic Mode when the XLi is used in mobile vehicles

such as ships, land vehicles, or aircraft. With Dynamic Mode selected, the receiver updates the

position information repeatedly to arrive at the best time calculations for a mobile environment.

•

Select “Time Mode” if the receiver used in a static environment such as a server room. With Time

Mode, the receiver averages the position data over time to determine the antenna position and

calculate the time precisely and accurately.

F60 – GPS Receiver Satellite List

Use function F60 to display the identification number and signal strength of tracked or current satellites.

‘Tracked’ means a satellite’s signal is being received and interpreted by the receiver (or that the XLi has

GPS data that suggests this satellite should be visible to the antenna).

GPS satellite are grouped into the following categories:

•

Tracked: the XLi is receiving the GPS signal, but isn’t using it to calculate time and position.

Current: the XLi is using the satellite’s GPS signal to calculate time and position.

Bad: the GPS satellite is transmitting information that it has been removed from service.

Rejected: the XLi M12 receiver’s TRAIM feature has detected anomalous signals from this

satellite and has quarantined it from the timing solution for 12 hours.

GPS satellite signal strengths are reported in units of dBW. Signals below -170 dBW (e.g., -171 dBW)

are not usable by the GPS receiver. See “GPS Signal Strength Requirements” on page 17.

If multiple GPS receivers are installed in the XLi, F60 identifies the GPS receiver by the option bay

number in which it is located. For a diagram of option bay numbers, see “F118 – Option Board

Configuration” on page 108 .

If you’re using the keypad/display interface, use the UP/DOWN ARROWs to scroll through the list of

satellites.

F66 – Daylight Saving Time (DST) Mode

Use function F66 to enable or disable Daylight Saving Time (DST), and to schedule when Local time

enters and leaves DST. The factory setting for F66 is Manual (i.e., DST On). The hour for entering/

leaving DST is given in the 24-hour format. Entering/leaving DST can be scheduled for any hour of the

day, any day of the year. However, transitions scheduled within 24 hours of the beginning/end of the year

may not occur at the desired time. This function also works for locations in the southern hemisphere,

where DST spans the new year.

Command Line

To display the current status of F66, enter a command using the following format:

F66<CR>

XLi responds using the following format:

F66<S><STATE><ENTER/EXIT><CR>

where:

= ASCII character F

= function number

<S>

= ASCII space character one or more.

= Off or Manual.

<STATE>

<ENTER/EXIT> = If <STATE> is Manual, <ENTER/EXIT> are the dates it enters and exits DST.

<CR>

<LF>

= carriage return character.

= line feed character.

For example, to disable DST, enter:

F66 Off<CR>

XLi responds:

OK<CR><LF>

To enable DST and set the DST entry and exit times, use the following format:

F66 MANUAL<INHOUR><SEP><INWEEK><SEP><INDAY><SEP><INMONTH><OUTHOUR>

XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

where:

<SEP>

= time to enter DST in 24-hour format.

= one or more separator characters, either space comma or tab characters. For output strings

this will be a single space character.

<INDAY>

= which week to enter DST, 1, 2, 3, 4 or 0 (for last).

= day of week to enter DST, 1 through 7 where Sunday is 1.

<INMONTH> = month to enter DST, 1 through 12 where 1 is January.

<OUTHOUR> = hour to exit DST, in 24 hour format.

<OUTWEEK> = which week to exit DST, 1, 2, 3, 4 or 0 (for last).

= day in to exit DST, 1 through 7 where Sunday is 1.

<OUTMONTH> = month to exit DST, 1 through 12 where 1 is January

<CR>

<LF>

= carriage return character.

= line feed character.

For example, enter:

F66 MANUAL 02 1 1 04 02 0 1 10

Meaning:

•

Manual settings are in effect.

The entry time is 02 a.m., week 1 (first), day 1 (Sunday), month 4 (April)

The exit time is 02 a.m., week 0 (last), day 1 (Sunday), month 10 (October).

To leave the value of any item unchanged, insert a semicolon in its place. For example, to change the

week DST begins, enter:

F66 MANUAL ; 0 ; ; ; ; ; ;<CR>

XLi responds to all changes with:

OK<CR><LF>

Meaning that Local time will enter DST on the last week of the month. All other parameters remain

unchanged.

The XLi automatically reboots when the user changes the DST entry/exit times in F66.

If any of the items in an input string are invalid, an error message will be returned.

F69 – Time Mode

Use function F69 to select the time mode (time scale) shown or output by:

•

The XLi’s front panel display

The following command line functions (network and serial port):

“F8 - Continuous Time Once-per-Second” on page 46

“F9 - Time On Request” on page 49

•

^{The CODE output on the Main CPU card. (“F90 – Code Output Configuration”}2^{on page 78)}

The PTP packets output by the IEEE 1588 card’s network port (“F131 - Precision Time Protocol

Network Config” on page 119)

Select between the following time scales:

•

TAI (International Atomic Time) is the basis for UTC and GPS time. TAI is the recommended

time scale for IEEE 1588 standard.

_{UTC (Universal Coordinated Time) differs from GPS Time by the addition of}1_leap-second

corrections to compensate for variations in the earth’s rotation.

Standard Time is UTC plus a time zone adjustment. For example, Pacific Standard Time is UTC

minus 8 hours.

GPS Time is derived directly from the GPS constellation and doesn’t contain any leap-second

adjustments or other GPS-to-UTC corrections.

Local Time is UTC plus a time zone and a daylight saving time adjustment.

IMPORTANT interactions between F69 and the IEEE1588 card:

•

When the IEEE 1588 card is operating as a PTP master, if F69 is set to TAI, Local, or GPS, the

1588 port outputs PTP with TAI time.¹

•

When the IEEE 1588 card is operating as a PTP master, if F69 is set to Standard or UTC, the

1588 port outputs PTP with Standard or UTC time respectively.

When the IEEE 1588 card is operating as a PTP slave, only TAI and GPS are valid settings for

F69. the reference source so can cause the XLi to output the incorrect time on the display, the

CODE output, F8, and F9.²

•

F69 has no effect on the IEEE 1588 card operating as a PTP slave. The IEEE 1588 card

operating as a PTP slave expects TAI from PTP.

The factory default for the XLi IEEE 1588 clock is TAI.

1. When F69 is configured for Local or GPS time, the display, the CODE output, F8, and F9 all output Local or GPS

time respectively. Only the IEEE 1588 card “redefines” Local and GPS from F69 as TAI.

2. The XLi requires the value of the offset between GPS and UTC in seconds to compute Local, Standard, and UTC

time. This offset can change by one second, and can potentially be updated at two times during the year. The XLi

typically obtains the offset from GPS while GPS is the primary reference source. The value of the offset isn’t

available from PTP should slave were the reference source). If a PTP slave is the reference source, a reference

source doesn’t obtain the offset from PTP and provide it to the XLi. If the PTP slave and GPS are both reference

sources, the value of offset is not reliable because.

F71 – Oscillator Statistics

Use F71 to display the phase, frequency offset, drift rate, and DAC value of an internal or optional

external oscillator.

Definitions:

The phase is the instantaneous error in seconds between the oscillator and the control loop zero servo

point. The frequency offset is computed using an averaging time that is equal to the effective averaging

time of the oscillator controller. The oscillator Drift Rate is computed using a 24-hour average and is the

daily Drift Rate of the oscillator. The oscillator DAC value is the signed 16-bit integer that controls the

DAC output voltage. It ranges from 0 to 65536.

Alarms - General Information

With Alarm Disabled, an F73 indicator does not trigger and alarm when it enters an Unlocked or Fault

state.

With Alarm Enabled, an F73 indicator triggers an alarm when it enters an Unlocked or Fault state, and

the following events take place:

•

The Alarm Status LED changes color from green to amber or red (See “Alarm Status LED” on

page 25.)

•

The ALARM output on the rear panel changes from low Z to high Z (impedance).

If configured, SNMP sends a trap out over the network port. (See “C: SNMP” on page 151.)

The following items may delay an unlocked or fault state from triggering an alarm immediately:

•

Timeout and Timeout Delay postpone Time Error alarms for a user-configured interval. See

“Timeout and Timeout Delay” on page 71.

Power-on Alarm Suppress prevents alarms from being triggered for a user-configured interval

after the XLi boots and starts. See “Power On Alarm Suppress” on page 72.

Time Error and Time Threshold

Time Threshold sets the threshold in ns above which Time Error triggers an alarm. When the oscillator’s

predicted worst-case time error (“F13 – Time Error” on page 52 ) exceeds Time Threshold, Time Error

enters a fault state.

Note: When Time Threshold is set to zero, it defaults to an appropriate value for the type of refer-

ence source. For example, when Time Threshold is set to “0”, the XLi applies 150 ns as the

value while the reference locked to a GPS reference.

