2. Basic Configuration
The menu structure and selections, and the features and functions of the
FrameSaver unit, are changed based upon the type of service being used.
Install screens.
Table 2-1. Easy Install Configuration Options (1 of 7)
Service Type
Possible Settings: Frame Relay, Leased Line, PPP
Default Setting: [Depends on model]
Specifies the type of service to which the unit is to be connected.
Frame Relay – Frame Relay-aware mode, for connection to a frame relay service. This is
the default operational mode, and it is used to configure the FrameSaver unit in frame
relay mode so that frame relay parameters and SLV functionality can be set up.
If a 9123 unit is set to Leased Line, then changed to Frame Relay, Time Slot Discovery is
temporarily suspended until LMI communication is reestablished, and all frame
relay-related configuration options previously set up are restored, except for the Sync
Data Port Assignments. In this case, all port assignments set to S1Port-1 are converted to
FrameRly1 assignments on the Frame Relay Network 1 Assignment timeslot assignment
screen.
Leased Line – Leased-line mode, for connection to a standard leased-line service. This
mode provides a simple and straightforward screen to guide the installer during initial
installation, and to set up remote access to the unit.
When operating in leased-line mode, no frame relay-related statuses, performance
statistics, tests, configuration options, or control features are available; only physical layer
functions are available.
If the unit is set to Frame Relay then changed to Leased Line, all frame relay-related
screens and features are filtered so they are transparent to the user. All frame relay links,
DLCIs. and PVCs are preserved. For 9123 units, all Frame Relay Network 1 FrameRly1
time slot assignments are converted to S1Port-1 on the Sync Data Port Assignments
screen.
PPP – Point-to-Point Protocol mode. A single PPP circuit exists between Port1 and Net1.
Changing to or from PPP mode causes a reset.

2. Basic Configuration
Using RIP with FrameSaver SLV CSU/DSUs
Using the system’s standard Routing Information Protocol (RIP) feature, routing
information is passed to the router over the management PVC, so the router can
learn routes to FrameSaver devices. Node IP information should be set up (see
Procedure
To set up your router and FrameSaver SLV CSU/DSU so that the router can learn
routes to FrameSaver devices:
1. Configure the router to receive RIP.
For example, if using a Cisco router, you would use the commands
config-t, router RIP, int serialx, IP RIP Receive version 1,
then ctl-z WR.
2. Create a Standard DLCI for the user data port.
Configuration→Data Ports→DLCI Records
3. Create a Management PVC using the user data port DLCI just configured.

2. Basic Configuration
Selecting a Frame Relay Discovery Mode
When a Frame Relay Discovery Mode is active, the FrameSaver unit “discovers”
network DLCIs from the network LMI status response message. It configures a
network DLCI and a user data port DLCI, and automatically connects them to
create a PVC.
Main Menu→Auto-Configuration→Frame Relay Discovery Mode
Automatically configured network DLCIs are multiplexed, and each automatically
configured port DLCI carries the same DLCI Number as its corresponding network
DLCI. These are the same DLCI numbers that would have been available had the
FrameSaver unit not been inserted in the link, between your equipment and the
network.
NOTE:
A local Management PVC (e.g., the PVC between the router and the
FrameSaver unit’s user data port) must be configured manually.
The following will occur when a Frame Relay Discovery Mode is selected:
Discovery Mode
Configuration Description
1MPort
Auto-configuration is enabled on Port-1.
A management DLCI is configured.
A multiplexed network DLCI containing two embedded
DLCIs (EDLCIs) is configured for Port-1 user data and

A PVC connection is configured between the network
and port DLCIs.
1Port
Auto-configuration is enabled on Port-1.
No management DLCI is configured.
A multiplexed network DLCI is configured for Port-1 user
data.
A PVC connection is configured between the network

