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.

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
DLCIs on Port-1). In this mode, for each DLCI discovered on the network, the unit

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

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.
Based upon the setting of Service Type on the Easy Install screen, the following
cross-connection assignments can be made:
Service Type set to Frame Relay
time slots.
Service Type set to Leased Line
interface time slots.
You can also clear cross-connection assignments for the unit, or for a selected
interface.
NOTE:

Use the following procedures to assign cross connections.
Assigning Frame Relay 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 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

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.
