E1 to Ethernet and RS232 converter

E1 to Ethernet and RS232 converter could Plugging directly into the 10/100Base-T port of a hub or LAN switch, the E1 to Ethernet converter provides FE1 access at connection data rates of 2.048 Mbps, or nx64 (n=1 to 32 channels). The E1 to Ethernet and RS232 converter is an excellent choice for internet access as well as LAN-to-LAN services

PRODUCT CHARACTERISTIC

Have two row of LED , one indicate local status, the other indicate remote status

Remote adjustment of velocity for the remote device is available, you can set the velocity of one side, and the velocity of the other side can auto adjust.

Based on FPGA, easy to upgrade

Ethernet port support AUTO- MDIX( straight line and crossed line adapt); the interface of LAN is 10/100M ,full/duplex auto-negotiation

LAN interface support 802.1Q(VLAN) protocol

Provide two clock mode, E1 main clock and E1 line clock

Have three LoopBack Mode: E1 interface LoopBack(ANA)¡￠LAN interface/RS232 LoopBack(DIG)¡￠command the remote LAN interface/RS232 LoopBack (REM)

E1 port support BNC 75-ohm dual coax and RJ45 120-ohm twisted-pair G.703 connections provided, support 75ohm/120ohm adapt;

Support PBRS test function and it could use as a error code device;

RS232 channel can transfer asynchronous serial data with self-adaptable baud rate of 300 to 19200;

220VAC & -48VDC power options and the positive and negative of DC-48V can be optional because there is the self-test circuit for the polarity inside the device
