Chapter19 Configuring Circuit Emulation Services
Configuring T1/E1 Structured (n x 64) Circuit Emulation Services
Phase 1—Configuring the Destination (Passive) Side of Multiple Soft PVCs
To configure multiple soft PVCs on the destination (passive) 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 physical interface to be configured.
Step 2
Switch(config-if)# shutdown Disables the interface.
Step 3
Switch(config-if)# ces aal1 service {structured |
unstructured}
Configures the CES interface AAL1 service type.
Step 4
Switch(config-if)# ces dsx1 clock source
{loop-timed | network-derived}
Configures the clock source.
Step 5
Switch(config-if)# ces dsx1 framing {sf | esf}
Switch(config-if)# ces dsx1 framing
{e1_crc_mfCAS_lt | e1_crc_mf_lt | e1_lt |
e1_mfCAS_lt}
Configures the CES T1 framing type. The default
is esf.
Configures the CES E1 framing type. The default
is e1_lt.
Step 6
Switch(config-if)# ces dsx1 linecode {ami | b8zs}
Switch(config-if)# ces dsx1 linecode {ami | hdb3}
Configures the CES T1 line code type. The
default is b8zs.
Configures the CES E1 line code type. The
default is hdb3.
Step 7
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.
Note The 0 circuit identifier is reserved for
unstructured service.
• 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 8
Switch(config-if)# ces pvc circuit-id passive
follow-ifstate
Configures the destination (passive) port circuit
status to follow the status of the physical
interface. The default circuit setting ignores the
status of the physical interface.
Step 9
Switch(config-if)# no shutdown Reenables the interface.