2. Basic Configuration
Discovery Mode
Configuration Description
NetOnly
Auto-configuration of a network DLCI only; no Port-1 or
PVC connections are configured.
No Port-1, PVC connection, or management DLCI is
configured.
Disable
No frame relay discovery or automatic configuration
takes place.
The FrameSaver unit will be configured manually.
NOTE:
If the default setting (1MPort or 1PPort) is not the setting required for your
application, change the Frame Relay Discovery Mode before connecting the
network cable or editing discovered option settings. Otherwise, the
FrameSaver unit will start discovering DLCIs as soon as it powers up.
If this occurs, you can recover by deleting the discovered DLCIs. If only a local
management PVC between the router and the FrameSaver unit has been
configured, simply select the desired Frame Relay Discovery Mode and Save
the change.
The default discovery mode, depending on model, is 1MPort or 1PPort.
When 1MPort mode is active, the unit creates for each DLCI discovered on the
network a multiplexed network interface DLCI (which contains two EDLCIs: one for
Port-1 data and the other for management), a standard Port-1 DLCI (with the
same number as the network interface DLCI), and a Management PVC, then
cross-connects them. When LMI is active on the network interface and PVC status
information (with provisioned DLCI numbers) is next received from the network,
the unit automatically saves the settings to the Current Configuration area.
When 1PPort mode is active, the unit uses the Network DLCI values obtained from
the Network LMI status response message to automatically configure for each
DLCI a corresponding DLCI for Port 1 having the same numeric value as the
Network DLCI, and automatically cross connects them. The DLCIs created on the
network side are IP Enabled (not standard or multiplexed) DLCIs. In addition,
payload management is configured for the network DLCI and assigned the Node
IP Address.
Configuration options set by selecting a discovery mode can be manually
modified, refined, or deleted at any time using the Configuration menus. No
previously discovered and configured DLCIs or cross-connections will be removed
unless authorized or Automatic Circuit Removal is enabled (see Automatically
according to the current Frame Relay Discovery Mode setting. Selecting or
changing the setting will not affect IP Addresses or Subnet Masks.
NOTE:
When auto-configuration creates a multiplexed DLCI, but a standard DLCI is
needed, change the DLCI to standard from the network DLCI Records screen:

prompt appears. No is the default for this prompt.
n
If Yes (y) is entered, the Delete All DLCIs and PVC Connections?
prompt appears. No is the default for this prompt.
— If Yes is entered, all multiplexed DLCIs and PVC Connections are deleted,
except for Management PVCs with the user data port as the primary
destination and the Management PVC that is designated as TS
Management Link.
— If No is entered, previously discovered and auto-configured option settings
will not be removed, but configuration updates due to LMI response
messages are performed according to the just saved mode setting.
n
If No (n) is entered, or if you exit the screen without responding to the prompt,
no Auto-Configuration updates are performed and updates due to LMI
response messages are performed according to the previously saved setting.
Automatically Removing a Circuit
Using the automatic circuit removal feature, which comes enabled, network DLCIs
and PVCs can be automatically removed from the unit’s configuration when the
network service provider no longer supports them. Automatic deletion is based
upon information from a LMI full status response on an active frame relay link.
When this feature is set to:
n
Enable – The following will be automatically removed from the unit’s
configuration:
— Unsupported network DLCIs and PVC connections that include
multiplexed network DLCIs.
— Standard network DLCIs that are Payload Managed or IP Enabled.
— Unsupported standard network DLCIs that are not configured as the
primary destination in a management PVC.
— Non-management PVCs in which unsupported standard network DLCIs
are included.
— DLCIs not included in three consecutive LMI full status response
messages.
— LMI status responses that indicate a Deleted status for the DLCI.
All configured options relating to the deleted circuits are also deleted and they
revert to their default settings.
A DLCI will not be deleted if the physical interface or frame relay link is down,
or if the DLCI is used for the TS Management Link.
n
Disable – Unused network DLCIs, PVC connections, and management PVCs
must be manually removed.
If the model has ISDN backup capability, ISDN Link Profiles associated with
the deleted records and alternate destinations will be deleted, as well.

