1. About the FrameSaver SLV

FrameSaver Diagnostic and SLM Feature Sets

Depending upon the model ordered, the FrameSaver unit has the basic
FrameSav er frame relay and diagnostic capability, or it is enhanced with additional
SLM (Service Level Management) reporting capabili ty. These are referred to as
feature sets, which pro vide different le vels of intelligence f or monitoring, managing,
and reporting performance of the unit.

The two feature sets include:

additional SLM capability.

If the unit does not have the SLM feature set, full SLM capability can be activated
at any time by ordering a Feature Activation Certificate. The OpenLane SLM
system Release 5.3 or above is required to schedule activation of advanced SLM
features in units, and to manage activations.

To obt ain a Feature Activation Certificate, provide the model to be upgraded, your
OpenLane system license key number , and the number of FrameSaver units to be
upgraded to SLM capability. You can order the certificate for a single unit or for
many units. Your Feature Activation Certificate will include an Activation Certificate
Number, the Feature Group Number for the additional SLM features, your
OpenLane license key number, and the number of device activations ordered.

When the Feature Activation Certificate arrives, add the Activation Certificate
Number to your OpenLane SLM application’s database . Activations can occur at
any time, for as many units as desired, until no activations remain for the
certificate. When ready to activate units, simply select the units to be activated and
schedule the activations. The activations occur when scheduled, and OpenLane
updates the certificate information. The OpenLane system also provides a
Certificate Summary Report to assist you in the management of the cert ificate.

circuit. This feature also makes it possible to run nondisruptive PVC tests.

Extensive Testing Capability.



Provides a variety of tests to identify and
diagnose device and network problems, including nondisruptive PVC
loopbacks and end-to-end connectivity. Tests can be commanded from the
unit’s menu-driven user interface or the OpenLane system.

These tests include V.54 or FT1-ANSI data channel loopback support so the
frame relay network service provider can perform a physical loopback from its
own switch without having to contact the local service provider for loopback
activation.

LMI Packet Capture.

1. About the FrameSaver SLV

Modem PassThru.



Provides access to another device’s VT100-compatible
user interface over a dial connection. When this feature is enabled, a logical
connection between the unit’s modem and COM ports is created, allowing
access to a collocated device’s serial port via the FrameSaver unit’s internal
modem. This feature is sometimes referred to as the Router Assist feature.

Optional ISDN Backup.



When an ISDN BRI or PRI DBM (Basic Rate
Interface or Primary Rate Interface Dial Backup Module) is installed, the
following ISDN backup features are provided:

— Provides automatic dial backup through the ISDN for data when primary

frame relay network or access line failures occur, then automatically
restores data to the primary route when service returns to normal. Backup
is supported regardless of whether or not Caller ID is provisioned on the
ISDN circuit. A secondary backup phone number is also available to call
when a backup link cannot be established with the primary backup site.

— Supports simultaneo us origin ation, answering, or origination and

answering backup calls, as needed, based upon how the ISDN Link
Profile is set up. This feature is also known as peer-to-peer calling.

— Provides automatic configuration of an alternate route and DLCI for

automatically created PVCs at either the remote site or central site based
upon the learned far-end DLCI number. When the automatic backup
feature is enabled, backup and restoration occur automatically.

— Provides backup timers that can be configured to better control the

amount of time required before backup is initiated, when a backup call will
be terminated once the failure condition clears, and a delay before normal
service is restored. These features are useful during periods of frequent
service disrup tion.

In addition, round trip latency thresholds can be configured that will initiate
backup when configured thresholds are exceeded.

— Supports backup call groups, where redundant PVCs can be assigned to

a specified call group. Using this feature, the unit only goes into backup
when
soon as

PVCs in the group are down, and it returns to norm al service as

all

PVC in the group is operational again. This feature is useful

one

when multiple PVCs are going to redundant central sites.

— When the SLV Sample Interval is set to 10 seconds, provides advance

detection of network problems before a DLCI Down indication is received,
to minimize data loss.

