Sample ATM Backbone SwitchModule Configurations 1-13

The features of the dual-homing/module redundancy configuration include:

■Load balancing

LEC support is distributed manually across two ATM Backbone SwitchModules

■ATM PHY redundancy

On either ATM Backbone SwitchModule, if the loss of any critical function is detected, the redundant ATM OC-3 card becomes active and the primary ATM OC-3 card is disabled.

■Module redundancy

Using spanning tree parameters, one ATM Backbone SwitchModule assumes the LEC support of the other ATM Backbone SwitchModule if the other ATM Backbone SwitchModule fails.

Refer to the CoreBuilder 5000 SwitchModule User Guide for information on Spanning Tree parameters and configuration information.
