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:

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
and port DLCIs.
1PPort
Auto-Configuration is enabled on Port-1.
A Port-1 DLCI is created for each network DLCI and
automatically cross-connected to it.
Payload management is configured for the network
DLCI and assigned the Node IP Address.

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.

Default Setting: Independent
Configures the device to allow the state of the LMI to be passed from one interface to
another, determining how the unit will handle a change in the LMI state. Sometimes
referred to as LMI pass-through.
Display Conditions – Port-n options are available on CSU/DSUs and Rtr-S0 options
are available on FrameSaver SLV Routers. Port-2 options are available on units with
two data ports.
NOTE: LMI Behavior cannot be changed while Auto Backup is enabled. A warning

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.

Table 3-9. DDS Network Physical Interface Options (1 of 2)
Transmit Timing
Possible Settings: Internal, Receive
Default Setting: Receive
Specifies the unit’s timing source based upon how the unit will be used. When the unit is
connected to a DDS (Digital Data Service) network for standard operation, timing is
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).

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.
Enable – Responds to DSU latching loopback commands. The unit remains in loopback
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.

Valid Network time slots are either Available or contain a DSX-1 time slot
assignment.
Valid DSX-1 time slots are those that are unassigned, including the currently
assigned time slot.
Order of display is as follows:
— Available is the first selection.
— Then, from the lowest DSX-1 interface to the highest DSX-1 interface.
— Then the lowest available time slot number to the highest available time
slot number.
For example, if the cursor is on a field with the Available value under
assigned time slot Ntt, pressing the Spacebar causes this field’s values to
cycle through all valid DSX-1 time slots, starting with Ds-p/yy, assuming it is
unassigned. If Ds-p/tt is already assigned, the next valid time slot in the order
described above is displayed.

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
trunk conditioning. Although ABCD signaling bits for each setting are described,
only AB bits are transmitted when the cross-connected T1 network interface is
using D4 framing.

Default Setting:
For a user data port link: Initialize_From_Interface
For a network link: Auto_On_LMI_Fail
Specifies either the LMI protocol supported on the frame relay interface or the discovery
source for the LMI protocol.
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.
Annex-A – Supports LMI as specified by Q.933, Annex A.
Annex-D – Supports LMI as specified by ANSI T1.617, Annex D.

DLCI Priority
Possible Settings: Low, Medium, High
Default Setting: High
Specifies the relative priority for data received on the DLCI from an attached device (also
known as quality of service). All data on Port 1 is cut-through, as long as there is no
higher-priority data queued from another user port. The DLCI priority set for an interface
applies to data coming into that interface. For example, the priority set for DLCIs on Port 1
applies to data coming into Port 1 from the attached equipment (such as a router).
NOTE: For units with multiple user data ports, since pipelining occurs on Port-1, it is
recommended that higher priority data be connected to Port-1 .
Display Conditions – This option is not available for the network interface or, if the
model has ISDN backup capability, an ISDN DBM interface.
Low – Data configured for the DLCI has low priority.
Medium – Data configured for the DLCI has medium priority.
High – Data configured for the DLCI has high priority.
Outbound Management Priority
Possible Settings: Low, Medium, High
Default Setting: Medium

Setting Up to Use the Modem PassThru Feature
Dial-in access to the router is possible via the Modem PassThru feature, also
known as the Router Assist feature. The FrameSaver unit’s COM port must be
connected to the router’s auxiliary (AUX) or console port, and the COM port must
be configured for this use.
When this feature is set up and active, a logical connection between the unit’s
modem and COM ports is made, and data received over the modem port is
transmitted out the COM port to the router’s AUX or console port. When an escape
sequence (minus, minus, minus, with a minimum of 50 ms between each) is
detected, the FrameSaver unit switches back to normal user interface operation.
Procedure
1. Configure the COM port to use Modem PassThru.
Main Menu→Configuration→Management and Communication→
Communication Port
2. Set Port Use to Modem PassThru.
3. Save the configuration.

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.
Main Menu→Auto-Configuration→Automatic Backup Configuration
If you select . . .
Then . . .
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).
Disabled
No automatic configuration takes place on the DBM
interface and no alternate destinations are created for
PVCs.

Modifying ISDN Link Profiles
Once an ISDN Link Profile is configured using the Automatic Backup Configuration
feature, phone numbers and Calling IDs need to be entered. FrameSaver units
with ISDN backup capability can originate or answer calls, as needed, so both
phone numbers and Calling IDs are needed.
Procedure
1. Select Link Profiles, then Modify.
Main Menu→Configuration→ISDN→Link Profiles
2. Add a name and phone number to the ISDN Link Profile(s) created by
Automatic Backup Configuration.
— Name for the destination entered (e.g., Tampa). The default setting is
HQ_Site for the first ISDN Link Profile.
— Phone numbers entered:
For Originating a Backup Call
For Answering a Backup Call
Outbound and Alternate Outbound
phone numbers
Inbound Calling ID1 and ID2
These are the phone numbers of units
from which calls will be accepted.
Valid characters can include:
Numbers (0–9)
Valid characters can include:
Numbers (0–9)
Special characters * and #
Spaces
Parentheses ( )
NOTES:
Remember to include local dial-out numbers (i.e., 9, then the number).
For every originating (outbound) phone number entered, an answering
(inbound) phone number must be entered at the far end, and vice versa.
— Maximum Link Rate (Kbps) set to the appropriate speed, if necessary.
— Caller Identification Method set to Proprietary if call validation is not
required. The setting must be the same at both ends of the circuit.
— An Alternate Outbound Phone Number should a call using the primary
Outbound Phone Number be unsuccessful, if desired.

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.
6. Save the configuration.

Link Trap Interfaces
DLCI Traps on Interfaces
ISDN Dial Control Traps
When DBM is selected, trap messages are generated for linkUp and linkDown
events on DLCIs and frame relay links for the originating DBM interface only. For
peer-to-peer backup, backing up to a neighboring node like a regional node, dial
control traps can be sent to trap manager(s).
Configuration Options, for configuration information.
Assigning DLCIs to a Backup Group
DLCIs can be assigned to a Backup Group to reduce backup charges when
redundant PVCs have been configured. This feature prevents backup as long as
any DLCI in the group is operational.

Backup is not initiated as long as one DLCI in the group is operational.
Backup is terminated as soon as one DLCI in the group becomes operational.

4. Feature-Specific Configuration
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.
