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.
