CESwitch(config)# interface cbr 3/0/0
Command
Purpose
Step 1
Switch(config)# interface cbr card/subcard/port
Switch(config-if)#
Selects the physical interface to be configured.
Step 2
Switch(config-if)# shutdown
Disables the interface.
Step 3
Switch(config-if)# ces circuit circuit-id [cas]
[on-hook-detect pattern]
[on-hook-detect pattern]
Configures channel-associated signalling and

on-hook detection on the CES circuit.
Step 4
Switch(config-if)# no shutdown
Reenables the interface.
