About This Book
Overview

Overview
The DEFINITY ATM (asynchronous transfer mode) combines portions of the
DEFINITY platform with an ATM switch platform that meets specific criteria.
DEFINITY ATM offers both intraswitch and interswitch ATM solutions. The
intraswitch solution is called the ATM port network connectivity, or ATM-PNC, and
the interswitch solution is called ATM circuit emulation service, or ATM-CES.
ATM-PNC is only available on the R6.3r or later platform.
ATM-PNC provides an alternative to either the direct connect or center stage
switch configurations for connecting the processor port network (PPN) to one or
more expansion port networks (EPNs). ATM-PNC is available with four DEFINITY
ECS reliability options—standard, high, ATM network duplication, and critical.
Customers must choose whether they want direct connect, CSS, or ATM-PNC. It
is not possible to mix configurations in the same R8r platform.
ATM-CES lets the DEFINITY ECS emulate an ISDN-PRI trunk on an ATM facility.
These virtual trunks can serve as integrated access, tandem, or tie trunks.
ATM-CES emulates up to 8 ISDN spans on a single OC-3/STM-1 ATM interface.
ATM wide area network (ATM-WAN) extends the port network connectivity
beyond a single ATM switch over large distances. This allows you to use either a
private ATM network, public WAN or a combination of both. Several networked
ATM devices can be used as effectively as a single ATM switch for inter-port
network connectivity.
The DEFINITY ECS switch can connect through several ATM switch types, many
of which are sold through Lucent’s InterNetworking Systems (INS) channel,
formerly know as DNS. Also, DEFINITY ECS switches are designed to work
seamlessly with non-Lucent ATM switches that meet ATM standards set by the
European Union.
For a current list of Lucent switches, go to the Infohub Web site

Antistatic Protection
!
WARNING:
To minimize electrostatic discharge (ESD), always wear an authorized wrist
ground strap when handling circuit packs or any components of a
DEFINITY System. Connect the strap to an approved ground such as an
unpainted metal surface on the DEFINITY ECS switch.
Remove/Install Circuit Packs
!
CAUTION:
The control circuit packs with white labels cannot be removed or installed
when the power is on. The port circuit packs with gray labels (older version
circuit packs had purple labels) can be removed or installed when the
power is on.
Security
To ensure the greatest security possible, Lucent Technologies offers services that
can reduce toll fraud liabilities. Contact your Lucent Technologies representative
for more security information.
Login security is an attribute of the DEFINITY ECS software. Advise customers
that their existing passwords expire 24 hours after the upgrade. Also explain that
the new passwords must conform to strict requirements.
System administrators must keep network addresses confidential. A PPN or any
endpoint masquerading as a PPN on the ATM network can seize that EPN and
control it if that EPN is not already connected to its proper PPN.

access dialing codes is a violation of the Telephone Operator Consumers Act of
1990.
This equipment complies with Part 68 of the FCC Rules. On the rear of this
equipment is a label that contains, among other information, the FCC registration
number and ringer equivalence number (REN) for this equipment. If requested,
this information must be provided to the telephone company.
The REN is used to determine the quantity of devices which may be connected
to the telephone line. Excessive RENs on the telephone line may result in devices
not ringing in response to an incoming call. In most, but not all areas, the sum of
RENs should not exceed 5.0. To be certain of the number of devices that may be
connected to a line, as determined by the total RENs, contact the local telephone
company.
NOTE:
REN is not required for some types of analog or digital facilities.

Request Address Information
The complete DEFINITY ECS translations require precutover administration,
which, in turn, requires a customer address scheme, specifically the ATM
addresses for theTN2305/TN2306 ATM interface circuit pack(s). The address of
the EPN is automatically read by the local ATM switch, using the address
registration procedure defined in Integrated Local Management Interface (ILMI).
If field technicians do not have the login permissions required to obtain the EPN’s
ATM address(es) directly from the ATM switch(es), the customer or ATM switch
installer must provide that information.

2. High reliability requires 2 ATM-EI circuit packs in the PPN and 1 ATM-EI in each EPN.
3. The number and uses of the synchronization splitter depend on the configuration and the source(s)
from which primary and secondary synchronization is derived. You may need 1 sync splitter per
ATM switch. DS1 synchronization requires either no sync splitter or up to a number twice the
number of sites.
4. Existing fiber optic cable may require an ST-to-SC adapter, depending on the interface at the ATM
switch. The TN2305/TN2306 circuit pack requires an SC connector (1 adapter is included in the
Fiber Pass-Through Kit).
5. For network duplication; required for systems supporting PRI, BRI, or ASAI.

Determine ATM Switch Suitability
To fully support DEFINITY ATM-PNC and provide nonblocking ATM access
between all port networks, ATM switches must support at least 400
point-to-multipoint switched virtual connection (SVC) roots or leaves per
OC-3/STM-1 interface. Because different switches have different limits—some
limit roots, some leaves, and some the total, we have developed the Meiners’
Algorithm to determine whether a switch can support a proposed set of port
networks in a proposed switch. This algorithm is available to Lucent engineers as
a calculator within a Microsoft Excel spreadsheet. You may access the MS Excel
updates.
For best results, use the calculator for one ATM switch at a time. Use trial and
error to set the values in the user-defined values section until the feasibility
indicator reports YES or PROBABLY.
NOTE:
Use of this spreadsheet is no substitute for thinking. Please apply basic
sanity checks to the outcome. ATM switches may have limitations that the
calculator does not consider.
To use the calculator, type the network layout and resource limits for the ATM
switch you are using. Refer to the following caveats as you input your information:
1. Not all ATM switches have limits on all of the values. If a limit does not
apply, enter any very large number (1000000 is good).
2. Some ATM switches (for example, access concentrators) allow a limited
ability to configure the limits. Other switches have fixed limits. If you do not
know the limits, ask the ATM switch vendor.
3. If your ATM switch is handling non-DEFINITY traffic, enter the resource
limits after subtracting the resources used by the non-DEFINITY traffic.
4. If you are using an ATM switch with different limits on different modules or
ports (for example, Lucent Cajun M770):
a. compute the average limits per port to which a DEFINITY port
network is attached.
b. select the port with the most restrictive limitations.
c. enter the system limit as these limits times the number of DEFINITY
port networks attached to that ATM switch.
NOTE:
The more partitioned the limits are, the less accurate are the
results of the spreadsheet.
5. If you answer "yes" to transit traffic, the calculator may or may not be able
to determine feasibility. If it cannot, the feasibility displays as UNKNOWN.

