This convertor provides conversion from 1 to 4 E1 channels to Ethernet interface. Support 1 to 4 E1 channels setting, it can detect the number of E1 channel and select available channel. It can reach 8.192 M bandwidth when 4 E1 channels work 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:

• Based on self–copyright IC.
• Ethernet transmit transparent through 1-4 E1 channels.
• Ethernet interface 10M/100M, full/half duplex self-adapt,support VLAN.
• Support AUTO-MDIX, straight and crossover auto-adapt.
• 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.)
• 4 E1 can have 10 ms transmissin delay, auto stop transmission when the delay above the limitation.
• Provide 2 loop functions: local E1 loop, remote E1 loop.
• MAC address capability:4096
• E1 interface according with ITU-T G.703,G.704,and G.823,not support the use of signaling time slot.
• E1 interface have built-in clock resume circuit and HDB3 codec circuit.
• Support E1 channel hot plug, and auto detect available E1 channels.
• 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.
• Support reset remote system from local system.
• Have Ethernet monitor self-reset function, device will not dead.
• Network manager interface use SNMP
• Two types:Standalone, desktop, 19inch;Card,usually be inserted in our rack 19 inch.
