Chapter 19 Configuring Circuit Emulation Services
Configuring T1/E1 Structured (n x 64) Circuit Emulation Services
Example
The following example shows how to configure multiple soft PVCs on the destination (passive) side of
the same port (shown in Figure 19-7):
CESwitch(config)# interface cbr 3/0/2
CESwitch(config-if)# shutdown
CESwitch(config-if)# ces aal1 service structured
CESwitch(config-if)# ces dsx1 clock source network-derived
CESwitch(config-if)# ces dsx1 framing esf
CESwitch(config-if)# ces dsx1 linecode b8zs
CESwitch(config-if)# ces circuit 2 timeslots 24 circuit-name CBR-PVC-CA
CESwitch(config-if)# no shutdown
Note If you do not specify the circuit name and logical name parameters in the command line, the system
automatically assigns a unique default name in the form CBRx/y/z:# for the circuit being configured. For
example, the default name for this particular circuit is CBR3/0/2:1. For structured circuit emulation
services, the circuit number sequence always begins at 1 for each port in a CES module.
Phase 2—Configuring the Source (Active) Side of Multiple Soft PVCs
To configure multiple soft PVCs on the source (active) side of the same port, follow these steps,
beginning in global configuration mode:
Command Purpose
Step 1
Switch(config)# interface cbr card/subcard/port
Switch(config-if)#
Selects the source interface to be configured.
Step 2
Switch(config-if)# shutdown Disables the interface.
Step 3
Switch(config-if)# ces circuit circuit-id
[circuit-name name] [timeslots number]
Configures the following CES connection
attributes for the circuit:
• Circuit id number.
–
For CES T1 structured service,
use 1 through 24.
–
For CES E1 structured service,
use 1 through 31.
• Configures the CES interface circuit name.
• Configures the time slots for the circuit for
structured service only.
–
For CES T1, the range is 1 through 24.
–
For CES E1, the range is 1 through 31.
Step 4
Switch(config-if)# no shutdown Reenables the interface.
Step 5
Switch(config-if)# end
Switch#
Exits interface configuration mode.
