以下是使用E1线路实现多个64Kbit/s专线连接。
当链路为T1时，channel-group编号为0～23，Timeslot范围为1～24；当链路为E1时， channel-group编号为0～30，Timeslot范围为1～31。
路由器具体设置如下：
Current configuration:
version 11.2
no service udp-small-servers
no service tcp-small-servers
!
hostname router1
!
enable secret 5 $ 1 $ XN08 $ Ttr8nfLoP9.2RgZhcBzkk/
enable password cisco

framing NO-CRC4
channel-group 0 timeslots 1
channel-group 1 timeslots 2