_{When LED Blink is enabled, the Alarm Status LED on the front panel blinks when it is}5_{green or yellow.}

The LED does not blink when it is red, even if LED Blink is enabled. Some users disable LED Blink to

ensure that the LED’s color (state) is displayed without interruption.

Timeout and Timeout Delay

Timeout and Timeout Delay allow you to add the dimension of time to the Time Error indicator. With

Timeout disabled, a Time Error fault triggers an alarm immediately. With Timeout is enabled, a Time

Error fault starts counting down the number of seconds specified by Timeout Delay. When the Timeout

Delay countdown finishes, the Time Error fault triggers an alarm. (Note: the Alarm Status LED on the

front panel turns amber while the Timeout Delay is counting down). If the Time Error fault returns to an

OK state during the Timeout Delay countdown, the countdown clears. A new Time Error fault starts the

Timeout Delay countdown from the beginning. In other words, Timeout Delay countdown does not keep

track of the cumulative duration of multiple Time Error faults.

ALARM ENABLED

Power On Alarm Suppress

Power On Alarm Suppress prevents all F73 alarms from occurring for a specified interval after the unit

starts up. The factory setting is 300 seconds (five minutes). When that interval ends, current and new

alarms are reported normally.

Clear Alarm Latch

Each indicator has an Alarm Latch. The Alarm Latch shows that indicator that has been in an alarm

state, even if it presently reports as “Locked” or “OK”. The Alarm Latch is useful for finding transient

alarms. Clear the alarm latch settings after troubleshooting or fixing the cause of an alarm so new alarms

can be distinguished from previous ones.

Note that an alarm latch only records the occurrence of an alarm if it the indicator’s alarm is enabled.

The alarm latch does not record the occurrence of a fault or unlocked state if the indicator’s alarm is

disabled.

Keypad

Note: The Alarm Latch asterisk is not the same as the “reference source unavailable” asterisk that can

sometimes be seen on the STATUS display.

F74 – Clock Source Control

^{Use function F74 to select the primary and secondary reference sources and configur}1^{e the fail-over}

sequences. The switching modes are:

•

PRI or “Primary”: Ensures the unit remains connected to the primary source and doesn’t attempt

to switch. PRI is the factory setting.

SEC or “Secondary”: Ensures the unit remains connected to the secondary source and doesn’t

attempt to switch.

PRI – SEC – SEC or “Primary – Secondary – Secondary”: the clock synchronizes with the

primary source. If the primary source becomes unavailable, it switches to the secondary source

and stays there, even if the primary source becomes available again. It stays on secondary even

if the secondary source becomes unavailable.

•

PRI – SEC – PRI or “Primary – Secondary – Primary”: the clock synchronizes with the primary

source. If the primary source becomes unavailable, it switches to the secondary source. When

the primary source becomes available again, it switches back to the primary.

PRI – NSEC – PRI or “Primary – No Secondary – Primary”: the clock synchronizes with the

primary source. If the primary source becomes unavailable, it switches to the secondary source.

If the secondary source becomes unavailable, AND the primary is available, switches back to the

primary.

Clock source switching is affected by the setting in F73 Timeout. When a reference source becomes

unavailable, or unlocked, the number of seconds set in F73 Timeout must elapse before the switch

occurs. While the reference source is unavailable the clock relies on a frequency source, such as its own

oscillator or Aux Ref, to keep time. (If Aux Ref is available and enabled, the XLi will use Aux Ref as its

frequency source. See “F113 – J3 Input Configuration (Aux Ref)” on page 104 for more information.)

After the timeout has elapsed, the switching sequence begins.

When a time reference becomes unavailable, the XLi switches to the other time reference, if available.

The configuration of the time reference (e.g., Primary or Secondary) and the settings in F74 – Clock

Source Control (page 77) determine if and how switching takes place. If no other time reference is

available, the XLi will use an Aux Ref frequency input on J3 (“F113 – J3 Input Configuration (Aux Ref)”,

page 104 ) as its reference. If references are available, the XLi “freewheels” on its internal oscillator.

F100 – Network Port Configuration & XLi Firmware

F100 provides two groups of commands:

•

Group 1, available through the keypad/display and the command line, provides access to

network port settings and hardware/Firmware status information.

Group 2, available through the command line only, provides commands for changing system

firmware, changing SNMP parameters, changing the user name/password, resetting the unit,

and pinging other network devices.

Warning: The F100 commands have the capacity to remove the XLi from the network and disable the

XLi’s system firmware. Use judiciously.

Reboot Warning: Saving changes to any F100 parameter using the keypad/display will reboot the XLi.

Some of the F100 command line commands also reboot the XLi. These are identified in the following

documentation.

Group 1

You can use both the keypad/display and the command line interface to access the following

parameters:

•

Ethernet address: XLi contains a unique Ethernet or Media Access Control (MAC) address

comprised of a unique number assigned to the manufacturer, and a unique number assigned to

the unit. This is factory set and cannot be changed.

•

IP Address: Sets a static Internet Protocol (IP) address for the unit.

Subnet Mask: Sets a valid subnet-mask used in IP addressing. Subnetting allows for the more

efficient allocation of network addresses and management of network traffic.

•

Default Gateway: The address of the router that handles packets addressed to IP devices

outside the local-area network.

10 100 BASE-T: The network port bandwidth setting, 10 Base-T or AUTO. (10 Base-T only for

earlier XLi hardware).

Remote Lockout: Enables or disables remote access through the XLi’s standard network port.

Enabling Remote Lockout limits users to the front-panel keypad or Serial I/O port.

•

Flash CRC: Status - Passed or failed.

RAM: Status - Passed or failed.

Serial: Status - Passed or failed.

Version Test: Status - Passed or failed

F100 BUFP – Burn FPGA Firmware

Note: See “B: Upgrading System Firmware” on page 145.

F100 BUFP - Burn FPGA firmware from host to target flash

Use Serial/Network port F100 BUFP when upgrading FPGA firmware - to write the FPGA program file

selected with F100 BH to the flash memory. Prior to issuing the F100 BUFP command, the host

computer must be setup as an FTP server with the new FPGA program file stored on the FTP server.

XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

The existence of the FPGA program file on the FTP server and an Ethernet connection is checked when

the command is issued.

To write the FPGA program to the flash, send the F100 BH command with the FTP host, file path and

name, and then send the following command:

F100 BUFP

This command is only valid for XLi with an 86-8000 Rev. G or higher CPU card. If the CPU card is of the

wrong version, an error message “ERROR: INVALID COMMAND!” will be displayed.

This command is valid only via the command line interface in the following scenarios: (1) the terminal is

communicating to the XLi directly via the serial port, or (2) the terminal is connected to the XLi network

port and the user is logged in as an “operator”. If the terminal is connected to the XLi network port and

the user is logged in as a “guest”, this command will be deemed invalid and an error message, “ERROR:

ACCESS DENIED!” will be displayed.

Prior to burning the FPGA program to the target flash, another error checking step is performed. The

new FPGA program size is checked against the designated memory sector in the target flash. If the

memory sector is not big enough to store the FPGA program, the command will be aborted, an error

message, “FILE FN, EXT (yyy BYTES) TOO LARGE FOR PARTITIONING (zzz BYTES), LOAD

ABORTED” will be displayed, and the new program will not be loaded to the flash.

After all the requirements for burning the FPGA program are met, XLi will proceed to burn the FPGA

program from the FTP host computer to the target flash by responding with the following output string.

OK<CR><LF>

Then, during the file burning process, output strings will be displayed on the terminal to provide status to

the operator. The following is an example of a successful F100 BUFP command execution.

BURNING FILE 184-8000V57.bin WITH SIZE 97652 TO PARTITION:3 SECTOR:10

FLASH SUCCESSFULLY PROGRAMMED

To load the FPGA program from the target flash to the FPGA, a reboot of the XLi is required for the new

FPGA program to take effect. The XLi can be rebooted via power cycle or by issuing the F100 K I L L

command on the serial port interface.

F100 CONFIG – Configure NTP & SNMP

Note: The NTP option is unavailable for the standard XLi IEEE 1588 clock. NTP-related information has

been removed from this section of the manual.

Note: Symmetricom recommends using the Web Interface (versus than F100 CONFIG) as the most conve-

nient method for editing the SNMP configuration file.

XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

Notes:

•

See “A: Using F100 Configuration” on page 141.

F100 CONFIG GET instructs the XLi unit to transfer its SNMP configuration file to an FTP server. After

editing the SNMP configuration file on the FTP server, the user transfers them back to the XLi using the

F100 CONFIG SET command.

