Configuring T1/E1 Structured (n x 64) Circuit Emulation Services
Phase 1—Configuring the Destination (Passive) Side of a Soft PVC
To configure a destination (passive) side of a soft PVC for structured CES, follow these steps, beginning
in privileged EXEC mode:
Command Purpose
Step1 Switch# show ces status Displays information about the current CBR
interfaces. Use this command to choose the
destination port.
Step2 Switch# configure terminal
Switch(config)#
At the privileged EXEC prompt, enters global
configuration mode.
Step3 Switch(config)# interface cbr card/subcard/port
Switch(config-if)#
Selects the physical interface to be configured.
Step4 Switch(config-if)# shutdown Disables the interface.
Step5 Switch(config-if)# ces aal1 service {structured |
unstructured}
Configures the CES interface AAL1 service type.
Step6 Switch(config-if)# ces dsx1 clock source
{loop-timed | network-derived}
Configures the clock source.
Step7 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. For
CES E1, the default is e1_lt.
Step8 Switch(config-if)# ces dsx1 linecode {ami | b8zs}
Switch(config-if)# ces dsx1 linecode {ami |
hdb3}
Configures the CEST1 line code type. The
default is b8zs.
Configures the CESE1 line code type. The
default is hdb3.
Step9 Switch(config-if)# ces circuit circuit-id 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.
•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.
Step10 Switch(config-if)# ces circuit circuit-id
circuit-name name
Configures the CES interface circuit name.
