Figure 9-1. Dedicated Circuits Backup Configuration

Dedicated circuit backup allows the user to configure the ATLAS to dial up
a backup link when the dedicated link goes into alarm. Additionally, the AT-
LAS Nx 56/64 V.35 and USSI modules can rob an inband 8kbps channel over
which messages can be transferred. When the ATLAS loses communication
with the remote site, backup will be initiated. This feature is compatible
with the Inband Mode of the ADTRAN TSU series of products.
Currently, dedicated circuit backup is supported only for Nx interfaces
(V.35 or USSI) nailed to T1s.