Open a Telnet session with the XLi and enter the commands below. Replace <IP Address> with that of

^{the workstation/FTP Server. Leave <subdir> blank (unless you have a specific reason}2^{for placing the}

files in a subdirectory of the anonymous user’s home directory).

To get the SNMP config file, type:

>f100 config snmp get host:<IP Address> dir:<subdir><CR>

Here’s an example of a successful SNMP config file transfer:

>f100 config snmp get host:192.168.0.1 dir:

Host config ip 192.168.0.1 already configured

Source file /config/snmp.conf bytes read: 1275

Dest file snmp.conf bytes written: 1275

Configuration files transferred successfully!

Note: The following steps cause the XLi to reboot.

Using the command line, enter the commands, replacing <IP Address> with the workstation/FTP

server’s IP address.

To move the SNMP config file back onto the XLi, type:

>f100 config snmp set host:<IP Address> dir:<subdir><CR>

Here’s an example of a successful SNMP config file transfer:

>>f100 config set snmp host:192.168.0.1 dir:

Host config ip 192.168.0.1 already configured

Are you sure(y/N)?y

Source file snmp.conf bytes read: 1275

Dest file /config/snmp.conf bytes written: 1275

Configuration files transferred successfully!

Resetting...

After XLi receives the configuration files, it reboots, and goes through the normal startup process.

F100 J – Factory Mode Jumper

Use function F100 J command to test the state of the ‘factory mode’ jumper. A value of 1 means the

jumper is installed and a value of 0 means the jumper is not. The factory mode jumper can be identified

because it is the only three-prong jumper on the CPU card, and is labelled “J3”.

XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

Units are shipped to the customer with no jumper installed. The jumper is used by Symmetricom

technicians to test and configure the unit. With this jumper installed, the operation and integrity of the XLi

are compromised.

Warning: Please do not run the XLi with the jumper, unless specifically directed to do so by a

qualified Symmetricom technician.

To test the state of the factory mode jumper:

F100<S>J<CR>

where:

F100 J FACTORY MODE=0<CR><LF>

F100 K I L L – Reboot

Use function F100 K I L L to reboot the unit. Use F100 K I L L after upgrading the system firmware.

K I L L is a case-sensitive command. When entering this command, use all capital letters and put

spaces between each letter.

To reboot the unit, enter:

F100 K<S>I<S>L<S>L<CR>

For example:

F100 K I L L<CR>

F100 P – Change User Password

Use function F100 P to change a user password. In a network port session, F100 P changes the

password of the user you logged in as; operator or guest. In a serial port session, F100 P changes the

password of the operator user. See “Command Line Interface” on page 29.

_{Valid password size is from no characters to 64 characters. If more than 64 character}5_{s are entered,}

F100 P truncates the string to 64 characters. When selecting a password, use appropriate levels

password security for the XLi’s operating environment. Examples include:

•

Mixing random alpha and numeric characters

Avoiding words or word combinations that can be found in a dictionary

To change the user password, enter:

F100<S>P<CR>

XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

where:

= ASCII character F

100 = unit function number

<S> = space

= specify Password command

<CR> = input line terminator

The XLi responds:

ENTER NEW USER PASSWORD:

When you enter the new password, the XLi responds:

CONFIRM NEW USER PASSWORD:

Enter the same new password again, to confirm the spelling. If the same new password has been

entered twice, The XLi responds:

OK<CR><LF>

In this case, the new password will be used for the next login. However, if the new password is entered

differently the second time, The XLi responds:

ERROR: PASSWORDS DO NOT MATCH. NEW PASSWORD REJECTED.

F100 PI – PING

Use function F100 PI to ping a remote host to see if it is reachable. If no IP Address is provided, F100 PI

uses the XLi’s own IP Address, and tests whether the XLi’s network port has a good network connection.

To ping a known host, enter:

F100 PI<S><IP Address><CR>

For example:

F100 PI 206.254.000.021<CR>

The unit responds (example):

PING 206.254.000.021: REMOTE HOST FOUND.<CR><LF>

PING 206.254.000.021 : REMOTE HOST NOT FOUND.<CR><LF>

XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

To test if the XLi’s network port has a good connection, enter the following using in a serial port session:

>f100 PI<CR>

The Xli responds:

PING : REMOTE HOST FOUND.<CR><LF>

or it responds:

PING : REMOTE HOST NOT FOUND.<CR><LF>

F100 PN – Change User Name

Use function F100 PN to change a user name. In a network port session, F100 PN changes the name of

the user you logged in as; operator or guest. In a serial port session, F100 PN changes the name of the

operator user. See “Command Line Interface” on page 29.

To change the user name, enter:

F100<S>PN<CR>

where:

= ASCII character F

100 = unit function number

<S> = space

= specify User Name command

<CR> = input line terminator

The XLi responds:

ENTER NEW USER NAME:

When you enter a new user name, The XLi responds:

CONFIRM NEW USER NAME:

Enter the same new user name again, to confirm the spelling. If the same new user name has been

entered twice, The XLi responds:

OK<CR><LF>

In this case, the new user name will be used for the next login using the command line interface.

However, if the new user name is entered differently the second time, The XLi responds:

ERROR: USER NAMES DO NOT MATCH. NEW USERNAME REJECTED!<CR><LF>

XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

In this case, the old user name will be used for the next login using the command line interface.

If you have forgotten the operator or guest user name and/or password, use “Bootloader Mode” to

change them. In Bootloader Mode, log in using the factory set user names (“operator”, ”guest”) and

passwords (See “Command Line Interface” on page 29.). Then use F100 PN and F100P to set the new

user names and passwords. Once this has been completed, reboot the unit and log in using the new

username or password. See “F100 P – Change User Password” on page 95.

Bootloader Mode

To enter Bootloader Mode when resetting a forgotten user name (F100 PN) or password (F100 P):

•

Reboot the XLi using the F100 K I L L – Reboot command.

Immediately press the MENU key on the keypad and hold down while the XLi is rebooting. The

XLi will display will ‘hang’ while displaying “BOOTING”.

•

After a few moments, release the MENU key.

Open a command line session with the XLi.

Use the F100 PN or F100 P commands as needed and then reboot the XLi again.

F108 – Oscillator Configuration

Note: The standard XLi IEEE 1588 clock features a TCVCXO oscillator. Other oscillator types are unavail-

able as options for the standard XLi IEEE 1588 clock.

Use function F108 to display the type of oscillator being used:

•

TCVCXO

OCXO

HIGH (High Stability OCXO)

RUBIDIUM

For more information, see “Standard TCVCXO Oscillator” on page 5 .

Command Line

The oscillator type is defined by the hardware configuration of the clock, and is not configured through

the command line or keypad/display user interfaces. To request the oscillator configuration, enter:

F108<S><CR>

The XLi responds:

F108<S>OSCILLATOR<S>CONFIG<S><OSC><CR><LF>

XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

where:

<S>

= ASCII space character one or more

<CR> = Carriage Return, equivalent to pressing the Enter key on a keyboard

<OSC> = Oscillator type: TCVCXO, OCXO, HIGH (High Stability OCXO), or RUBIDIUM

For example, enter the following string:

F108<CR>

F110 – J1 Input (TIET)

Note: The Time Interval - Event Time (TIET) option is included as a standard feature on the XLi IEEE

1588 clock.

Note: Using time code as a reference source is not supported for the XLi IEEE 1588 Clock.

F110 can configure the J1 input port on the Main CPU card as a time code reference source for the

system clock, or it can configure J1 as the input for TIET operation.

Keypad

_{J1 Configuration: (IRIG-A, IRIG-B, NASA 36, TIET) Set to match the type of}5_{time code input.}

•

J1 Time Reference (Available when J1 Configuration is IRIG-A, IRIG-B, NASA 36, not for TIET):

(Primary, Secondary, Standby) Identify the time code input as a primary or secondary reference

source. The function, “F74 – Clock Source Control” on page 77 , uses this designation to for

reference source switching. Standby disables and removes J1 Input as a valid reference source.

Selecting Primary or Secondary automatically bumps another reference source with the same

setting (e.g. F119 – GPS Receiver Configuration ) to Standby.

Note: Configuring F110 for TIET forces J1 Time Reference to Standby. When reconfiguring the J1 as a

time code reference source input, be sure to set J1 Time Reference to Secondary or Primary.

•

Configure Code: (AM, DC) Set to the time code input signal type: AM for amplitude modulated,

or DC level shift. See the time code definitions in “E: Time Code Formats” on page 189 for more

information.

Input Impedance: (For DC: 100 kΩ or 50Ω. For AM: 100 kΩ only.) For DC code, set the

appropriate impedance level for the length of the input cable. Short runs (<200 ft.) get 100 kΩ,

and long runs (>200) get 50Ω.

XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

•

Input Polarity: Positive, Negative

Propagation Delay: (Range 0 to 99999 μS in 1 μS steps) (Factory setting: 1 μS) Compensates

for delay caused by cable length on the J1 input.

•

IRIG Mode: (Sync Gen)

Error Bypass: (Off, 1-10 Frames) (Factory setting: 3 frames) Is used when the IRIG input is

intermittent or has a low signal to noise ratio (SNR). This allows the time code input to ‘flywheel’

for the specified number of invalid time code frames before F110 generates an alarm. Off means

the F73 IRIG input alarm will alarm on the first invalid time code frame. 1-10 means the F73 IRIG

input alarm will alarm after it detects 1-10 invalid consecutive time code frames.

When TIET is selected for J1 Input Configuration, F110 presents the following series of choices:

•

Input Impedance: (100 kΩ or 50Ω) Short runs (<200 ft.) get 100 kΩ. Long runs (>200) get 50Ω.

Input Polarity: Positive only

Upon changing the settings, the last display prompt asks:

Save Changes?: (Yes, No) Yes applies the changes. No cancels the changes.

•

For J1 specifications, see “J1 Input – Time Interval - Event Time” on page 12 .

Notes:

•

Time Code: The XLi expects time code input that provides UTC in 24-hour format. If the time

code does not provide UTC in 24-hour format (e.g., it uses standard, local, or GPS time, or is in

12-hour format), the XLi’s internal clock will be set to the wrong time when it uses the time code

reference, and its time outputs will be similarly affected.

•

Time Code: IRIG and NASA 36 time code don’t contain “year” information. Enter the current year

using F3 before using IRIG as a primary or secondary reference source. Failure to do so can

cause the incorrect time information to be distributed. See “F3 – Time & Date” on page 40 .

At the end of the year, the year increments by one (e.g., 2004 -> 2005) at the end of the year,

provided the XLi is operating during the transition. If it is not operating during the transition, the

time code reasserts the preceding year when used as a reference source.

•

TIET: Put the F110 time code input on STANDBY first before configuring F110 for TIET.

TIET: Stray capacitance loading on the J1 input adversely impacts TIET measurements.

Command Line

F110 can configure the J1 input port to IRIG-A, IRIG-B, NASA 36, TIET Time or TIET Event. Use F110

to enter or request the J1 Input Configuration.

To request the J1 Input Configuration, enter:

Setting the J2 Output Configuration

To set the J2 Output Configuration, send a character string with the previously defined F111 entry format

to the Serial/Network port. Only valid values are accepted. The J2 Output Configuration can be set to

specify one of several predetermined rates. The following sections provide examples (and some

explanations) for each.

The XLi responds:

OK<CR><LF>

F113 – J3 Input Configuration (Aux Ref)

Note: Freq Meas is currently unavailable as an option for the standard XLi IEEE 1588 clock. Most of the

Freq Meas related information has been removed from this section.

Use function F113 to configure the J3 Input for one of the following settings:

•

Auxiliary Reference (Aux Ref) input

Disable all J3 inputs

F113 offers the following keypad settings:

•

J3 Input Configuration: Aux Ref, Freq Meas, Disabled

J3 Input Frequency: 1 MHz, 5 MHz, 10 MHz

J3 Input Impedance: 1kΩ, 50 Ω

The factory settings are Disabled, 10 MHz, and 1kΩ.

For J3 Input specifications, see “J3 Input – Auxiliary Reference” on page 13 .

Auxiliary Reference (Aux Ref) Input:

If an external frequency reference with better long-term stability than the XLi's own oscillator—such as a

Cesium reference—is available, connect it to the J3 connector and enable Aux Ref using F113. Once

this is done, the XLi will use the Aux Ref input (rather than its own oscillator) as its frequency source if

the XLi's reference source(s) become unavailable.

For example, with a single GPS receiver card configured as PRIMARY in F119, and F74 – Clock Source

Control set to PRI,

104

XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

When the XLi reacquires a time reference source and is steering its own internal oscillator, it stops using

Aux Ref as its frequency reference.

For Aux Ref to work:

F119 – GPS Receiver Configuration

Note: The standard XLi IEEE 1588 clock features the GPS C/A Receiver (87-8028-2). Other receiver types

are currently unavailable as options for the standard XLi IEEE 1588 clock.

Summary

Use function F119 to select a specific GPS receiver, display its status information, and configure it as a

reference source.

F119’s functions apply to all models of GPS receiver option cards available for the XLi. Where

differences exist, this manual refers to the card by its name and part number.

In F119, a GPS receivers are identified by number of the option bay where they are located. See

Figure 1 on page 7 for a diagram of the option bay numbers.

F119 provides the following GPS receiver information and status:

•

Availability (indicates the option bay location)

Part Number

Software Version

FPGA Number

GPS Status (Locked or Unlocked)

GPS Antenna (Ok or Open)

GPS Acquisition State (Dynamic Mode, Stop Site Survey, Stop TRAIM, Start Site Survey, Start

TRAIM, Survey Position, Position Hold)

GPS Time Reference (Primary, Secondary, or Standby) Each of F119’s information, status, and

configuration items are explained below. Because F119 is an important function, this section explains the

behavior of F119 and related functions in some detail.

Part Number, Software Version, and FPGA Number

This information is useful for identifying the option card.

GPS Status (Locked or Unlocked)

During normal operation, “Locked” means the receiver has a Time Figure of Merit (TFOM) less than or

equal to 3, or less than 100 ns Estimated Time Error (ETE). Unlocked means the TFOM is greater than

3. For additional information on “good current” GPS satellites, see “F60 – GPS Receiver Satellite List” on

page 60 .

The GPS receiver serves as a time reference for the XLi system clock. To be a valid time reference, the

receiver requires the following information:

•

Current UTC time

The current position of the receiver

110

XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

Following power-up and initialization, the receiver requires at least four concurrent “good current”

satellites to resolve its current position. In rare cases, when a pair of “good current” satellites are on

intersecting paths, the receiver requires additional “good current” satellites or waits for the intersecting

satellites to diverge before resolving the current position. Once resolved, the current position information

is saved.

While resolving its current position, the GPS receiver also listens for the UTC leap-second offset

periodically transmitted by GPS satellites along with GPS time and position information. Up to thirteen

minutes may elapse from the time the receiver acquires its first “good current” satellite to the time it

receives the UTC leap-second offset. Once received, the UTC leap-second offset is saved.

When the receiver has the UTC leap-second value, it starts providing valid time to the XLi system clock.

When the system clock is locked to the GPS time reference and is operating within specifications, the

system status is locked. The interval from initialization to system status lock is typically under twenty

minutes, under nominal conditions. This transition is illustrated below.

Following initialization, the front panel display of an XLi with only one GPS receiver (GPS Status:

Unlocked) would show the following:

UNLOCKED * GPS PRI

LOCAL

365:16:01:05 1969

With the GPS receiver as a valid time reference, the following changes would take place:

•

The asterisk (“*”) indicating the absence of a valid reference would disappear

The system status would change to locked

The front panel status display would look like this:

LOCKED

LOCAL

GPS PRI

233:18:21:29 2004

Once the GPS receiver is a valid time reference, it requires at least one “good current” satellite to remain

a valid time reference. If “good current” GPS satellites become temporarily unavailable, GPS status

changes to unlocked and the XLi stops using the receiver as a valid time reference.

Typically, when a “good current” satellite becomes available again, GPS status locks and the receiver

becomes a valid time reference almost immediately. Typically, the receiver does not need extra time to

resolve its current position unless it is being used in a very mobile/dynamic environment such as an

aircraft.

If the unit is powered-cycled, the receiver repeats the complete position and leap-second acquisition

process before GPS status locks.

Note: GPS satellite visibility and signal strength affect the ability of the GPS receiver to lock and provide

valid time to the XLi. Therefore, it is very important to select the best possible antenna site.

XLi IEEE 1588 Clock

111

997-01510-03, Rev. C, 12/12/2006

GPS Antenna (Ok or Open)

The GPS antenna is powered by a 12-volt current from the ANTENNA connector on the rear of the XLi.

If this circuit is complete (e.g., connected to an antenna) GPS Antenna status is OK. If the circuit is

incomplete (e.g., no antenna, a cable break, or a splitter) the GPS Antenna status is Open. If circuit

detects a short, the receiver opens a relay to disconnect power from the circuit, and the GPS Antenna

status is Open.

GPS Time Reference (Primary, Secondary, or Standby)

Configure the GPS receiver as a Primary or Secondary time reference. This setting is used by F74 –

Clock Source Control to control switching between reference sources. Selecting Standby makes the

receiver unavailable as a reference source.

If one time reference is configured as Primary or Secondary, and another time reference is assigned the

same priority, the first time reference is reset to Standby. For example, with GPS receiver 1 configured

as Secondary, when an operator configures GPS receiver 2 as Secondary and saves changes, GPS

receiver 1 is reset to Standby.

