About the Frame Relay Access Unit

 1-2

9121-A2-GB20-00

June 1997

Configuration Shortcuts

Configuration shortcuts have been provided to simplify configuration of the
access unit and its features. Initially, this feature can be used to speed setup of
the access unit. Then, by selecting a frame relay discovery method, configuration
and cross-connection of DLCIs (and EDLCIs) can be performed within the access
unit on an automatic and continuing basis.

Configuration shortcuts provided by the access unit include:

Configuration templates – Configures the non-frame relay portion of the
access unit.

Based upon the template selected that best fits your application, one or two
ports can be automatically configured.

Frame relay discovery method – Configures the frame relay portion of the
access unit.

Based upon the local management interface (LMI) status response
messages, the access unit automatically “discovers” a network DLCI and
cross-connects the DLCI to a port DLCI provided the port is configured as the
user side. Management PVCs can also be “discovered” and cross-connected.

Backup ISDN BRI DBM

Available as an optional feature, the ISDN BRI DBM provides fast, easy, and
flexible backup to limit data loss when the physical circuit fails. With the DBM
installed, the best and fastest backup decisions are made automatically.

Backup capabilities provided when an ISDN BRI DBM is installed include:

Automatic backup when the circuit fails.

Automatic restoration when the circuit recovers.

Alternate backup destinations or paths.

Manual call control.
