INFORMATION

Overview

This protocol converter (interface converter) using large scale FPGA design, providing a framing E1 interface and an Ethernet
interface and two serial interfaces, it is possible to achieve 10 / 100Base-T Ethernet data over E1 channels transmission, is a high performance,self-learning Ethernet bridge. The device
serves as an extension of Ethernet devices, use of existing networks (PDH / SDH / microwave, etc.) provided by the E1 channels
to interconnect both ends of the lower cost Ethernet and serial interfaces. Built-loop
test equipment capabilities to facilitate the opening and routine maintenance works.

Ø  Based on self -copyright  IC

Ø  Can realize monitor and control of remote equipment, OAM
management data did not  take up user’s timeslot and save E1 bandwidth

Ø  E1 supports any timeslot set, the rate is 64K-2048K

Ø  The local device can forced the remote device rate follow it

Ø  Have indicator  when the remote device is power-off or
E1 line is broken or lose signal;

Ø  Have the function of E1 interface loop back check, avoid the
converter crashed because of interface loop return;

Ø  The Ethernet interface supports jumbo frames (2036 Bytes);

Ø  Inter-set dynamic Ethernet MAC address (4,096) with local
data frame filtering function

Ø  Ethernet interface supports 10M/100M, half/full duplex auto-
Negotination, support VLAN

Ø  Ethernet interface supports AUTO-MDIX (crossed line and
straightly connected line self-adaptable );

Ø  Have Ethernet monitor self-reset function, the equipment
will not dead

Ø  Provide 2 clock types: E1 master clock and E1 line clock;

Ø  Provide 2 impedances: 75 Ohm unbalance and 120 Ohm
balance; 

Ø  Support SNMP Network Management 

Ø  Serial Data Interface can be RS232/RS422/RS485/TTL optional

Ø  Serial channel can transmit adaptable serial data
asynchronously 300 Kbps-14.400Kbps baud rate 

Ø  Serial data multiplexing in E1 support ITU-T R.111 jumping
coding mode

Ø  The local RS232 serial data can command the remote RS232
serial data loop-back to the local. This loop-back in the outer ring of
RS232 data interface, you can test the RS232 interface chip without damage

Ø  Serial port interface lightning-protection reached IEC61000-4-5
(8/20μS) DM(Differential
Mode): 6KV, Impedance (2 Ohm), CM(Common Mode): 6KV, Impedance (2 Ohm)