The XLi front panel status display identifies the reference source and its priority (e.g. “GPS PRI”).

GPS Acquisition State

If the user has determined that the receiver will remain in a static location and sets the GPS operation

mode to Time Mode (See “F53 – GPS Operation Mode” on page 58.), the C/A Receiver has the

following acquisition states:

•

Survey Position: The receiver is establishing an initial position following a reset. If the receiver

had “current” satellites prior to being reset, it can establish the position in a matter of seconds;

otherwise establishing the position takes a few minutes.

•

Start TRAIM: (for Time Receiver Autonomous Integrity Monitoring) The receiver is in Position

Hold and is monitoring the integrity of the time solution using redundant satellite measurements

in order to eliminate unreliable signal information.

•

Stop TRAIM: The receiver is ending TRAIM monitoring.

•

Start Site Survey: The receiver is checking for changes in its saved static position (occurs after

boot).

•

Stop Site Survey: The receiver is ending site survey.

Position Hold: The receiver has determined its most accurate position, and is using this static

position to calculate its most accurate time solution.

•

Dynamic Mode: The user has determined that the position of the system could change and has

set F53 GPS operation mode to Dynamic Mode (see “F53 – GPS Operation Mode” on page 58 ).

The system is resolving its position so that it can compensate for position changes.

Option bay location of the IEEE 1588 cards

The option bay number identifies the physical location of the option card in the chassis. The factory

configured location of the IEEE 1588 cards are option bay 4 (PTP master) and, when present for TBD

option bay 2 (PTP slave). For units that have the second IEEE 1588 card (PTP slave), the card is located

in option bay 2. See Figure 7.

Figure 7: Option bay locations (as seen when looking from the side indicated)

Static IP address, subnet mask and default gateway for the network port

The static IP address, subnet mask and default gateway identify the 1588 port on the network.

1. Only displayed when PTP DHCP is set to ENABLE.

XLi IEEE 1588 Clock

119

997-01510-03, Rev. C, 12/12/2006

The IEEE 1588 card (PTP master) located in Option Bay 4 has the following network settings:

•

IP address: 010.048.000.103

Subnet mask: 255.255.000.000

Gateway: 010.024.000.001

For units that have two IEEE 1588 cards, the second card (PTP slave) is located in Option Bay 2 has the

following network settings:

•

IP address: 010.048.000.105

Subnet mask: 255.255.000.000

Gateway: 010.024.000.001

Reconfigure these settings as needed for the 1588 port to operate on the timing network.

The user can reconfigure the static IP settings while DHCP is enabled. The instrument only uses the

static IP settings if DHCP is disabled, or if DHCP is enabled but the 1588 network port hasn’t received

DHCP-assigned settings.

DHCP enabled/disabled

If DHCP is enabled, the IEEE 1588 card automatically obtains IP configuration settings from a DHCP

server on the network. The default factory setting is “enabled”. The DHCP-assigned settings take

precedence over the static IP address settings. The command line interface and keypad display

interface show the DHCP-assigned IP address, subnet, and gateway separately from the static settings.

Note: Enabling DHCP reboots the XLi IEEE 1588 Clock.

DHCP-assigned IP address, subnet mask and default gateway for the network port

The command line and keypad display interfaces display the DHCP-assigned IP address information

separately from the static IP address information. The web interface does not display the DHCP-

assigned IP address information.

Since DHCP is enabled in the factory default settings, if a DHCP server is available from the IEEE 1588

network port, the DHCP-assigned IP address values should be available on the command line and

keypad display interfaces.

PTP Sync message interval

The PTP sync message interval setting determines the length of time between Sync messages multicast

by the PTP master to the PTP slaves. Shorter synchronization intervals improve the timing accuracy of

PTP slaves. Set the PTP Sync message interval to the same value on PTP masters and slaves. The

default factory setting is “2 seconds”.

IMPORTANT: If one of the PTP slaves on the timing network is a Symmetricom IEEE 1588 card,

the interval for all PTP masters and PTP slaves must be set to 2 SECONDS.

XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

PTP burst mode enabled/disabled

With Burst mode enabled, the PTP slave initiates a rapid exchange or PTP messages with the PTP

master in order to synchronize rapidly. To work, Burst mode must be enabled on both PTP master and

slave. This corresponds to the PTP_BURST_SYNC = TRUE in a standard ptpd implementation. Burst

mode is recommended for rapid synchronization of timing networks upon startup and also with longer

sync message intervals (e.g., 64 seconds). PTP burst mode consumes network bandwidth and places

additional demand on PTP masters and slaves on the same timing network. It may saturate PTP

masters and timing networks operating near capacity, particularly if the slaves are all reinitialized at the

^{same time (e.g., a system wide power-cycle). The default factory setting is “disabled”.}2

PTP network port enabled/disabled

Enables or disables the PTP/1588 network port. This feature can be used to put specific PTP nodes

offline without shutting them down. The default factory setting is “Enabled”.

PTP subdomain same

Makes it possible to establish up to four separate timing networks on the same physical subnet. PTP

nodes only synchronize with PTP nodes of the same subdomain; they disregard PTP nodes that are part

of a different subdomain. Configure the PTP masters and PTP slaves with the same subdomain in order

for them to synchronize. The following four subdomain name settings are available: _DFLT, _ALT1,

_ALT2, and _ALT3. The default factory setting is “_DFLT”.

Reset PTP settings to factory defaults

Re-initializes the PTP node and returns the following settings to their factory defaults:

•

PTP SYNC INTERVAL - 2

PTP BURST MODE - DISABLE

PTP PORT STATE - ENABLE

PTP SUBDOMAIN NAME - _DFLT

PTP CLOCK CONFIG, BAY 2 - MASTER

SLAVE SYNC THRESHOLD - 5 microsec

PTP PREFERRED MASTER - DISABLE

The other settings remain unchanged.

The default setting is “No”.

PTP initialize to user entered values

Re-initializes the PTP node and keeps the current parameter settings:

The default factory setting is “No”.

operates as a secondary reference source to the XLi IEEE 1588 Clock.

PTP SLAVE STBY - the IEEE 1588 card functions as a PTP slave on the timing network but does

not operate as a reference source to the XLi IEEE 1588 Clock.

See “F74 – Clock Source Control” on page 77 for more information about reference sources.

IMPORTANT: If one of the PTP slaves on the timing network is a Symmetricom IEEE 1588 card,

the interval for all PTP masters and PTP slaves must be set to 2 SECONDS.

PTP Slave Synchronization Threshold

Sets the synchronization threshold for the PTP slave to lock to the PTP master, determining whether the

F130 parameter SLAVE CLOCK SYNCHRONIZED reports LOCKED or UNLOCKED. Use the 5

microsecond setting for timing networks that traverse approximately 2 hubs or switches. Try the 1000

microsecond setting if the PTP slave is having difficulty synchronizing or remaining synchronized on

timing networks with the following characteristics:

•

Multiple layers of hubs and switches

Routers

Heavy or bursty network traffic levels

The default factory setting is “5 microseconds”.¹

PTP Preferred Master Configuration

PTP slaves synchronize with PTP masters that have the preferred master setting enabled versus those

that don’t. Enable this setting to ensure that PTP slaves remain synchronized to a particular PTP master

or set of PTP masters.

The default factory setting is “Disable”.

A: Using F100 Configuration

Configuring SNMP Parameters

Note: The NTP option is currently unavailable for the standard XLi IEEE 1588 clock.

^{F100 CONFIG instructs the XLi unit to transfer SNMP configuration file to an FTP serv}2^{er so the user can}

edit it. When finished editing, the user transfers the config file back to the XLi using the F100 CONFIG

command.

Overview of Steps

•

Set up an FTP server on your workstation.

•

Using the XLi’s command line interface, enter the F100 CONFIG getcommand. The XLi

transfers copies of its configuration files over the network to the FTP on your PC.

•

Edit the configuration files.

Give the XLi a new command, F100 CONFIG set. The XLi retrieves copies of the edited

configuration files from the FTP and overwrites it’s current config files with the newly edited ones.

Set up the FTP Server

To save time and trouble, download a pre-configured FTP server from http://www.ntp-systems.com/zip/

warftpd1.zip and extract it to the C:\ drive on your workstation. Otherwise, customize your existing FTP

server setup as described in this section.

When performing these operations, the user issues command line instructions to the XLi. The XLi

responds to those commands by connecting to the FTP server and transferring files to and from the FTP.

The XLi gives the FTP server ‘Anonymous’ as its user name, and uses a null password (e.g., the

equivalent of pressing the Enter key on your keyboard instead of entering text). The FTP server must be

configured as follows:

•

Anonymous log-ins are enabled

The password for Anonymous is disabled, or allows a null password

Anonymous has read/write privileges to Anonymous’s home directory.

