    DXC01

    EB-DXC01-ETH, make n timeslots (n<31) picked up from up-link E1 signal insert to homologous timeslots of down-link, let received ETH data take up residual timeslots of down-link, and can apply with E1/V.35-ETH converter to realize that down-link device picks up ETH data and V.35 data from E1. Also, it achieves the net structure of (EB-DXC01-ETH) ---- (E1 Fiber Modem) ---- (FMO-V35-ETH).

    1.1 Description

    EB-DXC01-ETH, make n timeslots (n<31) picked up from up-link E1 signal insert to homologous timeslots of down-link, let received ETH data take up residual timeslots of down-link, and can apply with E1/V.35-ETH converter to realize that down-link device picks up ETH data and V.35 data from E1. Also, it achieves the net structure of (EB-DXC01-ETH) ---- (E1 Fiber Modem) ---- (FMO-V35-ETH).

    EB-DXC01-ETH is suitable for telecom, post, public security, bank and so on.

     

    1.2 Characters

    n  Based on self-copyright IC;

    n  10M/100M Ethernet, full/half duplex self adapt, support VLAN.

    n  Ethernet support AUTO-MDIX (cross over and straight through self adapt)

    n  Support 3 kind loop functions: down-link E1 self-loop (ANA), up-link E1 loop back (DIG), command loop back of remote V.35 and ETH interface (REM);

    n  Have the function of pseudo-random code testing, which brings great convenience for installation, debugging and maintenance of equipment, and can be used as an E1 miscode tester;
