Bộ chuyển E1 sang Ethernet và RS232 là sự lựa chọn tuyệt vời để truy cập internet cũng như các dịch vụ LAN-to-LAN

Tính năng

• 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
