IDM TRX-4E1net Bridge

Overview:

The IDM TRX-4E1net Bridge is a protocol converter independently developed by our company using inverse multiplexing technology. This device bundles multiple E1 lines to transmit 10M/100M Ethernet data, enabling mutual conversion between 4 E1 channels and an Ethernet interface, with a maximum Ethernet transmission bandwidth of up to 7.92M.

The IDM TRX-4E1net Bridge can be used in various applications such as LAN interconnection, central office interconnection, video-on-demand, remote surveillance, and E1 interface line cards for switches, fully utilizing the abundant existing E1 resources in telecommunications networks to extend the transmission distance and application scope of Ethernet.

Technical Specifications:

Implements inverse multiplexing from 4 electrical Ethernet ports to 4 E1 lines;

Supports TAG VLAN configuration;

Supports E1 line delay difference detection, with a maximum relative delay of 220ms between E1 lines;

Transparently transmits jumbo frames as defined by IEEE 802.1Q, supporting Ethernet switches with VLAN functionality;

Automatically removes faulty E1 channels (with LOS, AIS, LOF, and other alarms) and automatically restores them when faults are cleared;

Supports network management based on RS232 serial port and SNMP, allowing monitoring of device operation status and configuration of device working states.