LMI Behavior (continued)
Net1-FR1_Follows_Port-1 – Brings LMI down on the network interface when LMI on
Port-1 goes down, disabling the network interface and deasserting its control leads. When
LMI on Port-1 comes back up, the network interface is reenabled. The LMI state on the
network interface has no effect on the LMI state on Port-1. That is, the network interface’s
LMI follows Port-1’s LMI. Used at central sites, this setting is useful when the remote site
router on the other end of the PVC connection can initiate recovery via a redundant
central site when there is a catastrophic central site LAN or router failure. Not
recommended for NSPs.
Net1-FR1_Follows_Port-2 – Reacts like the Net1-FR1_Follows_Port-1 selection, but for
Port-2 instead.
Rtr-S0_Follows_Port-1 – Brings LMI down on the network interface when LMI on Rtr-S0
goes down, disabling the network interface and deasserting its control leads. When LMI
on Rtr-S0 comes back up, the network interface is reenabled. The LMI state on the
network interface has no effect on the LMI state on Rtr-S0. That is, the network interface’s
LMI follows Rtr-S0’s LMI.
Port-1_Follows_Net1-FR1 – Brings LMI down on Port-1 when LMI on the network
interface goes down, disabling Port 1 and deasserting its control leads. When LMI on the
network interface comes back up, Port-1 is reenabled and its control leads are reasserted.
The LMI state on Port-1 has no effect on the LMI state on the network interface. That is,
Port-1’s LMI follows the network interface’s LMI. This setting is useful if the router
connected to Port-1 is used to initiate recovery when network failures are detected.
Port-2_Follows_Net1-FR1 – Reacts like the Port-1_Follows_Net1-FR1 selection, but for
Port-2 instead.
Rtr-S0_Follows_Net1-FR1 – Brings LMI down on Rtr-S0 when LMI on the network
interface goes down, disabling Rtr-S0. When LMI on the network interface comes back
up, Rtr-S0 is reenabled. The LMI state on Rtr-S0 has no effect on the LMI state on the
network interface. That is, Rtr-S0’s LMI follows the network interface’s LMI.
All_Ports_Follow_Net1-FR1 – Brings LMI down on all user data ports when LMI on the
network interface goes down, disabling all ports and deasserting their control leads.
Allows LMI to come back up and reenables the ports when LMI comes up on the network.
That is, LMI on each port follows the network interface’s LMI. The state of LMI on the port
will not affect the state of LMI on the network interface.
Port-1_Codependent_with_Net1-FR1 – Brings LMI down on the network interface when
LMI on Port-1 goes down (or LMI down on Port-1 when LMI on the network interface goes
down), and allows LMI to come back up when LMI comes back on the other interface.
That is, the LMI state for one interface is dependent on the other. Use this setting when
backup is through the router instead of the unit. It is not recommended since it makes fault
isolation more difficult.
Port-2_Codependent_with_Net1-FR1 – Reacts like the
Port-1_Codependent_with_Net1-FR1 selection, but for Port-2 instead. The state of LMI
on the network interface will not affect the state of LMI on Port-1.
Rtr-S0_Codependent_with_Net1-FR1 – Brings LMI down on the network interface when
LMI on Rtr-S0 goes down (or LMI down on Rtr-S0 when LMI on the network interface
goes down), and allows LMI to come back up when LMI comes back on the other
interface. That is, the LMI state for one interface is dependent on the other.

Port-1_Follows_Net1-FR1, Port-1_Codependent_with_Net1-FR1
Default Setting: Port-1_Codependent_with_Net1-FR1
For units that support ATM, configures the state of LMI on Port-1 and the state of the ATM
link on the network interface to be passed from one interface to another.
Independent – Handles the state of each interface separately so that the LMI state of
Port-1 has no effect on the state of the ATM link on the network interface, and vice versa.
Net1-FR1_Follows_Port-1 – Brings down VCs cross-connected to Port-1 on the network
interface when LMI on Port-1 goes down, and sends F5 OAM cells on all network VCs
cross-connected to Port-1 DLCIs to alert the network and far-end device that frame relay
data can not be delivered through the device. When LMI on Port-1 comes back up, the
network VCs are also re-enabled. This setting is useful at a central site when the remote
site router on the other end of the PVC connection can initiate recovery via a redundant
central site when there is a catastrophic central site LAN or router failure. Not
recommended for NSPs.
Port-1_Follows_Net1-FR1 – Brings down LMI on Port-1 when there is a physical failure
or ATM failure on the network interface. When the alarm on the network interface is
cleared, Port-1 is re-enabled and its control leads are reasserted. This setting is useful if
the router connected to Port-1 is used to initiate recovery when network failures are
detected.
Port-1_Codependent_with_Net1-FR1 – The LMI state for Port 1 and the Net1-FR1
interface are dependent on each other. If the LMI is down on either interface, the system
will bring the LMI down on the other interface. When the LMI is up on either interface, the
system will bring the LMI up on the other interface. When Port-1 LMI goes down, in
addition to bringing down the internal network frame relay link, the unit also sends
F5 OAM cells on all network VCs cross-connected to Port-1 DLCIs to alert the network
and far-end device that frame relay data can not be delivered through the device. Use this
setting when backup is through the router instead of the unit. Note that when the router is
disconnected, the NSP cannot access the unit using multiplexed VCs.

