E1-V35 provides physical conversion between ITU-T G.703 standard E1 interface and 2 standard V.35 interfaces. It can provide safe and seamless communication connection between equipments with different interfaces in the network. Random time slot can be chosen in G.703 standard E1 to compose V.35 channel with the rate of N*64K(N=1-32).
It is suitable for the case that part slot of E1 channel can be used and the equipment transmitting data only has V.35 output. The mode of data interface is DCE, which can be connected with DTE or DCE equipment. RS232 channel can transfer asynchronous serial data with self-adaptable baud rate of 0 to 19200 and can also transfer Console data from remote-end equipment such as Router.
The equipment supports super terminal control device with Console port. Equipment at local end can be self looped and configure console port of remote-end device through RS232 channel. Application field: DDN circuit extends through E1 channel.
