IDM TRX-8E1net Bridge

Overview:

The IDM TRX-8E1net Bridge is a protocol converter independently developed by our company using inverse multiplexing technology. This device bundles multiple E1 channels to transmit 10M/100M Ethernet data, realizing mutual conversion between 8 E1 channels and an Ethernet interface, with a maximum Ethernet transmission bandwidth of up to 15.84M.
The IDM TRX-8E1net Bridge can be used in various scenarios such as LAN interconnection, central office interconnection, video-on-demand, remote surveillance, and E1 interface expansion cards for switches, fully utilizing the abundant existing E1 resources in telecommunication networks to extend the transmission distance and application scope of Ethernet.

Product Features:
   Supports GFP-F encapsulation format, compliant with ITU-T G.7041 standard;
   Automatically detects the number of available channels in E1 lines and allocates bandwidth;
   Supports asymmetric applications with non-corresponding E1 sequence numbers and unequal E1 quantities in transmit and receive directions;
   Supports 2M line loopback function;
   Implements inverse multiplexing from 3 electrical Ethernet ports to 8 E1 channels;
   Supports TAG VLAN configuration;
   Supports delay difference detection between E1 lines, 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 alarms, etc.) and automatically restores them when faults are cleared;
   Supports network management based on RS232 serial port and SNMP, enabling monitoring of device operation status and configuration of device working states.
