Configuring CES Circuits for SGCP

Any single time slot (64 Kbps) allocated to a circuit on a CES T1/E1 interface can be configured for
SGCP with these restrictions:
•
•
Configuration on the call-agent can restrict the range of circuits designated for signalling on a CES
Note
circuit interface.
When you configure a CES circuit for SGCP, signalling should be given the proper time slot. For T1 CES
circuits, a time slot can be given a number from 1 to 24; for E1 CES, a number from 1 to 31.
Although no keyword identifies a CES circuit as allocatable by SGCP, there is normally a simple
configuration rule to ensure that signalling allocates the proper time slot:
The endpoint specifier used by SGCP refers to the CES circuit ID (not the time slot). If a time slot is not
Note
allocated to a circuit, that time slot cannot be used by SGCP (or CES, either).
To configure SGCP operation on a CES circuit interface, follow these steps, beginning in global
configuration mode:
Command
Step 1 Switch(config)# interface cbr card/subcard/port
Switch(config-if)#
Step 2 Switch(config-if)# ces aal1 service structured
Step 3
Switch(config-if)# ces circuit circuit-id
timeslot number
Example
The following example shows how to configure the CES port for structured CES with all time slots
available for SGCP. CES circuit 16 is configured for common channel signalling and specified as a soft
permanent virtual channel (soft PVC) to a circuit on the CES port adapter connected to the call-agent.
Switch(config)# interface cbr 1/1/2
Switch(config-if)# ces aal1 service structured
Switch(config-if)# ces circuit 1 timeslot 1
Switch(config-if)# ces circuit 2 timeslot 2
Switch(config-if)# ces circuit 3 timeslot 3
Switch(config-if)# ces circuit 4 timeslot 4
Switch(config-if)# ces circuit 5 timeslot 5
Switch(config-if)# ces circuit 6 timeslot 6
Switch(config-if)# ces circuit 7 timeslot 7
Switch(config-if)# ces circuit 8 timeslot 8
Switch(config-if)# ces circuit 9 timeslot 9
Switch(config-if)# ces circuit 10 timeslot 10
Switch(config-if)# ces circuit 11 timeslot 11
Switch(config-if)# ces circuit 12 timeslot 12
Switch(config-if)# ces circuit 13 timeslot 13

CES is not the active source end of a soft PVC.
CES is not part of a hard PVC.
circuit x is allocated time slot x, 1<=x<=24 (or 31 for E1).
