Each time slot of CE1 is 64K, and there are 32 time slots in total. The main difference between it and E1 is that E1 cannot divide time slots, while CE1 can divide time slots. The bandwidth of the transmission line of CE1 is 2048K. The E1 on the router cannot be divided into time slots and can only be used as a 2M line. This is the E1 that is said on the access server (such as Huawei 8010, Nortel’s CVX1800, etc.), and is somewhat different from the E1 concept usually said on routers. It is used to transmit control signaling, so one E1 can transmit 30 channels of voice. It uses one E1 as 32 64K, but time slot 0 and time slot 15. The most original use of E1 is when it is used as a digital relay of a voice switch. The following is the corresponding configuration displayįor e1 after the configuration is completed :įirst of all, I want to talk about the basic concepts of E1 and CE1. (The above process basically completes the E1 configuration, now you only need to shut the corresponding port and save the configuration)
Where 7-9 refers to a segment, you can use the same command to configure multiple channel-groups, but you need Note thatĬhannel-group corresponds to different numbers, and a time slot cannot be included in multiple groups) Specific The configuration process is as follows: Router#conf t Router(config)#controller e1 4/0 Router(config-controller)# Router(config-controller)#framing NO-CRC4 Router(config-controller)#channel-group 0 timeslots 1 ( 1 slot configured to channel-group 0, i.e., channel-group 0 contains slots 1, its band width is on 64K) Router (config-Controller) Channel-Group # 1 timeslots 2,7-9,20 time (configuration Slots 2, 7, 8, 9, 20 are channel-group 1, and its bandwidth is 64 5=512K, In this example, serial4/0:1 has a data rate ofĥ 64Kbps.

Suppose it is a 7500 series router, and the E1 interface (MIP board) is on slot 4.Ī channel-group can correspond to multiple time slots.
