   BD-E1-ETH is a single port G.703 E1 to Ethernet converter (also called Ethernet over E1 TDM converter,G703 to ethernet converter) that provides high-speed LAN-to-WAN connectivity. Plugging directly into the 10/100Base-T port of a hub or LAN switch, the BD-E1-ETH provides E1 access at connection data rates of 2.048 Mbps. The ethernet over E1 converter is an excellent choice for internet access as well as LAN-to-LAN services.

  The E1 to ethernet converter can support mini desk type case and 19" rack mount type case. The 19" rack mount E1 converter can support double power (two AC or two DC or AC+DC),which strength the operation stability.


   ●   Ethernet port 10/100M half/full duplex auto-negociation, supporting VLAN.

   ●   Ethernet port interface supports AUTO-MDIX.

   ●   Provides 2 clock types: E1 master clock, E1 line clock.

   ●   Provide LAN auto reset function, run more stably.

   ●   Has the function of pseudo-random code testing, convenient for opening of the circuit, and can be used as an error code instrument. 

   ●   Have three LoopBack Modes: E1 interface LoopBack (ANA),LAN interface LoopBack (DIG),command the remote LAN interface LoopBack (REM) .

   ●   E1 port support BNC(75ohm) dual coax and RJ45(120ohm) twisted-pair G.703 connections, and support 75ohm/120ohm adaptive ;

   ●   With abundant presentation function of Ethernet data, can detect real-time data communication status.

   ●   Can realize SNMP management in our chassis installation
