4 E1 to 2 Ethernet interface protocol converter
GENERAL INFORMATION
This convertor provide conversion from 1 to 4 E1 channels to 2 Ethernet interface with built-in switch. Support 1 to 4 E1 channels setting, it can detect the number of E1 chnanel and select available channel. It can reach 8.192 M bandwidth when 4 E1 channels works simultaneity. transmit Ethernet signal (RJ45) via point-to-point to remote RJ45 interface, realize connection between E1 channel and Ethernet, compose bridge. Can satisfy real-time video, audio, and data transmit.
PRODUCT CHARACTER:
(1)Based on self–copyright IC.
(2)2 Ethernet transmit transparent through 1-4 E1 channels with built-in switch.
(3)Ethernet interface 10M/100M, full/half duplex self-adapt,support VLAN.
(4)support AUTO-MDIX, straight and crossover auto-adapt.
(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)4 E1 can have 10 ms transmissin delay, auto stop transmission when the delay above the limitation.
(7)Provide 2 loop functions: local E1 loop, remote E1 loop.
(8)MAC address capability:4096
(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 4 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.
