Product function: E1-2/4V. 35 (providing conversion from ITU-T G. 703 standard E1 to 2/4 V. 35 and 1 RS232 interface)
Product introduction:
E1-2/4V35 provides physical conversion between ITU-T G. 703 standard E1 interface and 2/4 standard V. 35 interfaces as well as one RS232 data channel. 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.

Features:

• realizes long-distance monitoring of this end equipment to the far-end equipment (two-row indicating lamp, upper row indicating local status, lower row indicating far-end status.)
• has Console port and supports super terminal control device;
• realizes random time slot choice from 31 slots with hardware;
• provides four clock types: E1 master clock, E1 line clock, V. 35 master clock, V. 35 external clock;
• provides 3 kinds of loop-return function, namely E1 self-looping at local end, V. 35 self-looping at local end, and V. 35 being ordered to self-loop at remote end;
• has the function of pseudo-random code testing; convenient for opening of the circuit; and can be used as an error code instrument;
• E1 supports rate of N*64k (N=1-32) , which can be regulated from 64K to 2048K;
• supports 75ohm unbalanced and 120ohm balanced impedance at the same time;
• V. 35 interface supports hot plugging and DTE and DCE interconnection;
• RS232 channel can transfer asynchronous serial data with self-adaptable baud rate of 300 to 19200;
• network management interface uses SNMP
