Configuration: Call Backup
This section provides instructions for configuring the HSIM or CyberSWITCH to automatically
backup a PPP dedicated/permanent connection or a Frame Relay PVC using a dial-up ISDN.
These are the two primary uses. All connections configured as call backup are continuously
monitored for a failed condition. Whenever a primary connection with call backup fails, the
backup call is automatically made using Dial-on-Demand (DoD). Once the failed connection is
restored the backup call may be automatically closed. DoD automatically brings up the backup
SVC connection whenever the primary connection has failed and there is traffic to be forwarded
across the backup SVC.

This example assumes the setup shown in
, using two CSX400s with primary
connections using WPIM-T1s (WPIM-E1, WPIM-DDS, or WPIM-SY could also be used) and
with HSIM or CyberSWITCH backup modules installed in each CSX400. The NT-1 is needed if
the connection to the Telco cloud has a U interface.
