The DBU can activate backup in two basic modes: Single End Failure or Both End Failure: Single End Failure (Mode: ORIG/ANS.ANY) - In this mode, a network failure detected at either end of the circuit causes a backup to be activated. The DBU at the failed end initiates a call to the opposite end which goes into backup mode upon receiving a call.
- Page 24 Chapter 3. Operation 6. NUMBER DS0: (1-24) - The number of DS0s that are backed up is entered by using the numeric keypad on the front of the TSU 100/600. Verify that the two above settings do not exceed available bandwidth.