PPP
Possible Settings: Independent, Port-1_Follows_Net
Default Setting: Independent
Allows you to pass the state of PPP from one interface to the other.
Independent – The state of PPP on one interface does not affect the state of the other.
Port-1_Follows_Net – The state of PPP on Port 1 depends on the state of PPP on the
Network 1 interface. If PPP is down on Network 1, the system brings down PPP on the
Port 1 interface and disables the port, causing the DSR, CD, and CSR control leads to be
deasserted. If PPP is up on Network 1, the system enables Port 1 and asserts the control
leads.

provided by the network. In a LADS, or LDM, application (local area data set/limited
distance modem), where local and remote FrameSaver units are directly connected, one
of the units provides timing for both units.
Internal – Timing for the unit and its attached LADS partner is derived from the unit’s
internal clock. Use this setting when the unit will be used as a LADS primary timing unit,
where the FrameSaver unit establishes overall timing for the two interconnected units.
Receive – Timing for the unit is derived from the network Received signal. Use this setting
for standard DDS operation, or when the unit will be used as a LADS secondary timing
unit. See DDS Line Rate (Kbps).
DDS Line Rate
Possible Settings: Auto_On_No_Signal, Initialize_From_Network, 56, 64CC
Default Setting: Auto_On_No_Signal
Configures the network interface’s line speed to match the Digital Data Service’s (DDS’s)
line speed. This is the rate at which data is transmitted over the DDS line.
Display Conditions – This option only appears when Transmit Timing is set to Receive.
Auto_On_No_Signal – Automatically detects the line rate on the network interface
whenever a No Signal alarm is declared, the unit is reset, or the line rate is changed to
Auto_On_No_Signal and saved, then changes the unit’s operating rate to match the
network’s. It may take up to 15 seconds each time automatic rate detection and
adjustment occurs.
Initialize_From_Network – Automatically detects the line rate on the network interface
once, then changes the unit’s operating rate to match the network’s. Automatic rate
detection and adjustment, or Autobaud, will not occur again unless the line rate is
changed to Initialize_From_Network or Auto_On_No_Signal and saved. It may take up to
15 seconds for automatic rate detection and adjustment to occur.
56 – Forces the line rate to 56 Kbps.
64CC – Forces the line rate to 64 Kbps Clear Channel (72 Kbps on the line).

Network Initiated DCLB
Possible Settings: Disable, V.54_&_ANSI
Default Setting: V.54_&_ANSI
Allows the initiation and termination of the Data Channel Loopback (DCLB V.54 loop 2) to
be controlled by the receipt of a DCLB-actuate or DCLB-release sequence (either V.54 or
FT1-ANSI compliant) from the network or a far-end FrameSaver device. When enabled
and a DCLB-activate sequence is received, the unit initiates a DCLB on the network
interface. When a DCLB-release sequence is received, the DCLB is stopped.
Disable – DCLB-actuate and DCLB-release sequences are ignored.
V.54_&_ANSI – DCLB-actuate and DCLB-release sequences that comply with either V.54
or ANSI T1.403, Annex B standard will be recognized and will control initiation and
termination of a DCLB for this frame relay link. The actuate and release sequences do not
need to match (for example, a DCLB started with a V.54 actuate sequence can be
stopped with an FT1 release sequence).
DSU Latching Loopback
Possible Settings: Enable, Disable
Default Setting: Enable
Specifies whether the FrameSaver unit responds to the DSU Latching Loopback
sequence sent by the network, as specified by TR62310.

until the network receives the loopback release sequence.
Disable – Does not respond to the DSU loopback commands, or terminates the latching
loopback test if it is active.
NOTE: Because the latching loopback code is a control sequence, as opposed to a
bipolar violation sequence, user data may activate the loopback. Disable this option to
stop an unintentional latching loopback.
Require DSU Latching Loopback Preamble
Possible Settings: Enable, Disable
Default Setting: Disable
Specifies whether the FrameSaver unit requires the ANSI or FRF proposed preamble for
the network-initiated DSU Latching Loopback when detecting the loopback sequence.
Display Conditions – This option only applies when the unit is operating on a standard
DDS 64KCC circuit and DSU Latching Loopback (64KCC) is enabled.
Enable – Does not respond to the DSU Latching Loopback commands unless the
preamble is received.
Disable – Responds to DSU Latching Loopback commands, whether or not the preamble
is received.

