Defining the APS Fault-tolerant PVC/Resilient UNI Configuration
If the working port fails, the APS fault-tolerant PVC/resilient UNI software 
automatically moves the Service Name endpoint to the protection (backup) port. Use 
the following instructions to define the APS fault-tolerant PVC/resilient UNI 
configuration between two working ports:
1. Complete the steps described in “Creating Service Names” on page 14-4 to assign 
a Service Name to one of the working/ATM UNI logical port endpoints. A 
different Service Name must be used if backing up the working APS port on the 
other side of a fault-tolerant PVC.
2. Continue with the instructions in “Defining a Point-to-Point Circuit Connection” 
on page 10-13 to configure the fault-tolerant PVC.