Get the IP Address of the FTP Server/Workstation

If the FTP server is running on your Windows workstation, open a DOS command line window on the

workstation:

•

Click Start, Run, and type cmd, or

Click Start, Programs, (and Accessories in some cases), and select Command prompt or

DOS prompt.

•

At the command line, type ipconfig

Make note of the IP Address.

XLi IEEE 1588 Clock

141

997-01510-03, Rev. C, 12/12/2006

For other operating systems and configurations, consult the appropriate documentation for obtaining the

FTP server’s IP address.

Copy the Configuration Files to the FTP Server

Telnet to the XLi or open a terminal session to it over the serial port.

Using the command line, enter the commands below. Replace <IP Address>with that of the

workstation/FTP Server. Leave <subdir>blank - the FTP server will save the files in anonymous’s

home directory.

Note: See “Command Line Interface” on page 29 if you need instructions for connecting to the com-

mand line interface

To get the SNMP config file, type:

>f100 config snmp get host:<IP Address> dir:<subdir>

Here’s an example of a successful SNMP config file transfer:

>f100 config snmp get host:192.168.0.1 dir:

Host config ip 192.168.0.1 already configured

Source file /config/snmp.conf bytes read: 1275

Dest file snmp.conf bytes written: 1275

Configuration files transferred successfully!

If you get “Error: Can’t write file” when you enter the get command, verify the following FTP

server items:

•

FTP server is running.

Anonymous has a home directory.

The home directory for Anonymous has read, write, and delete enabled (make sure to apply

changes).

Edit the Configuration Files

In Windows, edit the configuration files using a text editor such as Notepad or Wordpad.

If using the pre configured FTP server (downloaded from http://www.ntp-systems.com/zip/warftpd1.zip),

the FTP places the configuration files in C:\TrueTime, the default or home directory of “anonymous”.

Note: Follow these guidelines when editing the configuration files:

•

If the editor displays odd 'box' characters or the lines of text don't wrap properly, close the file

without saving changes and switch to a different text editor.

•

Don't rename or save the configuration files as a new file type.

Some text editors encode end-of-line carriage returns that cause errors when XLi refers to the

file. Notepad, WordPad, Microsoft Word, and Vim don't seem to have this problem.

The configuration files are automatically transferred to/from the FTP server in binary format.

They retain the DOS or UNIX file conventions of the editor. XLi works with either format.

Move the Configuration Files Back to the XLi

Reboot Warning: The following steps cause the XLi to reboot.

Using the XLi’s command line, enter one of the commands below, replacing

<IP Address> with the IP address of your workstation/FTP server.

To move the SNMP config file, type:

>f100 config snmp set host:<IP Address> dir:<subdir>

Here’s an example of a successful SNMP config file transfer:

>>f100 config set snmp host:192.168.0.1 dir:

Host config ip 192.168.0.1 already configured

Are you sure(y/N)?y

Source file snmp.conf bytes read: 1275

Dest file /config/snmp.conf bytes written: 1275

Configuration files transferred successfully!

Resetting...

If you get “Error: Can’t open source file”, verify that the FTP server’s <<Local Server>> is

running.

After XLi receives the configuration files, it reboots, and goes through the normal startup process.

B: Upgrading System Firmware

Caution: Consideration must be given to the firmware and the hardware version numbers of the XLi and it’s optional com-

ponents. Consult with Symmetricom’s Customer Service department before performing upgrades.

This section explains how to completely upgrade the system firmware. This is done using the F100 BH,

F100 BUB, F100 BU, and F100 BF commands.

Overview of Procedure

•

Set up a network connection between your XLi and the FTP server.

Set up an FTP Server with the firmware upgrade files.

Open a command line session to the XLi.

Install the firmware version 8 files.

Reboot the XLi.

Note: If your system’s and SNMP configuration file (snmp.conf) has been customized, make a backup

copy and later re-install that configuration file. See “A: Using F100 Configuration” on page 141 .

Set up the FTP Server

To save time and trouble, download a preconfigured FTP server from http://www.ntp-systems.com/zip/

warftpd1.zip and extract it to the C:\ drive on your workstation. Otherwise, customize your existing FTP

server setup as described in this section.

When performing these operations, the user issues command line instructions to the XLi. The XLi

responds to those commands by connecting to the FTP server and burning the software to system

memory. The XLi gives the FTP server ‘Anonymous’ as its user name, and uses a null password (e.g.,

the equivalent of pressing the Enter key on your keyboard instead of entering text). The FTP server must

be configured as follows:

•

Anonymous log-ins are enabled

The password for Anonymous is disabled, or allows a null password

Anonymous has read/write privileges to Anonymous’s home directory.

Obtain the current system firmware files (E.g., 192-8001.bin, 192-8000.bt, 192-8002.fs) from

Symmetricom’s customer support website.

Place the system firmware upgrade files in home directory of the ‘anonymous’ user. If you’re using the

preconfigured FTP server, C:\TrueTime is the default or home directory.

Open a Command Line Session on the XLi

Note: The XLi and FTP server need to be connected by a TCP/IP network. Ideally they should be on an

isolated subnet. Connecting them over a network with multiple ‘hops’ or one with heavy network

traffic raises the possibility that the system software files could be corrupted, yielding the XLi

inoperable.

XLi IEEE 1588 Clock

145

997-01510-03, Rev. C, 12/12/2006

Telnet to the XLi over the network. For example, at your workstations command line, type “telnet

192.168.46.10”.

When prompted, log in to the unit using the operator’s username and password; the user name and

password are usually “operator” and “janus”.

Upgrade the Firmware

Command Format

When issuing the firmware upgrade commands, use the following format:

F100 <command> <ftp_server_ip_address> <relative_path>/<file.ext>

If the FTP server is on your workstation, <ftp_server_ip_address>is the IP address of your

workstation.

<relative_path>is a subdirectory inside the anonymous user’s home directory on the FTP server. If

there is no subdirectory (i.e., if the upgrade files are sitting in anonymous user’s home directory), drop

<relative_path>from the command line.

For example, if c:/ftpworkfiles is the anonymous user’s home directory, and the upgrade files are in c:/

ftpworkfiles/xli/, you would enter the command as follows:

F100 bh 192.168.49.120 xli/192-8000.bt

On the other hand, if the files are in c:/ftpworkfiles, the anonymous user’s home directory, you would

drop the <relative_path>and enter the command as follows:

F100 bh 192.168.49.120 /192-8000.bt

Issuing the Upgrade Commands

Adapt the following examples as needed to match your system, such as differences in IP address,

path, and filename).

Enter the following command:

F100 bh <IP_address> <relative_path>/<file.bt>

For example:

F100 bh 192.168.49.120 /192-8000.bt

XLi responds:

BURN HOST IS READY<CR><LF>

Then ‘burn’ the bootloader to the XLi’s flash memory by entering:

F100 bub

The “K I L L” command reboots your unit. You have completed the firmware upgrade procedure

Troubleshooting

Most problems upgrading the firmware are due to problems with the configuration of the FTP server,

such as:

•

setting the server to accept a null password

configuring the anonymous home directory

setting the correct access rights

entering the correct relative file path

The following error messages may provide some indication of the underlying problem:

Message: >Can't set the burn host - wrong IP address

Cause: The IP address entered for the FTP server is incorrect. Check that you've entered the IP address

of the FTP server (not the XLi) and re-enter if necessary.

XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

Message: >Can't open file: 192-####.##

Cause: There's a problem with the FTP server that is preventing access to the file. Verify the following:

•

The FTP server is correctly configured.

The anonymous user account is enabled.

The anonymous user account password is “guest”.

The anonymous user account has read access to the ftpworkfiles directory.

The ftpworkfiles directory located in the anonymous user's home directory.

The FTP server is running.

There aren’t any other ‘anonymous’ users logged into the FTP server.

Try connecting to the FTP server as ‘anonymous’ using an FTP client. You should automatically see the

product name directory (e.g., “XLi”) you created inside the anonymous users home directory (e.g.,

“c:\ftpworkfiles\”). Open the product name directory. You should see the firmware upgrade files you put

there. If either the product name directory or the firmware upgrade files aren’t visible, there’s a problem

with the FTP configuration.

Message: >Wrong File type

You may be using the wrong firmware files for the product being upgraded. This may be due to the

incorrect files being place in the upgrade directory. It may also be that the wrong directory was entered

(one for another product) in the path information on the F100 command line. ‘Wrong file type’ is also

associated with ‘Can’t open file’ errors - see the preceding message.

Message: Unit hangs on “Burning Boot” message.