Table 3-16. EIA-530-A/X.21/V.35 Data Port Physical Interface Options (2 of 3)
Transmit Clock Source
Possible Settings: Internal, External
Default Setting: Internal
Determines whether the DTE’s transmitted data is clocked into the FrameSaver unit by its
internal transmit clock or by the external clock provided by the DTE.
NOTE: Changing settings for this configuration option causes the FrameSaver unit to
abort any physical port tests, including any DTE-initiated loopback tests.
Internal – The FrameSaver unit uses the interchange circuit DB (ITU 114) – Transmit
Signal Element Timing (TXC) (DCE source) for timing the incoming data.
External – The DTE provides the clock for the transmitted data, and the FrameSaver unit
uses the interchange circuit DA (ITU 113) – Transmit Signal Element Timing (XTXC)
(DTE source) for timing the incoming data.
Invert Transmit Clock
Possible Settings: Auto, Enable, Disable
Default Setting: Auto
Determines whether the clock supplied by the FrameSaver unit on interchange circuit DB
(ITU 114) – Transmit Signal Element Timing (DCE Source) TXC is phase inverted with
respect to the clock used to time the incoming Transmitted Data (TD).
Auto – The port will check the clock supplied by the DCE on TXC on this port. If
necessary, the port will automatically phase invert the clock with respect to the transmitted
data.
Enable – Phase inverts the TXC clock. Use this setting when long cable lengths between
the FrameSaver unit and the DTE are causing data errors.
Disable – Does not phase invert the TXC clock.
Monitor DTR
Possible Settings: Enable, Disable
Default Setting: Enable
Specifies whether the state of the DTE Ready (DTR) circuit on the user data port will be
used to determine when valid data communication is possible with the DTE. When the
DTR off condition is detected, an alarm is generated, LMI is declared down, and no further
transfer of frame relay data can occur on this interface.
Enable – Interchange circuit CD (ITU 108/1/2) – DTR is monitored to determine when
valid data is sent from the DTE.
Disable – DTR is not monitored. DTR is assumed to be asserted and data is being
transmitted, regardless of the state of the lead.

Caller Identification Method
Possible Settings: Caller ID, Proprietary
Default Setting: Caller ID
Specifies the method used to identify callers.
NOTE: The Caller Identification Method setting must be the same at both ends of the
circuit.
Caller ID – Incoming calls will only be answered and the frame relay link on this Link
Profile will only be activated when the Caller ID received from the switch matches one of
the configured Inbound Calling IDs.
Proprietary – Incoming calls will always be answered, even when no Caller ID is provided
by the switch, provided the following conditions are met:
Link Status is set to Auto (the default).
At least one ISDN Link Profile is enabled.
When using the Proprietary method, the unit queries the originating unit for its Local
Phone Number. If the returned phone number matches one of the configured Inbound
Calling IDs, the call is accepted. If the queried unit does not respond with its phone
number within five seconds, the unit drops the call.
Alternate Outbound Phone Number
Possible Settings: 0 – 9, *, #, space, _, –, (, or )
Default Setting: none
Specifies an alternate phone number to call (the ISDN Called Party Identifier) when a call
using the primary Outbound Phone Number was unsuccessful. Up to 18 valid characters
can be entered. Each Outbound Phone Number must be unique. If not, the Alt
Outbound Phone Number is Not Uniquemessage appears and you must enter
another phone number.
NOTE: For every originating (alternate outbound) phone number entered, an
answering (inbound) phone number must be entered at the far end, and vice versa.
Currently active calls are not effected when this number is changed.
Assigning Time Slots/Cross Connections
The Time Slot Assignment/Cross Connect feature provides an easy method of
assigning time slots for frame relay data and creating cross-connections to the
synchronous data interface. The system allows you to assign DS0s on the T1
network interface and between the user data port and network interface in order to
share the T1 network.
You can also clear cross-connection assignments for the system, or for a selected
slot or interface.
NOTE:
Although it is not required, it is suggested that you progress through each
screen in order, from top to bottom.

