E1 To Ethernet Converter

framed E1-FE+4RS232 Converter

This interface converter is based on FPGA providing one framed E1 interface one Ethernet interface and 4 serial interfaces to achieve 10/100base-T Ethernet data transmission on the E1 channel.Providing  one Ethernet Bridge plus 4 serial interfaces via one E1 interface.
◆ based on self -copyright IC; 
◆ Can realize monitor and control of remote equipment OAM management data did not  take up user’s timeslot and save E1 bandwidth;
◆ E1 supports any timeslot set the rate is 64K-2048K;
◆ The local device can forced the remote device rate follow it;
◆ Have indicator  when the remote device is power-off or E1 line is broken or lose signal;
◆ Have the function of E1 interface loop back check avoid the converter crashed because of interface loop return;
◆ The Ethernet interface supports jumbo frames (2036 Bytes);
◆ Inter-set dynamic Ethernet MAC address (4096) with local data frame filtering function;
◆ Ethernet interface supports 10M/100M half/full duplex auto- Negotination support VLAN;
◆ Ethernet interface supports AUTO-MDIX (crossed line and straightly connected line self-adaptable );
◆ Have Ethernet monitor self-reset function the equipment will not dead;
◆ Provide 2 clock types: E1 master clock and E1 line clock;
◆ Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance; 
◆ Support SNMP Network Management; 
◆ Serial Data Interface can be RS232/RS422/RS485/TTL optional;
◆ Serial channel can transmit adaptable serial data asynchronously 300 Kbps-19200Kbps baud rate; 
◆ Serial data multiplexing in E1 support ITU-T R.111 jumping coding mode;
◆ 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;
◆ 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) standard.
