— Leased Line mode for standard DSU installation and operation
— Device health and status
— Layer 1 (Physical) and Layer 2 (Frame Relay) performance statistics
— Basic physical testing and non-disruptive PVC diagnostics
— A troubleshooting DLCI (Data Link Connection Identifier) for service
referred to as Feature Set or Group 2) provide all the basic FLEX capability,
plus advanced SLV features. When additional SLV data is collected and the
unit is accessed from an OpenLane SLM system, Web access to the following
information is available:
— TruePut™ Technology using Frame and Data Delivery Ratios
— Web browser access to all diagnostic and reporting functions
— Historical SLA (Service Level Agreement) verification and trend reports
— Real-time RMON (remote monitoring) alarms and configurable alarm

on page 1-7 for other features and more
If the unit does not have the additional SLV features, full FLEX SLV capability can
be activated at any time by ordering an Activation Certificate. The OpenLane SLM
system, Release 5.3 or later, is required to schedule activation of FLEX SLV
features in units, and to manage activations.
August 20019123-A2-GB20-20

Page 17
1. About the FrameSaver FLEX 9123
To obtain an Activation Certificate, provide the model to be upgraded (i.e., 9123),
your OpenLane system license key number, and the number of FrameSaver units
to be upgraded to FLEX SLV capability (the number of activations to be included
on the certificate). You can order the certificate for a single unit or for many units.
Your Activation Certificate will include an Activation Certificate Number, the
Feature Group Number for the additional SLV features (Feature Group 2), your
OpenLane license key number, and the number of device activations ordered.
When the 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 certificate.
The following table summarizes the features that are included in the two feature
sets. See

OpenLane SLM System
Being standards-based, the OpenLane SLM (Service Level Management) system
can be used with other management applications like HP OpenView or IBM’s
NetView. OpenLane includes HP OpenView adapters for integrating OpenLane
features with the OpenView Web interface.
Being Web-based, the OpenLane system provides Web access to the data
contained in the database to provide anytime, anywhere access to this information
via a Web browser.
Some of the OpenLane system’s features include:
Real-time performance graphs provide exact performance measurement
details (not averages, which can skew performance results) of service level
agreement (SLA) parameters.
Historical SLV graphs provide service level management historical reports so
frame relay SLAs can be verified.
Diagnostic troubleshooting provides an easy-to-use tool for performing tests,
which include end-to-end, PVC loopback, connectivity, and physical interface
tests.
Basic configuration allows you to configure FrameSaver devices, and set
RMON alarms and thresholds. Network DLCI Circuit IDs can also be
assigned.
Automatic SL V device and PVC discovery allows all SL V de vices with their SLV
Delivery Ratio configuration option enabled to be discovered automatically,
along with their PVCs.
A FrameSaver unit can be reset from the OpenLane system.
Firmware downloading provides an easy-to-use tool for downloading to an
entire network or a portion of the network.
On-demand polling of FrameSav er devices, and SNMP polling and reporting
are available.
Multiple maintenance schedules allow for the scheduling of more than one
periodic maintenance period, and provides a report for each scheduled task.
Multiple Circuit IDs allow multiple access levels so network service providers
can offer their customers service level-specific access to network
management information, and so end users can have open access to network
management information without losing control of their network(s).

3. 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, 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; it cannot be
configured automatically.
The following will occur when a Frame Relay Discovery Mode is selected:

The default discovery mode is 1MPort (management DLCIs multiplexed with data

same number as the network interface DLCI), and a Management PVC, then

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.

LMI on Po rt-1 goes down (or LM I do wn on Port-1 when LMI on the network interf ac e goes

That is, the LMI state for one interface is dependent on the other. Use this setting when

Service Type set to Leased Line
interface time slots.
You can also clear cross-connection assignments for the unit, or for a selected

Limiting Access
The FrameSaver unit provides access security on the following interfaces:
Asynchronous (async) terminal
Telnet
FTP
SNMP
Up to two direct or T elnet sessions can be active at any given time; that is, you can
have two simultaneous Telnet sessions, or one Telnet session and one active
asynchronous terminal session, or two simultaneous asynchronous terminal
sessions.
Controlling Asynchronous Terminal Access
Direct asynchronous terminal access to the menu-driven user interface can be
limited by:
Requiring a login.
Assigning an access level to the port or interface.
