16E1-4FE Interface Converter

View : 1,115
Type : Multi E1-Ethernet Bridge
Description :

This 16e1-4fe interface converter is based on FPGA, using reverse direction multiplexing technology to bundle multiple E1 circuits to transmit the Ethernet data of 100BASE-TX.


The 16E1-4FE converter is based on FPGA, and it uses reverse direction multiplexing technology to bundle multiple E1 circuits to transmit the Ethernet data of 100BASE-TX. It can realize conversion between E1 and Ethernet optical interface. This device can transmit the transceiver signal point to point to Ethernet optical interface to make E1 channels interconnected with Ethernet optical interface. Different from general remote network bridge, this device can support 16-channel E1 configuration, can automatically detect the number of E1, and select the E1 available. It allows E1 lines transmission time delay difference.

Based on self-copyright IC;

To achieve Ethernet data transparent transmission in 1-16E1 circuits;

Can realize the local and the remote device reset;

Ethernet Interface is 100BASE-FX, support VLAN protocol;

Inter-set dynamic Ethernet MAC address (4,096) with local data frame filtering function;

Single Channel lines rate is 1984Kbit/s, 4Channel Bandwidth is up to 7936Kbit/s;

Support all sets of Ethernet Work Mode;

CRC automatic alarm threshold can be set to isolate the poor quality transmission lines and cut off a single direction. When the 2M branch circuit one direction error rate exceeds the threshold, cutting off this direction the other direction is not affected; that is to say, both of the Ethernet direction transmission can be asymmetric;

Allow 16Channel E1 transmission time delay difference 100ms. When the margin exceeds the allowed range, the system can automatically stop on the E1 that time delay is too large to send data;

E1 interface conforms to ITU-T G.703, G.704, and G.823, not support the use of signal timeslot;

E1 interface module with inter-set clock recovery circuit and HDB3 code circuit;

Support E1 channel hot-plug in the device, and automatically detects the effective channel and will not interrupt data transmission;

Can support 1-8Channel E1 channel configuration, can automatically detect the number of E1 and select the E1 available;
