请教CISCO2811C/K9路由器添加 HWIC-2FE板的问题

[jialingwang4038]

请教大神：CISCO2811C/K9路由器（配置如下）有2块VWIC3-2MFT-G703 板卡，四个外网口连外部专线，外部专线可以访问内网口（interface FastEthernet0/0，ip address 172.16.10.20 ）的服务器，小白对接口卡不了解，不清楚controller E1 和channel-group是什么作用。
现在新安装了2条外部专线，所以我添加了一块 HWIC-2FE板卡，2个外网口（interface FastEthernet0/0/0和interface FastEthernet0/0/1）链路已连通，请问新的板卡还需要其他配置吗？如controller E1 和channel-group吗？外部专线可以访问内网口吗？（interface FastEthernet0/0，ip address 172.16.10.20 ）

谢谢！！

关于E1 ，通常使用语音的功能，会涉及这部分内容的配置。
欧洲的30路脉码调制PCM简称E1，速率是2.048Mbit/s 。
我国采用的是欧洲的E1标准。

关于E1的内容，更多的可以参考如下链接，思科同事总结过

https://community.cisco.com/t5/%E5%8D%8F%E4%BD%9C%E6%96%87%E6%A1%A3/e1-t1-isdn-pri-pra%E7%9A%84%E7%90%86%E8%A7%A3/ta-p/4336892

关于channel-group则是在该controller上的编号，例如：

interface serial 0/subslot/port:channel-group

Example:

Router(config)# interface serial 0/0/1:0

Example:

Selects the interface to configure from global configuration mode.

• subslot —Specifies the subslot in which the T1/E1 interface module is installed.
• port —Specifies the location of the controller. The port range for T1 and E1 is 1 to 16.
• channel-group —Specifies the channel group number configured on the controller. For example: interface serial 0/0/1:1.

如果只是路由交换的功能实现，应该是不需要对E1接口和其Channel进行配置的。