Assigning Time Slots to the Network Interface
Before assigning network time slots for use by frame relay traffic, configure the
Network physical and Frame Relay options (if needed), then allow Time Slot
Discovery to autodetect and assign the appropriate time slots to frame relay.
If there are multiple Frame Relay data links on the network interface, or if Time
Slot Discovery is not currently active, you can manually assign time slots on the
network interface for frame relay traffic using the Frame Relay Network
Assignments screen. This screen is read-only when Time Slot Discovery is set to
Enable for the network interface.

Only those DSX-1-to-Network assignments from page 1 are displayed on this
page, from left to right and top to bottom in ascending order, by network and time
slot.
When a CGA condition (LOS, OOF, or AIS) is declared for a T1 interface, the
signaling bits being transmitted to the other T1 interface for the DS0 are forced to
idle for two seconds (except for user-defined patterns which are transmitted
immediately). This drops any call in progress. The signaling bits are then forced to
the selected state (Busy or Idle), and remain in this state until the CGA condition
clears. At this point, the received signaling bits from the T1 interface which
formerly had the CGA condition are passed through to the other T1 interface.
NOTE:
Trunk conditioning will only occur on DS0s that are cross-connected to
another T1 interface. All other DS0s remain unaffected by trunk conditioning.
Values, in each of the fields on both the Network side and the DSX-1 side.
Although you can choose any value for the DSX-1 side, the default value
displayed is based on a typical setting that would be used with the corresponding
Network side value. Typical pairs of values are shown in the table below. If you
change the Network side value, the DSX side value is changed to the
corresponding default value.

None
No signaling used on this DS0. Use this setting if
None
there is no voice signaling information being passed
on this DS0 (clear channel).
RBS (default)
Robbed Bit Signaling is used on this DS0, but no
trunk conditioning. Signaling bits will be passed to the
T1 interface to which this DS0 is cross-connected
when this T1 interface is not in CGA, but the signaling
bits will be all ones when CGA is present.
RBS
The following values configure the cross-connect for RBS, as well as perform the

Initialize_From_Net1FR1 – The LMI type supported on this frame relay link will be
configured to match the LMI protocol initially discovered on the primary Network frame
relay link (Net1FR1). LMI Protocol is set to None internally, but once a protocol has
become active or is set on the primary Network link, the protocol will be set to the same
value on this link (Standard, Annex-A or Annex-D). The protocol will not be updated based
on changes to Net1FR1 after being set initially.
Display Conditions – This option value only appears for a user data port.
Initialize_From_Interface – The LMI type supported on this frame relay link will be
configured to match the LMI protocol discovered from the attached Network line or DTE
device. Once a protocol has become active, the protocol will be set to the protocol
discovered (Standard, Annex-A or Annex-D) on the frame relay link. The protocol will not
be updated after being initially discovered. Frame relay links on user data ports discover
the LMI protocol from an attached device via LMI status polls. Frame relay links on the
network interface discover LMI protocol by sending polls to an attached Network line and
“listening” for correct poll response messages.
Auto_On_LMI_Fail – The LMI type supported on this frame relay link will be configured to
match the LMI protocol discovered from the attached Network line or the DTE device
whenever an LMI Link Down failure occurs. This option is available for frame relay links on
the Port and network interfaces. Frame relay links on user data ports discover the LMI
protocol from LMI status polls by attached DTE devices. Frame relay links on the network
interface discover LMI protocol by sending polls to an attached Network line and
“listening” for correct poll response messages.
Standard – Supports Standard LMI and the Stratacom enhancements to the Standard
LMI.

