Chapter 19 Configuring Circuit Emulation Services
Configuring CES T1/E1 Interfaces
• Sets the ASCII name for the CES-IWF circuit.
The maximum length is 64 characters. The
default is CBRx/x/x:0.
• Enables the partial AAL1 cell fill service for
structured service only. The default is 47.
• Disables the circuit. The default is no
shutdown.
• Configures the time slots for the circuit for
structured service only.
• Configures on-hook detection.
Step 6
Switch(config-if)# ces dsx1 clock source
{loop-timed | network-derived}
Configures the clock source. The default is
network-derived.
Step 7
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 CES T1 framing mode. The default
is esf.
Configures CES E1 framing mode. The default
is e1_lt.
Step 8
Switch(config-if)# ces dsx1 lbo {0_110 | 110_220
| 220_330 | 330_440 | 440_550 | 550_660 |
660_above | square_pulse}
Configures the line build-out. The default is 0_110.
Step 9
Switch(config-if)# ces dsx1 linecode {ami | b8zs}
Switch(config-if)# ces dsx1 linecode {ami |
hdb3}
Configures CES T1 line code type. The default
is b8zs.
Configures CES E1 line code type. The default
is hdb3.
Step 10
Switch(config-if)# ces dsx1 loopback {line |
noloop | payload}
Configures the loopback test method. The default
is noloop.
Step 11
Switch(config-if)# ces dsx1 signalmode
robbedbit
Configures the CES T1 signal mode to robbedbit.
The default is no.
Step 12
Switch(config-if)# ces pvc circuit-id interface
atm card/subcard/port [vpi vpi] vci vci
Configures the destination port for the circuit and
configures a hard PVC, as follows:
• Specifies the circuit identification.
–
For unstructured service, use 0.
–
For T1 structured service,
use 1 through 24.
–
For E1 structured service,
use 1 through 31.
• Specifies the card/subcard/port number of the
ATM interface.
• Specifies the virtual path identifier of the
destination PVC.
• Specifies the virtual channel identifier of the
destination PVC.