— Provides customer premises equipment (CPE) with a Backward Explicit

Congestion Notification (BECN) when backup bandwidth is not sufficient
for the traffic, allowing the CPE time to slow traffic to the ISDN before the
network starts discarding data.

— Supports Frame Relay Forum Multilink Frame Relay Implementation

Agreement – FRF. 15 so backup bandwidth can be increased by
aggregating multiple B-channels over the ISDN link.

— Supports collection of call and call attempt statistical information that can

be viewed from the menu-driven user interface or via SNMP, and supports
alarm generation and call security, as well.

1. About the FrameSaver SLV

— Provides test call capability on ISDN backup links so ISDN and DBM

function can be verified before there is an actual primar y link failure and
switched over to the backup link. Periodic tests are recommended, which
can be performed from the menu-driven user interface, or through SNMP
commands. Multiple Last Cause Values are also provided to assist in
troubleshooting ISDN problems.

FrameSav er SLV 9126 units can be equipped with a BRI DBM, which supports
up to two B-channels, which may have a different destination. The DBM is
factory installed in the 9126-A2, and may be field-installed in the 9126-A1.

FrameSav er SLV 9128 and 9128-II 1-slot units can be equipped with a PRI
DBM, which supports up to 23 B-channels, or a BRI DBM. Carrier-mounted
FrameSav er SLV 9128 and 9128-II NAMs support a PRI DBM only.

Configurable FTP Transfer Rate.



Allows you to control the transmit rate
when downloading firmware into the FrameSaver unit and uploading user
history statistics to an NMS (Network Management System) via the COM port
connection or a management PVC so the data can be transferred as a
background task using the standard File Transfer Protocol (FTP) over
extended periods of time using low bandwidth.

RMON User History Performance Statistics via SNMP Polling.



Provides
access to the physical interface and basic frame relay performance statistics
by polling the FrameSaver unit using SNMP (Simple Network Management
Protocol). These statistics are available real-time via the Enterpri se MIB and
historically as an RMON2 User History object.

Frame Relay Traffic P o li cing.



Ensures proper alignment and correlation of
CIR (Committed Information Rate) values between the FrameSaver unit and
the network switch. When this feature is enabled, the unit can enforce CIR and
EIR (Excess Information Rate), marking frames that exceed CIR as DE
(Discard Eligible) using the same method used by the switch.

Service P rovider S upport.



Provides information and tools useful to network

service providers, which includes the following:
— IP Routing Table – Shows the IP routing table for the FrameSaver unit,

with network as well as host routes, the number of hops to the destination,
the method by which the route was added to the table, the interface used
to get to the destination, and how long the route has been in existence.

— Trap Event Log – Displays the SNMP (Simple Network Management

Protocol) trap event log for the F rameSav er unit fr om the menu-driven user
interface, with the most recent events first, keeping a running total for all
trap events stored, the amount of time since the event was logged, plus a
description of the trap.

— Troubleshooting PVC – Provides a dedicated troubleshooting

management link that helps service providers isolate problems within their
network.

ATM VPI/VCI and DLCI Correlation.



For networks with both ATM and frame
relay-access endpoints, allows the FrameSaver unit to report the or iginating
Virtual Path and Channel Identifier (VPI/VCI) in the far-end ATM-access
endpoint where the local DLCI is mapped so they can be correlated for
OpenLane SLV reports.

Setting Up the Modem

The unit has an internal modem for dial-in access to the menu-driven user
interface, as well as dial-out capability when an SNMP trap is generated. When the
modem will be used to dial out, Modem Directory phone numbers need to be set
up. Otherwise, simply configure or change dial-in access to the unit.

The modem port is already configured for connection to an asynchronous terminal
and dial-in access, with Port Use set to Terminal. However, additional changes
may be needed (see Table 3-25, Modem P ort Options).

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 FrameSav er unit’s COM port must be
connected to the router’s auxiliar y (AUX) or co ns o le p ort, and the C O M p ort must
be configured for this use.

When this feature is set up and active, a logical connection between the unit’s
modem and COM por ts is made, and data received over the modem port is
transmitted out the COM port to the router’s A UX 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.