Final notes
The goal is to engineer the network so that in all reasonable applications, you
always run out of DEFINITY time slots before running out of ATM switch
resources. This is required to provide acceptable service to the customer.
These calculations factor in phone calls only. There is no specific
accommodation for the ATM SVC cache, or for special features such as music,
announcements, and group paging. The theory behind using 500 as the number
of timeslots in a port network rather than the real number (484) is to allow for a
normal amount of these special features. If you use multiple music on hold, group
paging, and so forth, you may need special engineering.
This calculator determines that an application is PROBABLY feasible if it can
handle reasonable activity mixes. The three columns in Table 1-7 that have bold
entries define what is meant by reasonable. These tests require that the switch
be able to handle a complete suite of 2-party calls, a complete suite of 3-party
calls, and a mixed suite that involves some calls of each type. For best results,
your application should pass all the constraint tests.
Any ATM switch that processes transit traffic (that is, connections that do not
either originate or terminate on any of the port networks directly attached to it)

ATM switch is more than one. If this is the case, the calculator first attempts to
determine if the application is feasible despite the transit traffic. If it is, it reports
the feasibility as YES or PROBABLY. If not, it reports the feasibility as
Known limits of commonly used ATM switches
Use the limits shown in Table 1-8 to do your own calculations. To make it easier
as you use the calculator, we suggest that you
1. Select and copy the values from the table in the spreadsheet.
2. Select the values on the sample calculation.
3. Select Edit > Paste Special with the transpose option to paste the values
into the calculator.
NOTE:
These limits are the best we could determine at one time. For each switch,
the example shown is generally the best you can do, assuming you bought
the maximum configuration and you administered it optimally for DEFINITY
(which are not necessarily the default settings). Consult the switch vendor
for confirmation of current limits.

This chapter describes the procedures for installing a new DEFINITY ECS
Release 8 ATM-CES The procedure is simple in that you install the DEFINITY ECS
then install the ATM switch and the TN2305/TN2306 interface circuit packs.
Making it an ATM-CES is done administratively (refer to Chapter 5, ‘‘Administering
ATM-PNC and ATM-CES’’).
NOTE:
ATM-CES works only with TN2305/TN2306 ATM interface circuit packs.
Equipment Installation
To prepare for a new DEFINITY ECS ATM-CES installation, you need to install the
DEFINITY ECS first. For instructions on installing DEFINITY ECS, refer to the
following installation books:

‘‘Synchronization Installation and Testing’’ on page 3-3.
Synchronization Installation and
Testing
A DEFINITY ATM-PNC requires network synchronization for DS1 circuit packs not
to slip relative to the LEC/IXC switches. The ATM switch serves as the sync
reference source for the DEFINITY. The ATM switch, in turn, derives primary and
secondary sync. To accomplish this, the most common option is to use
synchronization expanders (splitters).

Connections without synchronization splitters
In some configurations the ATM switches are traced to network clocks through
their SONET/SDH interfaces, not requiring any synchronization splitters.
However, the ATM switch could require a single splitter if only one of the sync
sources is derived from the network.
The ATM switches may obtain their network synchronization as follows:
■
The ATM switch gets its network timing reference from its
SONET/SDH/SDIT interface to that network.
■
Or if the customer wants to use a DS1 source for network synchronization
that also happens to be a DEFINITY ECS switch trunk, then one sync
splitter is necessary to send a copy of that DS1 signal to the ATM switch.
The DS1 circuit pack is only an indirect timing reference for the DEFINITY
ECS switch.
Connections needing synchronization splitters
If the ATM network does not provide a synchronization expander (splitter), then
the ATM configurations may require one that takes a DS1 T1 or E1 signal and
redirects it to the
■
ATM switch(es), depending on configuration and duplication
DEFINITY ECS through the DS1 circuit pack
■
This creates a single synchronization source.
Check the customer’s configuration carefully so that you can

Connect the hardware correctly during installation
■
Properly administer the synchronization plan later (Chapter 5,

Installing and testing the synchronization splitter involves interrupting the DS1
signal provided by the service provider. Even though the DS1 circuit pack should
be down less than 5 minutes, before removing a working T1/E1 span, contact the
service provider. Failure to notify the T1/E1 service provider may result in:
— The service provider looping the T1/E1 span back to the
subscriber.
— A span alarm being detected at the central office and the span
being taken out of service, sending an AIS (blue Alarm) to the
DEFINITY ECS. The synchronization signal is necessary for testing
equipment and connections.
Splitter descriptions
Table 3-2 describes the 4 splitter models and their capabilities. The drawings
show the splitters and their connection points. Figure 3-5 shows a schematic of
the 2 jumper sets and their connections for 401A, 402A, and 403A sync splitters.

