We are offering e1 to ethernet protocol interface converter. cl-c1200l/c1200/c1400/c1100/c1101 fe1 to 10/100base-tx/fx ethernet protocol interface converter is an ethernet bridge of high performance, which accomplishes the converting between the 100m ethernet port and the e1 port. It can automatically learn the mac addresses in the linked lan continuously, and transmit the aim address to frame in another lan. There are up to 10, 000 addresses in its lan sheet, which can be updated automatically. The maximum rate of transmitting and filtrating is 30, 000 frame/second (line speed), with the buffer capable to contain 256 frames and waiting throughput 1 frame. Specified time slot can be extracted from g.703 e1 at discretion to compose the data channel for n*64k (n=0~31).the device is furnished with lcd display panel, on which both check and configuration can be fulfilled through operational keys. As an extended device of the ethernet, the fe1-10/100base-tx bridge realizes interconnection of two ethernet by using the e1 channel provided by existing networks with low cost.

We are offering fiber optic modem. Cl-fom100/fom135/fom100s/fom135s fiber modem can modulate g.703 e1 or v.35 signal to single-mode or multimode fiber which extend the transmitting distance of e1 signal greatly. E1 signal support framed and unframed mode. When in framed mode, continuous or discontinuous time-slot can be selected. E1 fiber modem and v.35 fiber modem can be used together. Both of them are widely used in extending user interface in atm or ddn.standalone and rack mount module are both available.