Node Subnet Mask
Possible Settings: 000.000.000.000 – 255.255.255.255, Clear
Default Setting: 000.000.000.000
Specifies the subnet mask needed to access the node. Since the subnet mask is not
bound to a particular port, it can be used for remote access via a management PVC.
000.000.000.000 – 255.255.255.255 – Shows the subnet mask for the node, which can be
viewed or edited.
Clear – Fills the node subnet mask with zeros. When the node’s subnet mask is all zeros,
the IP protocol creates a default subnet mask based upon the class of the IP address:
Class A: 255.000.000.000, Class B: 255.255.000.000, or Class C: 255.255.255.000.
Default IP Destination
Possible Settings: None, Modem, COM, Ethernet, PVCname
Default Setting: None
Specifies an IP destination to route data that does not have a specifically defined route.
Examples:
If the default IP network is connected to the communications port, select COM.
If the default IP network is connected to a far-end device over the management PVC
named London for the remote device located in the London office, select the PVC
name London (as defined by the Name configuration option, Table 3-32, Management
PVC Options).
NOTE: If the link to the IP destination selected as the default route becomes disabled
or down, the unrouteable data will be discarded. Make sure that the link selected is
operational, and if that link goes down, change the default destination.
CAUTION: Use care when configuring a default route to an interface that has a subnet
route configured at a remote end where the NMS, router, LAN adapter, terminal server,
etc. is connected. Communicating with an unknown IP address on the subnet will
cause temporary routing loops, which will last 16 iterations times the retry count.
None – No default network destination is specified. Unrouteable data will be discarded.
This is the recommended setting.
Modem – Specifies that the default destination is connected to the modem port. Only
appears when the modem port Use option is set to Net Link.
COM – Specifies that the default destination is connected to the COM port. Only appears
Ethernet – For the FrameSaver SLV 9126 or 9128, specifies that the default destination is
connected to the Ethernet port. Only appears when the Ethernet port’s Interface Status
option is enabled. When selected, the Default Gateway Address must also be configured
PVCname – Specifies a name for the management PVC. Only appears when a
management PVC name is defined for the node. For example, when the network is
connected to a remote device located in the London office, London can be specified as
the PVC name, which is the link between the local FrameSaver unit and the one located in
London. London would appear as one of the available selections.

Table 3-40. Auto Backup Criteria Options (1 of 2)
Auto Backup
Possible Settings: Enable, Disable
Default Setting: Disable
Determines whether backup for the access unit is automatically performed when the
primary physical link or LMI, or a DLCI on a PVC connection fails, or when latency is
exceeded.
When enabled, the access unit automatically enables the Alternate Link configuration
option, and establishes an alternate DLCI and EDLCI, rerouting traffic over the backup
interface. (See Table 3-32, Management PVC Options, to configure the alternate DLCI
and alternate EDLCI.)
NOTE: Auto Backup cannot be enabled unless LMI Behavior is set to Independent
Enable – Reroutes traffic over the backup (alternate) interface.
Disable – Does not reroute traffic over the backup interface.
DLCI Down Backup Activation Delay (sec)
Possible Settings: 0 – 3600
Default Setting: 0
Specifies the number of seconds the unit will wait once a DLCI is declared down before it
initiates backup. A DLCI is declared down when the DLCI changes to Inactive status in an
LMI response, or when there is an LMI or physical link failure. When a delay is configured,
the unit is more tolerant of network glitches, or repeated short outages, before going into
backup, minimizing bouncing between network and backup services.
0 – 3600 – Specifies the amount of time for the delay.
DLCI Down Backup Activation Transition Threshold
Possible Settings: 1 – 10
Default Setting: 1
Specifies how many times a primary destination DLCI transitions up or down during the
DLCI Down Backup Activation Delay period before the unit initiates backup, provided the
DLCI is active when the delay period ends.
1 – 10 – Specifies the number of transitions allowed between Active and Inactive status.
Backup Restoration Delay (sec)
Possible Settings: 0 – 3600
Default Setting: 0
Specifies the number of seconds the unit will wait after all backup alarm conditions have
cleared for a primary destination DLCI before the backup connection is terminated.
0 – 3600 – Specifies the amount of time for the delay.

Setting Up Automatic Backup Configuration
The Automatic Backup Configuration feature is used to automatically create
alternate DLCI records and PVC connections on the ISDN DBM (backup) interface
for current or newly discovered PVC Connections and Management PVCs.
This feature is already set up, with Single_Site_Backup as the default for units with
a BRI DBM and Multi_Site_Backup for units with a PRI DBM. If the unit at the
central site has a BRI DBM, change the Automatic Backup Configuration to
Multi_Site_Backup, if necessary.