The basic process is to
■
■
■
■
■
■
Upgrade DEFINITY ECS to Release 7r (refer to the upgrade book)
Make sure all equipment is on site before the installation
Remove the old TN2238 ATM interface circuit packs
Install the new TN2305/TN2306 ATM interface circuit packs
Connect the fiber cables to the circuit packs
Upgrade to Release 8r software
To upgrade ATM-PNC from Release 6.3r to Release 8r, you must first upgrade
Release 6.3r software to Release 7r software.
To upgrade ATM-PNC from Release 7r to Release 8r, you must install the
TN2305/TN2306 circuit packs before upgrading Release 7r to Release 8r
software.
NOTE:
Although Release 7r software recognizes the old TN2238 circuit pack,
Release 8r software does not.
NOTE:
tape drive with an optical drive.
The following tables have the step-by-step procedures. For critical reliability/ATM
network duplication, perform the steps in Table 4-5, and for standard and high
reliability perform the steps in Table 4-6. In using the commands in the upgrade
tables, type the command and then press Enter.
The critical reliability procedure is call-preserving if the steps are completed in
order and the standby port network is addressed first followed by the active port
network. This process assumes that the ATM switch is not changing.
!
CAUTION:
You must replace the TN2238 circuit pack with the TN2305/TN2306 circuit
pack before upgrading the software to Release 8r.
If for some reason the ATM switch is changing also, it simplifies the cutover
significantly if the new ATM switch inherits the ATM address from its predecessor.

Upgrading ATM-PNC from Release 7r to Release 8r does not require any
additional hardware. The basic process is to upgrade the DEFINITY ECS to
Release 8r first, then upgrade the ATM-PNC. See Chapter 5, ‘‘Administering
ATM-PNC and ATM-CES’’ for information on upgrading through administration.
NOTE:
Upgrading DEFINITY ECS Release 7r to Release 8r requires replacing the
tape drive with an optical drive.

■
SAT—System Administration Terminal
DSA—DEFINITY Site Administration
DNA—DEFINITY Network Administration
The SAT has been the traditional method for accessing DEFINITY; however, it is
no longer being offered or supported. Field technicians can use laptops or
Windows-based PCs to administer the switch.
DSA is a software-only system management tool that runs on personal computer
using Microsoft Windows 95/98/NT 4.0. It is designed for a single user to
administer and monitor DEFINITY switches and voice mail systems. The software
is available on laptops.

5-2
DEFINITY Network Administration (DNA) is a software-only system management
tool based on client-server architecture. It gives multiple administrators the ability
to administer a network of DEFINITY switches and INTUITY Voice Mail systems
simultaneously from different machines.
Although the 3 methods of access present different interfaces, the command
syntax is the same. The screens shown in this section are as they look on a
Release 8r platform through a SAT. Your interface and screen page numbers may
differ.
Acquiring ATM Addresses
Equipment that interfaces with an ATM switch must have a unique 40-digit
(20-byte) ATM address (see Figure 3-1). These 40 characters are divided into
sectors as Table 5-1 shows:
Table 5-1. ATM addressing
Hex digit Length
position
(hexadecimal)
Description
1-26
26
Network prefix that identifies a particular ATM
switch in the network.
27-38
39-40
12
2
End system identifier (ESI) identifies each
end-station connected through an ATM
switch.1
Selector byte is always 0 for DEFINITY ATM
1. The ESI is usually the IEEE Media Access Control (MAC) address programmed into
the end-station device during its manufacture. The MAC address on the
TN2305/TN2306 is located on the MAC address button on the circuit pack (see
Figure 5-1).
In Release 7 or later, the address of the EPN is automatically derived by the local
ATM switch using the address registration procedure defined in the Integrated
address plus the 6-byte ESI, or MAC address, and the 1-byte selector byte of the
corresponding TN2305 or TN2306 board(s) in the EPN to formulate the 20-byte
ATM address(es).
ATM switches can use any of the address formats listed in Table 5-2.
NOTE:
The beginning AFI and the last 2 sectors (ESI, and Selector) in Table 5-2
are all the same length, making it easier to parse the ATM address,
regardless of the format.

Concept
Description
PNC duplication
If you are installing or upgrading a critical reliability system, you must enable
the PNC duplication on the system-parameters customer-options screen
(init password required) before the feature can be used. If it is enabled, you
must further
■ Add pnc-a or pnc-b to command strings to clarify which carrier the ATM
interface circuit pack is in
■ Specify the location of the ATM interface circuit pack serving as the
duplicate
The ATM interface circuit pack in the A carrier must be in the same port
network as the B carrier. If not, an alarm is issued. You need not administer
ATM interface circuit packs serving as backups to each other with the same
parameters.
Fiber links
You do not need to administer fiber links for ATM-PNC. Information on the
ATM circuit pack screen identifies which packs are used for PNC
(endpoint-1), and endpoint-2 is administered on the ATM switch.
Remote switch
administration
A remote switch connected with a permanent virtual circuit (PVC). The
DEFINITY system recognizes the remote switch as a node with compatible
circuit parameters at the other end of an emulated circuit.
You can connect a remote switch to the DEFINITY with one or more
CES-emulated circuits. In such a case, the emulated circuits remain
discrete.
Synchronization
PNC—All synchronization is derived from the ATM switch providing port
connectivity. The ATM switch obtains synchronization from either a sync
splitter attached to one or two DS1 cards or from the ATM network.
CES—Synchronization is derived the same way it is in a non-ATM-PNC or
ATM-PNC environment, whichever applies.