Check that your IP Address, Subnet Mask, and Default Gateway of the XLi are correctly configured.

FAQ

How does one check the unit’s firmware version number?

Log on to the XLi and enter the following command:

> F100 VER

An example XLi response is:

F100 VER

BOOTLOADER

SOFTWARE

192-8000

192-8001

FILE SYSTEM 192-8002v1.80

NVRAM VER

PROJ REV

#1.80

The “PROJ REV” number is the firmware version number. The “v” number in “FILE SYSTEM” is the file

system version number, which may not be the same as the firmware version number.

XLi IEEE 1588 Clock

149

997-01510-03, Rev. C, 12/12/2006

How does one check the IP address, subnet mask, and default gateway of the

XLi?

Log on to the XLi and enter the following command:

> F100 IC

F100 IP:192.168.47.156 SM:255.255.255.0 G:192.168.47.1

Is the null modem cable necessary? What if I’m upgrading a XLi remotely?

The null-modem cable is optional. If you decide to Telnet to the XLi over TCP/IP network, you don’t need

the null modem cable.

I’m using a null modem cable to connect to the XLi from my laptop and the

XLi keeps rebooting?

An ungrounded voltage level on one of the pins in the null modem cable causes the unit to reset. Use

one of the following work-arounds:

•

Connect the laptop to a grounded power supply, if it has one, or ground the laptop’s chassis.

Do away with the null modem cable. Telnet to the unit over the network.

Use a regular PC instead of the laptop. The PC is connected to a grounded power supply and doesn’t

cause this problem.

Editing snmp.conf

By default, SNMP is disabled. To enable SNMP or configure its parameters, follow the steps outlined

below. Please open, edit, save, and close the snmp.conf file without changing its name or saving it as a

new file type. An example “snmp.conf” file might look like the following, with each string that follows

NAME=appearing as a single line in the text file:

MIB=/config/ttmib.o,

GenTraps=YES,

NAME=public,VIND=1,TRAP=YES,ACCESS=R,IP=010.001.007.065,IP=000.0

Key:

MIB=/config/ttmib.o, Don’t touch. This is a factory setting.

GenTraps=YES,

Global enable/disable setting for all SNMP traps. YES, the default setting,

enables all traps. NO disables all traps. This setting overrides all the other TRAP

parameter settings.

NAME =

VIND =

the community name password. This should be the same as the community

name being used by the administrator's

View Index. This is a reserved term that has no effect and is currently unused in

SNMP. This parameter should be set to “1”.

TRAP =

YES enables/NO disables SNMP traps for a particular community.

ACCESS =

Read and write privileges to members of a community. R sets read only

privileges, and W sets read and write privileges.

IP =

Provide the IP address of the SNMP management stations within that

community. These addresses are required in order for the management station

to receive SNMP traps and to communicate with the XLi system using SNMP.

Note: A special address of 255.255.255.255 grants any IP addressed unit

access to the Enterprise MIB variables.

SNMP Private Enterprise MIB Structure

This section describes the top level structure & design of the XLi SNMP Private Enterprise MIB.

SNMP Addressing

SNMP addressing is structured as a very large tree database. A root node address is an integer value

that ranges from 0 to some very large number. Conceptually, there are no limits to the numbers of sub

nodes either. SNMP addressing is written in “doted decimal” notation. For example the address of

Symmetricom’s ntpInPkts Enterprise MIB variable is “1.3.6.1.4.1..1896.6.1.2.1.1.0”. The address

fragment 1.3.6.1.4.1 is fixed by the IANA (Internet Assigned Number Authority) and is the address of the

SNMP Private Enterprise MIB’s. The 1896 is the address assigned by IANA to Symmetricom for our

Enterprise MIB’s. Symmetricom assigns the addresses after that at our discretion and design.

New Top Level Structure of Enterprise MIB for XLi

The former address structure of Symmetricom’s Enterprise MIB is as follows:

TrueTimeEnt = 1896

TrapMsg = 1

ntp = 2

ntsControl = 3

gps = 4

acts = 5

XLi IEEE 1588 Clock

177

997-01510-03, Rev. C, 12/12/2006

For the XLi, groups 1, 2, 3, 4 and 5 have been deprecated and a new group 6, products, has been

added. For the XLi and future Symmetricom products, groups 1 through 5 will be absent from the XLi

Enterprise MIB definition supplied with the unit. The top structure for the XLi is:

TrueTimeEnt

= 1896

products

= 6

Additional

Products

xli

xliSystem

xliTrap

systemStatus

Cards

systemStatus

General

systemAlarmData

= 1

systemFault

Config

systemStatus

Detail

= 2

systemFault

History

= 3

The level under the xli group is divided into four groups; the first two of which will be explained later. The

optionCardGroup has all the available option cards under it. Under each option card is a table for that

option card type because there may be multiple cards of that type within an XLi chassis.

The current traps message group is located under the fault. The ntp group is under the xliMainCard

group as an option, and is related to only to NTP on the standard network port on the XLi’s Main CPU

card. For each instance of an NTP option card, the NTP group will be repeated under the optionCards

group. GPS is located under the optionCards group, and is repeated for each GPS option card. The

ntsControl and acts groups have not been implemented for the XLi.

178

XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

This MIB structure also provides a useful definition for the system object ID. SNMP managers may use

the system object ID to identify the class of object being accessed. With this structure, the system object

ID is defined as Truetime.products.xli for the XLi product and Truetime.products.xxx for all subsequent

products.

XLi System Group

The XLI system group contains the xliFault and the xliStatus groups. These groups contain information

describing the operation of the XLI system as a whole. The xliFault group contains information

concerning system faults that have occurred, as well as configuration parameters for the generation of

system alarms, called traps in SNMP, resulting from those faults. The xliStatus provides two different

views of the operational system. The first is a general view specifying if the clock is operational. The

second is a detailed view containing the current status of each system component. The xliFault and

xliStatus groups are described below.

The XLI systemAlarmData group defines SNMP traps and cannot be directly retrieved by the SNMP

manager. When a system alarm event occurs an SNMP trap alarmSystemNotification is sent to the

SNMP managers previously configured to receive traps. Included in the trap message are the variables

contained in the systemAlarmData group: IP address, timestamp, alarm code, and the F73 status string.

The systemFaultConfig sub-group contains parameters to control the generation of system alarms. The

timeout, threshold and power on suppress values are contained in the systemFaultConfigData group.

Also in this group is a method object configDataLatchClear. By setting this object the user clears all

latched faults. Reading the configDataLatchClear object has no effect and its value is not defined. The

systemFaultConfigMasks group contains masks for each possible system alarm event. When the status

changes, for example if the primary GPS becomes unlocked, the associated mask is checked. Only if

the mask is enabled will a system alarm be generated.

The systemFaultHistory group contains latched status indicators for each of the system alarm events. If

a system alarm event goes into fault status, even if this status is transient, then the associated entry in

the systemFaultHistory group will maintain a record of that fault occurrence until the latch is cleared,

using the configDataLatchClear object, resetting all systemFaultHistory entries.

the reference clock source. The systemStatusGeneralGroup also contains the statusDescriptorStr object

that returns a text string identical to the output of the F73 command on the command line interface. The

systemStatusDetail group contains objects describing the current status of each system object. See the

graph above and refer to the xliSystem-SMIv2.mib MIB for a complete description of each object.

At present the xliMainCard group contains only the NTP subgroup as shown above. Refer to the

xliMainCard-SMIv2.mib MIB definitions for a description of each of the NTP statistics.

XLi Traps

All traps for the XLI product are defined under Truetime.products.xli.xliTraps. This is required to maintain

compatibility with MIBS defined using the Structure of Management Information version 1 definitions.

The XLI SNMP agent will send SNMP version 1 traps. This is done to maintain compatibility with

SNMPv1 managers.

The traps presently defined are: alarmSystemNotification

The alarmSystemNotification trap is sent when the state of an object in the systemStatusDetail group

changes and the corresponding mask object in the configDataMasks group is enabled.

Future Expansion

This section outlines the possibilities for future expansion of the TrueTime Enterprise MIB. The general

overview is that new objects may be added to any location. Existing objects may not be altered in order

182

XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

to maintain backward compatibility. There are two varieties of expansions to consider: additional

products and additional features within an existing product.

This model makes adding additional products and maintaining compatibility a straightforward process.

Each additional product will be given a branch in the tree under enterprises.Truetime.products. For now,

we have only enterprises.Truetime.products.xli and enterprises.Truetime.products.nic56k.

Future products will take the form enterprises.Truetime.products.product.XXX. Each product will use

enterprises.Truetime.products.product.XXX as its system object identifier. Each product will also define

an enterprises.Truetime.products.product.XXX.xxxTrap subgroup for the definition of all enterprise

specific traps that can be generated by that product.

