Framed E1-FE+4RS232 Converter

Type:FCC-E1F1R4 Message

Description:1channel framed E1 -FE +4RS232/422/485 converter，With E1 loopback detection function

Product Description
                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;

Functional Properties

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-19200Kbps 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) standard