Both procedures are in Table 5-8, under ‘‘ATM-CES administration
procedure’’ on page 5-12.
■
■
■
■
Uses ATM emulated circuits instead of physical T1/E1 tie-trunks out to the
ATM network.
Uses up to 8 signaling groups per TN2305/TN2306 to create virtual
trunking.
Uses bearer (B) and signaling (D) channels, similar to ISDN facilities but
does not support nonfacility associated signaling (NFAS).
Uses channels inside each signaling group, which appear as if they were
ports on the TN2305/TN2306 circuit pack. Hereafter, these are referred to
as ports.
■
■
Uses constant bit-rate (CBR) signalling over permanent virtual
connections (PVCs).
Has a transparent DEFINITY feature set to other locations through
narrowband QSIG (N-QSIG) or distributed communications system over
ISDN-PRI (DCS+)
NOTE:
do not support DCS, only DCS+.

Trunk groups
At least one trunk group is typically created for each remote switch with these
attributes (see Screen 5-8):
■ Group Type field is isdn
■ Carrier medium field is atm
■ Dial Access? field is always n
■
TN2305/TN2306 may have Trunk Access Codes (TAC), but these are for
reporting purposes only and cannot be dialed.
■
CDR records for ATM trunk calls are maintained.
NOTE:
Release 7 introduced 3-digit port numbers for administering a CES
trunk, and CMS cannot read the old 2-digit numbers. Release 8 CMS
software can read both the 2- and 3-digit port numbers.
■
■
A trunk group may include ports from more than one of the ATM circuit
packs in the system. This enables same module preference, the feature
that gives preference to outgoing trunks on the same port network as the
originator.
ATM trunk groups can only contain ports on ATM boards, and ports on
ATM boards cannot be assigned to non-ATM trunk groups.
ATM-CES trunk board
When administered as a trunk board, the TN2305/TN2306 can have up to 8 ATM
signaling groups with up to 30 members per signaling group over an
OC-3/STM-1 connection. Although the ATM board does not have physical ports,

■
Each of the 248 ports in the ATM trunk group are either B-channels or
D-channels.
■
Each B-channel has an associated maintenance object with a very simple
maintenance strategy. This is done so that any of the virtual ports on a
single ATM interface circuit pack can be members of different trunk
groups. When a trunk group is busied out, only those ports in that trunk
group are taken out of service. Because all ports associated with a single
D-channel follow the same PVC, you cannot test them individually.

SVC cache
DEFINITY ATM software maintains a cache of inter-port-network connections
(SVCs), with the preference given to those SVCs with the longest setup times. All
cached interconnections are aged to ensure that a large number of them are not
kept during nearly idle periods.
You can administer the setup time thresholds, cache holding times, and total
cache size, which can mitigate the effects of long interconnection setup delays.
The change atm svc-cache command (Screen 5-15) is restricted to init, inads,
and craft logins.

Gain/Loss adjustments
Gain and loss are administrable. Calls between a digital (BRI or DCP) phone
(6400 and 8400 series) and an analog trunk port require adjustments to the
default gain/loss settings to prevent distortion. Use the procedure (Table 5-12) to
administer digital phones on ATM-PNC DEFINITY ECSs.

Be aware that customers may use other ports on the ATM switch for
applications unrelated to DEFINITY (LAN traffic or multimedia
applications, for examples).
These other applications may manifest themselves in the output of
the troubleshooting commands you run on the ATM switch.
DEFINITY port networks must be identified by their ATM switch port
numbers.
NOTE:
The following examples show DEFINITY port networks
connected to ATM switch ports A1.1 and A1.2.
2. Does the TN2305/TN2306’s YELLOW LED flash 100 ms on and 100 ms off,
indicating a loss of signal on the fiber? Recall that the TN2305/TN2306
detects continuity problems with either the transmit (bottom) or the receive
(top) fibers.
If the fiber shows a loss of signal, refer to the “Fiber Fault Isolation
Procedure” in DEFINITY ECS Maintenance for R8r.
3. Is the ATM switch port’s LED indicating a loss of signal on the fiber? Note
that the ATM switch may detect continuity problems only with the receive
fiber; the state of the transmit fiber might not be detected.
4. Refer to your ATM switch’s quick reference guide for troubleshooting
commands.
Possible causes.
Check the following list for possible causes.
■
■
■
The fiber is disconnected from the ATM switch and/or the TN2305/TN2306
circuit pack.
The transmit and receive fibers are swapped at the ATM switch or the
TN2305/TN2306 circuit pack (but not both).
There is a break in the fiber.
■
The TN2305/TN2306 is not transmitting a carrier (not inserted, not
powered, or not administered). See the ATM-TRK maintenance
object in one of the following books:

■
The ATM switch does not recognize that a port circuit pack is in the slot.
You may need to re-administer the ATM switch port boards. Refer to your
ATM switch’s quick reference guide for further information.
Recommended Action.
1. Plug in, swap, repair, or replace the fiber as necessary.
2. Verify that the port circuit pack is completely inserted.
SONET/SDH layer
Are SONET/SDH frames reaching the ATM switch?
Is the ATM switch port’s LED indicating no cell traffic?
■
Check the transmit and receive cell count fields. Each field’s values
should be increasing if the TN2305/TN2306 is actively sending and
receiving cells to and from the ATM switch.
■
■
Check for SONET/SDH layer alarms, LOP, LOF, LOS, and so on.
If neither field is increasing, the ATM switch port may be down. Verify that
the admin status is up.
■
■
If the receive cell count is increasing but the transmit cell count is not
increasing, this may be because the port was administered with no UNI
signaling. Ensure that signaling is UNI3.1.
Although the error counters may not be zero, they should not be large
either compared with the receive and transmit cell counters. If the
counters are large and increasing, check the fiber integrity. Make sure the
fiber pairs are securely plugged into both the TN2305/TN2306 circuit pack
and the ATM switch.
■
If the fiber has been pulled and reinserted as part of fault diagnosis, the
nonzero loss of signal error counter may be correct.
Call processing (CaPro) Layer
Are control channels being established from the PPN to the EPN?
Diagnostics.
■
Do you get a dial tone on a set on the port network in question?
Can you ring a set on the EPN dialing from the PPN and vice-versa?