Making additions to the XLI product MIB is also a straightforward task with several caveats. The first is

that additions may be made but the object identifier and the semantics of existing objects may not be

altered. A likely place for additions is under the systemStatusDetail group as addition system objects are

defined.

A place holder group xliOptionCards has been defined but currently has no accessible members. This

group will be used for the management of optional add on cards. It is suggested that each sub-group

under xliOptionCards be defined as a table to allow for the possibility of multiple option cards of a

particular type.

Glossary of SNMP-Related Terms

Depreciation: In SNMP when an SNMP variable or group of variables is no longer recommended for

use, they are listed as deprecated in the formal definition of the MIB. Users are often times still allowed

to use this data, but the MIB’s authors for one reason or another no longer recommend it.

Enterprise MIB: See Private Enterprise MIB.

IANA - Internet Assigned Number Authority: This is the group at IETF that is in charge of assigning

^{Internet related numbers like Ethernet addresses, TCP/UDP port numbers and SNMP}5^{Private Enterprise}

MIB numbers.

IETF – Internet Engineering Task Force: The group responsible for standardizing numerous Internet

communication protocols.

Management agent: An Internet connected remote host that accumulates the raw data that is entered

into the MIB and Enterprise MIB for that host. This data is at some point transmitted to a Management

station. In other network applications this would be called a network server of the SNMP protocol.

Management station: An Internet connected remote host that consumes SNMP data provided by a

Management agent for the display of human network managers. In other network applications this would

be called a client of the SNMP protocol.

MIB – Management Information Base: This is the data structure for the SNMP protocol. The current

version of this standard, that is in general use, is MIB II defined by RFC’s 1213 and 1212.

XLi IEEE 1588 Clock

183

997-01510-03, Rev. C, 12/12/2006

NTP – Network Time Protocol: A network time distribution protocol developed at the University of

Delaware under the direction of Dr. Mills. NTP is a client / server based protocol where the server is the

supplier of time and the client is the consumer of the time information.

Private Enterprise MIB: SNMP allows private organizations to define their own MIB extensions. The

IANA of the IETF issues, for a fee, a unique number to an organization that is an address entry point

from the MIB II into the private data for that organization. Only one Enterprise address is assigned to an

organization. The Enterprise address for Symmetricom is 1896. This address space has grown to over

12,000 private addresses and Symmetricom is by comparison one of the earlier adopters of SNMP with

an Enterprise MIB!

RFC – Request for Comments: A document reviewed and released by the IANA that defines the formal

definitions of various Internet communication protocols and related information.

SNMP – Simple Network Management Protocol: This Internet communications protocol is used for

the status and control of remote network devices. Numerous IANA standards committees starting in

1990 and continuing to day define this protocol.

Trap or Trap Message: A packet issued from an SNMP Management agent to an SNMP Management

station. The message is intended to relay and important even that occurred within the agent that requires

attention or notification.

E: Time Code Formats

The following section provides a summary description of the three time code types used by the XLi. The

definitive IRIG time code specification, the Range Commanders Council’s IRIG Serial Time Code

Formats, IRIG Standard 200-98, is available on the Web at http://jcs.mil/RCC/manuals/200/

Overview

Please refer to the Input and Output specifications in the front of the manual for details regarding the

voltage amplitudes / modulation ratios of the following time codes provided or used by the Model XLi.

IRIG

Introduction

The document 200 95 "IRIG STANDARD TIME FORMATS" by the Telecommunications Working Group,

Inter range Instrumentation Group, Range Commanders Council describes IRIG-B and IRIG-A time

codes.

The standard time formats of IRIG codes were designed for use in missile, satellite and space research

programs. Use of these codes facilitates efficient interchange of test data. These formats are suitable

for recording on magnetic tape, oscillographs, film and for real time transmission in both automatic and

manual data reduction. IRIG-B from the Model XLi is suitable for remote display driving, magnetic tape

recording and many other uses. IRIG codes, in the strict sense, encode Universal Coordinated Time

(UTC) in 24 hour format and not local time. Nonetheless, this instrument can encode UTC or local time

in either 24 or 12 hour formats.

IRIG Code Format

Reference “IRIG Standard Format A” on page 192 . The level shifted, pulse width modulated, serial

formats of IRIG-B and IRIG-A are divided into three segments. The first segment encodes time of year

in binary coded decimal (BCD) notation. The second segment encodes control functions. This segment

is generally available for data of the user's choice. In the IRIG-B code output of Model XLi, this segment

encodes worst case time error flags as explained below. The IRIG-A output from Model XLi does not

include control functions. The third segment sometimes encodes time of day in straight binary seconds

(SBS) notation. Both IRIG-B and IRIG-A encode SBS on the Model XLi.

The three code segments are contained within one "frame". The frame length for IRIG-B is 1 second

long and contains 100 "elements" (pulses) each of which start every 10 milliseconds. The frame length

for IRIG-A is 1/10 seconds and contains 100 elements each of which starts every 1 millisecond.

An element may represent either a binary zero, a binary one, a reference marker or a position identifier.

A zero is 0.2 of the duration of an element, a one is 0.5 of the duration of an element and a position

identifier or reference marker is 0.8 of the duration of an element. A reference marker locates the

XLi IEEE 1588 Clock

189

997-01510-03, Rev. C, 12/12/2006

beginning of each frame and a position identifier marks the end of every ten elements. IRIG-B and IRIG-

A have ten position identifiers per frame.

The elements prior to position identifier P5 comprise the time of year segment. The first ten elements

encode the seconds, the second ten elements encode the minutes and so on through days. Each

element is a digit in a binary number with a place value sequence 1 2 4 8.

IRIG-B Time Quality Flags

Five flags are encoded in the control function segment of the IRIG-B code. The first flag encoded at

element P5+40ms is the LOCK indicator. It is a binary 1 when the XLi is not locked to a reference. The

second flag encoded at element P5+60ms is a binary 1 when the worst case time error exceeds

threshold 1 (refer to "Function 5 -- Time Quality Enable/Setup"). Element P5+70ms is a binary 1 when

the worst case time error exceeds threshold 2. Element P5+80ms encodes a binary 1 when the error

exceeds threshold 3 and P5+90ms when the error exceeds threshold 4.

Output

The XLi provides the following IRIG time code outputs (refer to IRIG Standard 200-95):

IRIG-B: B120

B000

1 KHz sine wave amplitude modulated with BCD, CF, SBS

DC level shift, width coded with BCD, CF, SBS

1 KHz sine wave amplitude modulated with BCD, SBS

DC level shift, width coded with BCD, SBS

IRIG-A: A133

A003

Input

The XLi can also synchronize and lock to IRIG-B and IRIG-A input codes. The required input code does

not need to have the CF or SBS elements. The XLi only decodes the BCD portion of the incoming code.

IRIG-B: B122

1 kHz sine wave amplitude modulated with BCD

XLi IEEE 1588 Clock

997-01510-03, Rev. C, 12/12/2006

Coordinated Time (UTC) in 24 hour format and not local time. Nonetheless, this instrument can encode

UTC or local time in either 24 or 12 hour formats.

NASA 36 Code Format

The level shifted, pulse width modulated, serial format of NASA 36 is divided into two segments. The

first segment encodes time of year in binary coded decimal (BCD) notation. The second segment

encodes control functions (unused on Model XLi).

The two code segments are contained within one "frame". The frame length for NASA 36 is 1 second

long and contains 100 "elements" (pulses) each of which start every 10 milliseconds.

An element may represent either a binary zero, a binary one, a reference marker or a position identifier.

A zero is 2 ms, a one is 6 ms, a position identifier is 6 ms. A reference marker is 5 consecutive position

identifiers. A reference marker locates the beginning of each frame.

Output

The XLi provides the following NASA 36 time code outputs:

NASA 36 (AM):1 KHz sine wave amplitude modulated BCD

NASA 36 (DC):DC level shift, width coded BCD

Input

The XLi can also synchronize and lock to the following NASA 36 input codes.

NASA 36 (AM):1 KHz sine wave amplitude modulated BCD

NASA 36 (DC):DC level shift, width coded BCD

Glossary of IEEE 1588-related Terms

Boundary Clock: Generally a switch with more than a single IEEE 1588 equipped port, which is a slave

on one port and a master on all others.

Grandmaster Clock: Within an IEEE 1588 subdomain, a Grandmaster clock is the ultimate source of

time for clock synchronization using the IEEE 1588 protocol.

^{IEEE 1588 Ordinary Clock: A IEEE 1588 clock with a single port. Precision Time Pro}2^{tocol (PTP): The}

protocol defined by the IEEE 1588 standard.

Transparent Clock: In IEEE 1588 terminology, it is a switch that compensates for its own queuing

delays. Neither master or slave.
