显示e1模块（Display E1 module） CE1 can divide slot. CE1 each time slot is 64K, a total of 32 time slots, when used, can be divided into n*64K, such as: 128K, 256K, and so on. CE1 0 and 15 time slots is not to transmit the users data flow, 0 slot is No. 15 slot synchronization, transmission control signal, only 30 slots that can be used in practice, so the specific configuration of CE1 time slot division, should pay attention to some. CE1 and E1 can also be interconnected, but CE1 must be used as E1, i.e., an integral slot. Because CE1 is more flexible, we can often run into CE1. HUAWEI AR4640 E1/CE1 configuration summary (original) HUAWEI AR4640 Usage Summary [img]/upload/stock/S15180_562840.jpg[/img] HUAWEI AR4640 Today, the XX unit network transformation uses the modules used by HUAWEI AR4640., two modules of RT-FIC-8E1 (75), -F and RT-FIC-8E1 (75) RT-FIC-8E1 (75) -F 8 E1 line card interface connection can not be divided into many group of time slots used. This interface is the best, not of each time slot, each directly using 2M. without wasting bandwidth. (because each line can only receive 2M). If you use a few time slots a line in this line. Then you can only use this several time slots. Good time slot are free wave. RT-FIC-8E1 (75) finally, without F., this interface card is divided into time slots. Each slot in the 2M circuit can use the part. The remaining part of the slot can be reserved for use For the configuration of the E1 interface First of all. Activate the features of E1 Configuration of RT-FIC-8E1 (75) cards huaweiSystem [huawei]controller E1 1/0/0...... Corresponds to the first E1 line in the private connection line on the 8E1 card (including 0-TX, 0-RX) The controller E1 1/0/1 corresponds to the second E1 lines (1-TX, 1-RX) [huawei]using CE1... ... Using channel E1 (E1 that can divide slot), the default is using E1 (non separable slot) in general For RT-FIC-8E1 (75) -F cards, you can use them directly [huawei]channel-set 1, timeslot-list 1, after this