2. On the ATM switch console, look at the switch circuit.
The VBRnrt (Variable Bit Rate) virtual circuits between the ATM switch PPN
and EPN ports are used for signaling between the PPN and each EPN.
■
These are established once when initialized under control of DEFINITY
Call Processing. They represent the ATM Control Link (ACL) and
Expansion Archangel Link (EAL).
■
■
VBRnrt virtual circuits are also used for ISDN channels between DEFINITY
port networks.
Other VBRnrt virtual circuits may exist between ATM switch ports that are
not associated with DEFINITY port networks. A common use of VBRnrt
circuits is multimedia and video-conferencing systems.
Are talk paths being established between port networks?
Diagnostics.
■
Can you talk both ways on a set on one port network dialed from another
port network and vice versa?
— The CBR (Constant Bit Rate) virtual circuits (VCs) between ATM
switch PPN port and ATM switch EPN port are used for talk paths
between port networks (PPN to EPN, EPN to PPN, or EPN to EPN).
— They are established when calls are first setup between port
networks. Each virtual circuit represents one party of a complete
multiparty talk path.

— These virtual circuits may persist beyond the duration of a phone
call. The DEFINITY Call Processing software saves virtual circuits
for a few seconds after the end stations have hung up in case the
VC can be used again for another call between the same two port
networks.
— There may be other CBR virtual circuits between ATM switch ports
that are not associated with DEFINITY port networks. A common
CBR application is Circuit Emulation, in which T-1, T-3, and so forth
circuits are carried over ATM.
Unusual ATM trouble conditions
A few failure modes in the DEFINITY ECS/ATM switch combination are
particularly difficult to diagnose. One example might be that you cannot make a
completely successful call even though most indications from DEFINITY ECS and
the ATM switch look good.
This section documents some hints and clues that may help diagnose the
following failure modes:
■
Incorrectly typed or omitted EPN route or end system identifier (ATM
switch)
■
Swapped routes, end system identifiers, or fiber between a PPN and an
EPN
Incorrectly typed or omitted EPN route or
end system identifier (ATM switch)
Symptoms
Talk paths are one-way, from the PPN to the EPN: you can hear tones from the
PPN end station to the EPN end station but not vice versa. Because the signaling
channels are bidirectional virtual circuits (VCs) established from the PPN to the
EPN, these can be routed correctly and come up just fine. Talk paths are two
unidirectional virtual circuits, so a single call has one VC from the PPN to the EPN
(which is routed correctly) and one VC from the EPN to the PPN (which cannot be
routed).
Diagnostics
1. At the ATM switch, check the ATM addresses.
2. Look for a cause code 3 (No route to destination).
Action
1. Correct the ATM address translations in the ATM switch.

Swapped routes, end system identifiers, or fiber
between a PPN and an EPN
Symptoms
■
■
An incorrectly connected EPN TN2305/TN2306 circuit pack is not
completely inserted.
Dial tone is present on end stations on the PPN and on correctly
connected EPNs, but no dial tone is present on the affected EPN end
stations.
■
Calls cannot be made between the PPN and the correctly connected
EPNs because talk paths cannot be routed correctly.
Diagnostics
1. Check to see if the ATM switch shows VBR control channels from the ATM
switch port intended for the incorrectly connected EPN (but actually
connected logically or physically to the PPN) that should not exist.
Action
1. Correct the ATM addresses (or swap fibers) on the ATM switch between
the incorrectly connected PPN and EPN.

TN2305/TN2306 circuit pack—Checks LED status, circuit pack insertion,
and demand tests
ATM signaling architecture—Checks the interoperability between the
DEFINITY ECS switch and the ATM switch
Because Lucent offers a variety of ATM switches, this discussion suggests
general rather than specific diagnostics.
Physical connections
Has the ATM switch been installed and configured correctly?
Diagnostics
■
Is the ATM switch powered up?
■
If you are administering the ATM switch through a locally attached
console, is there a local console terminal connected to the console port on
the ATM switch processor circuit pack with the correctly pinned RS232
serial cable?
■
If you are administering the ATM switch through telnet over the Ethernet, is
there an Ethernet drop plugged into the Ethernet port on the ATM switch
processor board? (Note that a few ATM switch commands are only
permitted over the local console terminal.)

■
■
■
Are any ATM switch FAULT LEDs lit?
Are the remaining ATM switch LEDs in a normal state?
Can you log into the ATM switch console using the diagnostic account
from the local console terminal or through telnet? If so, check the system
status
a. If the customer is providing an Ethernet connection to the ATM
switch, does the Ethernet IP addressfield have the
customer-provided Internet address?
NOTE:
You might not be able to administer the ATM switch through a
telnet connection over the Ethernet, but if you are able to,
make sure the Ethernet address is correct.
b. If the customer is providing an Ethernet connection to the ATM
switch, does the Ethernet IP maskfield have the
customer-provided mask (typically something like
255.255.255.0, although other values are valid)?
c. If the customer is providing an Ethernet connection to the ATM

d. If the customer is providing an Ethernet connection to the ATM
switch and intends to upload to or download from a TFTP server,
does the TFTP serverfield have the customer-provided Internet

