E1 to Ethernet Protocol Converter, Interface Converter
2E1 to 2*Ethernet Converter
GENERAL INFORMATION：
1) Converts signals between (1~2) E1 interface and Ethernet interface and transmits video, voice, data and so on with Max. Bandwidth be 3.968Mb (2 E1).
2) Get the connected Mac adds. Continuously and determine whether frames can be forwarded or filtered according to MAC destination address of data frames
3) Supports limitation setting of CRC error code for each E1 interface. When error code rate is beyond the limitation, the system can automatically isolate the E1link.
4) Local loop back function available (2 E1 channels are looped together.)
PRODUCT CHARACTER:
(1) Based on self–copyright IC.
(2) 2 Ethernet transmit transparent through 1-2 E1 channels with built-in switch.
(3) Ethernet interface 10M/100M, full/half duplex self-adapt,support VLAN.
(5) CRC alarm limitation can auto insulate bad-quality transmit channel by configuration, and is single direction insulation. when one direction error rate over limitation, cut only this direction, the other direction not affected.( the two directions need not symmetry.)
(6) 2 E1 can have 32 ms transmissin delay, auto stop transmission when the delay above the limitation.
(7) Provide 2 loop functions: local E1 loop, remote E1 loop.
(9) E1 interface according with ITU-T G.703,G.704,and G.823,not support the use of signaling time slot.
(10) E1 interface have built-in clock resume circuit and HDB3 codec circuit.
(11) Support E1 channel hot plug, and auto detect available E1 channels.
(12) Support flexible setting of 1 to 2 E1 channels, auto detect the number of E1 channels and time-delay, select available E1 channels when reset.
(13) Support reset remote system from local system.
(14) Have Ethernet monitor self-reset function, device will not dead.
