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;
n Power supply, AC220V, DC-48V, DC24V etc. modes for option;
n When in mode of DC-48V/DC24V, connection of power supply cathode and anode can not affect device working;
n Support SNMP net management function.