Physical layer
Is there an optical signal between the TN2305/TN2306 and the ATM switch?
1. Identify the OC-3/STM-1 ports on the ATM switch that have DEFINITY port
networks attached.
■
Be aware that customers may use other ports on the ATM switch for
applications unrelated to DEFINITY (LAN traffic or multimedia
applications, for examples).
■
These other applications may manifest themselves in the output of
the troubleshooting commands you run on the ATM switch.
DEFINITY port networks must be identified by their ATM switch port
numbers.
NOTE:
The following examples show DEFINITY port networks
connected to ATM switch ports A1.1 and A1.2.
1. Does the TN2305/TN2306’s YELLOW LED flash 100 ms on and 100 ms off,
indicating a loss of signal on the fiber? Recall that the TN2305/TN2306
detects continuity problems with either the transmit (bottom) or the receive
(top) fibers.
If the fiber shows a loss of signal, refer to the “Fiber Fault Isolation
Procedure” in DEFINITY ECS Maintenance for R8r.
2. Is the ATM switch port’s LED indicating a loss of signal on the fiber? Note
that the ATM switch may detect continuity problems only with the receive
fiber; the state of the transmit fiber might not be detected.
3. Refer to your ATM switch’s quick reference guide for troubleshooting
commands.
Possible causes.
Check the following list for possible causes.
■
■
The fiber is disconnected from the ATM switch and/or the TN2305/TN2306
circuit pack.
The transmit and receive fibers are swapped at the ATM switch or the
TN2305/TN2306 circuit pack (but not both).
■
■
There is a break in the fiber.
The TN2305/TN2306 is not transmitting a carrier (not inserted, not
powered, or not administered). See the ATM-EI or ATM-TRK maintenance
objects in DEFINITY ECS Maintenance for R8r.
■
Hardware safety interlocks on optical transceivers may cut transmitter
power if no carrier is received, so lack of a receive carrier could indicate a
transmitter problem at the same end.

■
The ATM switch does not recognize that a port circuit pack is in the slot.
You may need to re-administer the ATM switch port boards. Refer to your
ATM switch’s quick reference guide for further information.
Recommended Action.
1. Plug in, swap, repair, or replace the fiber as necessary.
2. Verify that the port circuit pack is completely inserted.
SONET/SDH layer
Are SONET/SDH frames reaching the ATM switch?
Is the ATM switch port’s LED indicating no cell traffic?
■
Check the transmit and receive cell count fields. Each field’s values
should be increasing if the TN2305/TN2306 is actively sending and
receiving cells to and from the ATM switch.
■
■
Check for SONET/SDH layer alarms, LOP, LUF, and so on.
If neither field is increasing, the ATM switch port may be down. Verify that
the admin status is up.
■
■
If the receive cell count is increasing but the transmit cell count is not
increasing, this may be because the port was administered with no UNI
signaling. Ensure that signaling is UNI3.1.
Although the error counters may not be zero, they should not be large
either compared with the receive and transmit cell counters. If the
counters are large and increasing, check the fiber integrity. Make sure the
fiber pairs are securely plugged into both the TN2305/TN2306 circuit pack
and the ATM switch.
■
If the fiber has been pulled and reinserted as part of fault diagnosis, the
nonzero loss of signal error counter may be correct.
Q.SAAL (data link) layer
Are ATM signaling messages reaching the ATM switch Call Control?
NOTE:
If the TN2305/TN2306 circuit pack is not connected to the ATM switch at
the Q.SAAL protocol layer, then no report is displayed.
1. If the port of interest is not configured for UNI signaling, then the port was
administered for no UNI signaling. Verify that signaling is UNI3.1.
2. If the port of interest was administered for UNI3.0 signaling, verify that
signaling is UNI3.1.
3. Check to see if the TN2305/TN2306 circuit pack is actively sending and
receiving Q.SAAL Protocol Data Units with the ATM switch.

Q.93B (network) layer
Are connection requests being received by ATM switch call control?
NOTE:
If there is no connection between the TN2305/TN2306 circuit pack
and the ATM switch at the Q.93B protocol layer, then no report
displays.
1. Check the port of interest. If it is not configured for UNI signaling, then the
port was administered for no UNI signaling. Verify that signaling is UNI3.1
2. The connect, setup, and release message counters should be a nonzero
number if the ATM switch is handling Q.93B protocol layer messages sent
by the PPN and EPN. They may not increase during troubleshooting
unless calls are being made because the PPN initially sets up control
connections to the PPN and then sets up talk path connections as
needed.
3. Check to see if connections are being rejected. The error may be on the
versa.
4. Type display errors and press Enter.
5. Set the Error Listfield to errors and Categoryfield to PNC on the
input screen (Screen 6-14) and press Enter to display any cause codes
(see Table 6-11) returned from the ATM network to a TN2305/TN2306
circuit pack on the PPN (and to a TN2305/TN2306 circuit pack on an
EPN). This is successful only if the links between the PPN and the EPN
remain up so that the message from the EPN is logged.

ATM call control
Are ATM signaling connections being setup to ATM switch Call Control?
The UBR virtual circuits between the ATM switch PPN port and ATM switch port
and between the EPN port and ATM switch port are ATM signaling channels
between the port network and the ATM switch. They are used to request
connection setups and releases to other end points such as another port
network. These are established by each TN2305/TN2306 when it comes up,
independent of DEFINITY Call Processing.
Other UBR virtual circuits may exist between ATM switch ports that are not
associated with DEFINITY port networks and may be signaling channels for other
applications (for example, data network traffic).