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, 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
FrameSav er unit’s user data port) must be configured manually.

Port-1 data and the other for management), a standard P ort-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,

network side are IP Enabled (not standard or multiplexed) DLCIs. In addition,
payload management is configured for the network DLCI and assigned the Node

Configuration options set by selecting a discovery mode can be manually
modified, refined, or deleted at any time using the Configuration menus. No

Restricting Automatic Backup and Configuring Backup Time r s

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:

On certain days of the week



At certain times of the day



The following additional features can be configured:

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.

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 criteri a 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.

Main Menu→Configuration→Management and Communications
SNMP Traps

The configuration options for doing this include:

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).

See Table 3-22, SNMP Traps and Trap Dial-Out 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.

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:

One unit must be configured for Standard operation, which is the setting for



normal operation.
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
prompt.

Default Setti ng: 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.

NOTE: LMI Behavior cannot be changed while Auto Backup is enabled. A warning
message appears at the bottom of the screen if auto backup is enabled. First, disable
Auto Backup, and then change LM I Behavior.

Independent – Handl es the LMI state of each interf ac e sepa rately so that the LMI st ate of
one interf ace has no effect on the LMI state of another interf ace. Provides LMI Spoof ing.
This is the recommended set ti ng when backup is confi gured, and for Network Service
Providers (NSPs).

Net1-FR1_Follows_Port-1 – Brings LMI down on the network interface when LMI on
Port-1 goes down, disab lin g the network in terf ace and deass erting its cont rol 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 conne ction can initiate recovery via a redundant
central site when there is a catastrophic central site LAN or router failure. Not
recommended for NSPs .

network interf ac e comes ba ck up, P ort-1 is reena bled and i ts cont rol l eads are r eass erted.
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 i s useful if the router
connected to Port-1 is used to initiate recovery when network failures are detected.

Port-2_Follows_Net1-FR1 – React s like the Port-1_F ollows_Net1-FR1 selection, but for
Port-2 instead.

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 t o come back up and reenabl es the ports when LMI comes up on the network.
That is, LMI on each port follows the network interface’s L MI. 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 whe n
LMI on P ort- 1 goes down ( or LMI down on Port-1 when LMI on the network interface goes
down), and allo ws LMI to come back up when LMI comes back on t he other interface.
That is, the LMI state for one interf ace is dependent on the other. Use this setting when
backup is thr ough the r outer i nstead of the unit . It is
isolation more dif fi cult.

Port-2_Codependent_with_Net1-FR1 – Reacts like the

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.

Enter one of the values shown in Table 3-12, Signaling and 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.

Initialize_From_Interface,
Auto_On_LMI_Fail,
Standard,
Annex-A,
Annex-D

Default Setti ng:

For a user data port link:
For a network link:

Specifies either the LMI protocol supported on the frame relay interface or the discovery
source for th e LMI protocol.

Initialize_From_Net1FR1 – The LMI type supported on this frame relay link will be
configured to match the LMI protocol initiall y dis covered on the primary Network fr am e
relay link (Net 1FR1). LMI Protocol is set to None inte rnally, but once a protocol has
become active or i s set on the primary Network link, the protocol will be set to the same
value on thi s link (St andard, Anne x-A or Anne x-D) . The pr otocol will
on changes to Net1FR1 after being set initially.

Display Conditions

Initialize_From_Interface – The LMI type supported on this frame relay link will be
configured to match the LMI protocol discovered from the attached Ne twork 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 r elay link. The protoc ol wi ll
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 sen ding polls to an attached Network li ne and
“listening” for correct poll response messages.

Auto_On_LMI_Fail – The LMI type supported on thi s fr ame r ela y lin k will be c onf igured to
match the LMI protocol discovered from the attached Network line or the DTE device
whenev er an LMI Link Do wn fai lure occurs. This option i s av ai labl e f or fra me rela y li nks on
the Port and network interfaces. Frame relay links on user data ports discover the LMI
protocol from LMI status polls by att ached DTE devices . Frame relay links on the network
interfa ce discover LMI prot ocol 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 b y Q.933, Annex A.
