    Overview:  

    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 G703 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.

     

    Features:

    • 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

    what is difference between TDM over IP and E1 to ethernet converter?

    Some customers often confuse in project:using TDM over IP or using E1 to ethernet converter?The document help to answer the question

    Introduction:
    Many users often confuse the difference between TDM over IP device and E1 to Ethernet converter device. Some users choose the wrong device in the project application. The document introduce the difference between TDM over IP and E1 to Ethernet converter.
    Key words: TDM over IP TDMOIP E1 over Ethernet E1 to Ethernet converter Ethernet over E1
    E1 to ethernet converter:
    E1 to Ethernet converter (also called E1 network bridge) is to transmit Ethernet data over E1 network (PDH,SDH network etc). The Ethernet port connect to terminal device,computer,Ethernet switch,Ethernet router etc. The device抯 E1 port connect to mail network(PDH SDH etc). The typical application as below.

    TDM over IP:
    TDM over IP (TDMOIP) is to transmit the E1 data over ethernet network. It transports the legacy E1 data through the existing Ethernet or IP network. The typical application is transmit voice and data over wireless radio network.