Are talk paths being established between port networks?
Diagnostics.
■
Can you talk both ways on a set on one port network dialed from another
port network and vice versa?
— The CBR (Constant Bit Rate) virtual circuits (VCs) between ATM
switch PPN port and ATM switch EPN port are used for talk paths
between port networks (PPN to EPN, EPN to PPN, or EPN to EPN).
— They are established when calls are first setup between port
networks. Each virtual circuit represents one party of a complete
multiparty talk path.
— These virtual circuits may persist beyond the duration of a phone
call. The DEFINITY Call Processing software saves virtual circuits
for a few seconds after the end stations have hung up in case the
VC can be used again for another call between the same two port
networks. Also, check 3-way conference calling across 3 port
networks.
— There may be other CBR virtual circuits between ATM switch ports
that are not associated with DEFINITY port networks. A common
CBR application is Circuit Emulation, in which T-1, T-3, and so forth
circuits are carried over ATM.
Unusual ATM trouble conditions
A few failure modes in the DEFINITY ECS/ATM switch combination are
particularly difficult to diagnose. One example might be that you cannot make a
completely successful call even though most indications from DEFINITY ECS and
the ATM switch look good.
This section documents some hints and clues that may help diagnose the
following failure modes:

Incorrectly typed or omitted EPN route or
end system identifier (ATM switch)
Symptoms
Talk paths are one-way, from the PPN to the EPN: you can hear tones from the
PPN end station to the EPN end station but not vice versa. Because the signaling
channels are bidirectional virtual circuits (VCs) established from the PPN to the
EPN, these can be routed correctly and come up just fine. Talk paths are two
unidirectional virtual circuits, so a single call has one VC from the PPN to the EPN
(which is routed correctly) and one VC from the EPN to the PPN (which cannot be
routed).
Diagnostics
1. At the ATM switch, check the ATM addresses.
2. Look for a cause code 3 (No route to destination).
Action
1. Correct the ATM address translations in the ATM switch.
Swapped routes, end system identifiers, or fiber

Symptoms
■
■
An incorrectly connected EPN TN2305/TN2306 circuit pack is not
completely inserted.
Dial tone is present on end stations on the PPN and on correctly
connected EPNs, but no dial tone is present on the affected EPN end
stations.
■
Calls cannot be made between the PPN and the correctly connected
EPNs because talk paths cannot be routed correctly.
Diagnostics
1. Check to see if the ATM switch shows VBR control channels from the ATM
switch port intended for the incorrectly connected EPN (but actually
connected logically or physically to the PPN) that should not exist.
Action
1. Correct the ATM addresses (or swap fibers) on the ATM switch between
the incorrectly connected PPN and EPN.

The PPN establishes links to what it thinks is the active TN2305/TN2306
circuit pack on the EPN.
As normal, it reboots this TN2305/TN2306 circuit pack, and when
complete, it resets the EPN. When this happens, the active (instead of the
standby) TN2305/TN2306 circuit pack reboots, dropping the links.
■
To recover, the PPN re-establishes links to what it thinks is the active
TN2305/TN2306 circuit pack and the cycle repeats indefinitely.
Diagnostics
1. Type status pnc and press Enter. The screen shows both the A-side and

commands
Wide-area networks (WAN), especially those constructed as an internet using
public network facilities, may take inter-PN connectivity to the edge of
acceptable performance. The switch may experience delays, blockages, or
connection losses because of circumstances beyond the control of switch
management. Variations in performance may be expected during periods of high
traffic.
If ATM-PNC is enabled (change system-parameters customer-options), 2
commands become available:
■
change/display atm pnc-pairs lets you get inter-port-network
measurements for up to 10 ordered pairs of port networks
■
list measurements atm pnc-latency reports data about ATM cell latency
and connection times.
In both of these commands, you must supply the following information:
■
■
■
■
the number of connections requested,
the average connection setup time in milliseconds,
the number of ATM network setup requests required, and
the average setup time for the ATM connections.
Separate sets of measurements are available for the A and B sides in critical
reliability systems.

Conserving ATM bandwidth
Port Networks in a DEFINITY ATM-PNC configuration, when used with the Lucent
access concentrators or other ATM switches interfacing to
bandwidth-constricted or congested facilities, can incur contention for
bandwidth, resulting in failed call completions. Figure 6-4 represents a DEFINITY

network occurs. In such cases, SVC setups requested by DEFINITY can be
denied by the ATM network and associated components, and calls are not
completed.
In this section, a failed SVC setup means that the ATM network has actively
rejected the request. A delayed SVC setup means that the SVC setup exceeded
a time threshold, specified in milliseconds (ms).
Performance indicators of both failed and delayed SVC setups:
■
The called party may hear ringing, take the receiver off-hook, and hear
nothing. The called party may eventually receive a delayed call, but never
receives a failed call.
■
■
If the call was delayed, the calling party hears silence if one of the SVCs is
not up or hears the called party if it is up.
If the call is never completed, the caller eventually hangs up without
knowing why the call was not completed.

This field specifies the percentage of setup events for a
path to become impaired. That is, if the percentage of
setup events for a given path meets or exceeds this
administered value, then it becomes impaired (see
example below). An alarm is raised against an ATM-IMP
when one or more paths originating from that ATM-IMP
become impaired. [Values 1 to 20, default is 4]
This field specifies the percentage of setup events for a
path to come out of the impaired state. That is, if the
percentage of setup events for an impaired path meets or
drops below this administered value, then it is no longer
impaired (see example below). An alarm is retired when no
more impaired paths are originating from that ATM-IMP.