Single_Site_Backup
Alternate destinations are automatically configured using a
single ISDN Link Profile to backup all network PVC
Connections and Management PVCs over the primary
destination ISDN link.
(default for a BRI DBM)
(Used at remote sites since
only one ISDN link to the
central-site is needed.)
Initially, PVCs with alternate destinations are configured on
the first ISDN Link Profile using the same DLCI number as
the network DLCI being backed up. However, primary
destination PVCs on the ISDN DBM interface are
automatically updated to use a different DLCI number for
the alternate destination DLCI, derived from the first SLV
message received on the each network DLCI.
Multi_Site_Backup
Alternate destinations are automatically configured using a
separate ISDN Link Profile to backup each network PVC
Connection and Management PVC over the ISDN interface.
(default for a PRI DBM)
(Used at central sites since
multiple ISDN links are
needed, one for each
remote-site.)
Initially, all DLCIs are configured on the ISDN links using
the same DLCI number as the network DLCI being backed
up. However, primary destination PVCs on the ISDN DBM
interface are automatically updated to use a different DLCI
number for the alternate destination DLCI, derived from the
first SLV message received on the each network DLCI.
Automatically created alternate destination Link Profiles
appear as Bkupnnnn, nnnn being the DLCI number (e.g.,
Bkup200 would be configured for network DLCI 200).

Restricting Automatic Backup and Configuring Backup Timers
You can specify when auto backup is allowed to occur. If backup is restricted and a
backup is active when the allowed time for backups is over, then the backup is
terminated and the data is returned to the primary data path regardless of the
primary path’s condition.
You can restrict auto backup to occur only:
n
n
On certain days of the week
At certain times of the day
The following additional features can be configured:
n
Delays can be configured to control how long the unit will wait before initiating
backup when a DLCI is declared down, and how long it will wait to restore
service once the DLCI is declared operational again.
n
A threshold can be set to determine how many times a primary destination
DLCI can transition between Active and Inactive before the unit initiates
backup.
Procedure
To set the criteria and backup timers for automatic backup:
1. Enable Auto Backup.
Main Menu→Configuration→Auto-Backup Criteria
When a failure occurs, the unit automatically enables the Alternate Link and
traffic is rerouted over the backup (alternate) interface.
2. Specify the amount of delay after a DLCI is declared down before backup is
initiated (DLCI Down Backup Activation Delay).
3. Set the threshold for transitions of the DLCI’s status before backup is initiated
(DLCI Down Backup Activation Transmission Threshold).
4. Specify the amount of delay after a DLCI is declared operation before backup
is ended (Backup Restoration Delay).
5. Specify When Auto Backup Allowed – Always or Restrict. If Restrict is
selected, specify the days and hours of the week during which automatic
backup can take place.

PVC Backup Over the Network Interface
Generally, backup can be performed on the network interface’s frame relay link
using a backup PVC, as well on an ISDN link; the unit does not have to have the
ISDN DBM feature.
In this case, create a DLCI Record on the network interface that will be used for
backup, then modify the PVC Connections or Management PVCs to add the
alternate destination.
Setting Up Back-to-Back Operation
Using this special feature, you can set up two FrameSaver units that are
connected back-to-back without frame relay switches between them, as in a test
bench setup using a crossover cable.
Changing Operating Mode
When setting up back-to-back operation:
n
One unit must be configured for Standard operation, which is the setting for
normal operation.
n
The other unit must be configured for Back-to-Back operation so it presents
the network side of the UNI (user-network interface).
Only one of the units will have its operating mode changed.
Procedure
To set up back-to-back operation:
1. On the unit to be configured for Back-to-Back operation, manually configure
DLCIs; DLCIs should be configured before connecting the two units.
2. Access the Change Operating Mode screen.
Main Menu→Control→Change Operating Mode
3. Select Back-to-Back Operation, and respond Yes to the Are you sure?
prompt.
4. Save the change.
Procedure
To return the unit to normal operation:
1. Return to the Change Operating Mode screen and switch back to Standard
Operation.
2. Respond Yes to the prompt and save the change. The units can be
reconnected to a standard frame relay network.
