1.Controller Configuration Examples控制器配置举例
The following example shows a typical controller configuration for
the multichannel E1/PRI port adapter on a Cisco 7200 series or
Cisco uBR7200 series router:
router enable
router# configure terminal
router(config)# controller E1 1/0
router(config-controller)# framing crc4
router(config-controller)# linecode hdb3
router(config-controller)# clocksource internal
router(config-controller)# channel-group 0 timeslots 1-31
router(config-controller)# description ppp channel 5
router(config-controller)# shutdown
router(config-controller)# ^Z
2.Interface Configuration Examples接口配置举例
The following example shows a typical interface configuration for
the multichannel E1/PRI port adapter on a Cisco 7200 series or
Cisco uBR7200 series router:
router enable
router# configure terminal
router(config)# interface serial
router(config)# interface serial 4/1:0
router(config-if)# encapsulation ppp
router(config-if)# description ppp channel 5
router(config-if)# no shutdown
router(config-if)# ^Z
3. Configuring Multichannel E1 Interfaces 配制多通道E1接口
The channel groups must be mapped before the multichannel E1/PRI
controller can be configured. The following are controller commands
used to map the channel group (the default variable is listed first):
controller E1 port-adapter-slot number/port-number (for Cisco 7200
series router)
clock source [line internal]
linecode [ami hdb3]
framing [crc4 no-crc4]
loopback [diagnostic local {payload line}]
shutdown
channel-group number timeslots list
Number is the channel group 0 to 30.
list is a number between 1 and 31. You can enter timeslots individually
and separate them by commas, or enter them as a range separated by
a hyphen (for example, 1-3, 8, 9-18). Timeslot 0 is an illegal
configuration.