The maximum number of milliseconds allowed for an SVC
connection to be completed before being counted as
delayed. [Values 250 to 20,000, default is 1000]
Deny Calls Using
Impaired Paths?
This field specifies whether to deny calls that use
connections over impaired paths. If the option is y, then
calls that require a new SVC on an impaired path on the
active PNC are not completed. If the option is n, then those
calls are treated according to current administered
parameters for ATM PNC. [Default is n]
Example:
If the value for Activation (%) is 5, then the value for Deactivation (%) can be 0, 1,

Operation
Description
Station alerting
When a call is offered to a station, an inter-PN connection is
initiated and the phone rings. This procedure applies to
calls to stations, data modules, and attendant consoles.
When the user answers, the station should be connected
before the user says “hello.”
Trunk seizure
Trunk seizure happens after an outgoing call is submitted
to an outgoing trunk port, followed by address outpulsing.
Seizure and address outpulsing do not require an
established talk path to the trunk. If the talk path to or from
the trunk is delayed for several seconds and the call was
dialed instantly through abbreviated dialing, some initial
call progress feedback might be missed and, perhaps,
some information from the answering party.
Connection setup times of as much as 1-2 s can be
covered by seizure/outpulsing, but longer setup times
require postponing seizure until the inter-PN connection is
established.
Recorded announcements When an announcement is connected, it requests playback
as soon as possible. The switch delays playing back an
announcement until at least one inter-port-network
connection, if needed, is established.
The barge-in announcements, which the caller joins in
progress, do not require this delay.

Time of Day considerations
Tab l e B -3 shows the time-of-day impacts on users and administrators. In the
Group column:
■
User-visible means that times are visible and/or manipulated by the users.
■
System management means that times are visible to, used by, and set by
the system administrator or other switch management.

User-visible
The user is able to specify and receive a wakeup
call at the correct local time.
Call Detail Recording System
management
Times recorded may have to be matched against
times reported by public network service providers
(which may be dependent on the locations of trunk
groups). Two kinds of changes:
■ Automatic changes are set in software to
occur at 2 AM, for example.
■ Manual changes are still possible
Time-of-Day routing
System
management
Times are derived from time-of-day considerations
based on the location(s) of various outgoing
trunks. For example, a time-of-day routing change
may take place at 5:00 PM EST because calls
entering the public network through a New York
trunk group receive reduced rates. Another
change may occur at 5:00 PM PST because trunks
in Los Angeles now provide reduced rates. Some
or all of these times may be subject to daylight
savings time changes.
Malicious Call Trace
AUDIX
System
management
Recorded time may need to be converted to
user-perceived time. Because this feature is
invoked infrequently, manual conversion is
acceptable.
User-visible
AUDIX maintains its own time (including daylight
savings) and is unaffected by switch
administration. Depending on the number of DCS
links available, it is possible to provide a different
AUDIX switch for each time zone (or each
location), with the AUDIX clock set to match.

Delay Interactions
Delays in ATM cell delivery affects the ATM-PNC or ATM-CES features and
functionality listed in Tab le B-5.
Additionally, WAN-PNC configurations (more than one ATM switch) require
additional delay considerations:
1. Setting up an SVC through the PNC can be delayed by as much as 7 s,
similar to an ISDN trunk.
2. An SVC request can fail, and this failure may not be received for several
seconds.
3. Paths through the PNC are not free (however, tariffing of these resources is
highly variable).
Table B-5. ATM delay interactions
Feature
Description
POTS (plain old telephone
service)
Lets in normal point-to-point calls the terminating side does not ring
until an SVC is established through the WAN.
AAR (Automatic Alternate
Routing)
Route calls based on the preferred (normally the least expensive)
route available at the time the call is placed.
ARS (Automatic Route
Selection)
AAR and ARS Overlap
Sending
Determines that if the call is to be routed to another switch over a
trunk with ISDN overlap sending, the system seizes the outgoing
ISDN trunk and starts sending digits while DEFINITY ECS continues
to collect (receive) the remaining incoming digits.

This feature is affected by SVC setup delays and failures.
VDN of Origin
Announcement
Provides agents with a short message about a caller’s city of origin or
requested service based on the VDN used to process the call. This
feature is affected by SVC setup delays and failures.
Visually Impaired
Attendant Service
Allows a visually impaired attendant to listen to voiced information
about each button in Inspect mode. This feature is affected by SVC
setup delays and failures.
Voice Response
Integration
Integrates Call Vectoring with the capabilities of voice response units
(VRUs) such as the Lucent Technologies CONVERSANT Voice
Information System (CVIS). This feature is affected by SVC setup
delays and failures.

Provides the ability to dedicate 2 or more ISDN-PRI B-channels or
DS0 endpoints for applications that require large bandwidth. This
feature is affected by SVC setup delays and failures.
World-Class Tone
Detection
Allows DEFINITY ECS to identify and handle different types of
call-progress tones. Affected by delays and failures if the call needs
to go to another EPN for the tone detector.
World-Class Tone
Generation
Allows you to define call-progress tones. Affected by delays and
failures if the call needs to go to another EPN for the tone generator.
ATM Feature Interactions
The following sections summarize the effects of ATM-WAN PNC on various
features because of:
1. Location assignments in a widely distributed switch
2. Cell delivery delays and race conditions that occur on the ATM-WAN.
The features affected by these conditions are listed in Tab le B -6.

X
If a call goes to AUDIX, and the
assigned AUDIX is far across the
WAN, a race condition can exist
between alerting with answer by
AUDIX, and establishment of an
inter-port-network connection
through the ATM WAN. If the WAN
loses, the AUDIX announcement
could be clipped or lost.
Avoid this problem by
providing local AUDIX
systems, each located
near its subscriber. If the
switch spans multiple time
zones, a separate AUDIX
for each time zone is also
desirable to provide the
correct timestamps for
recorded messages.
