E1 to Ethernet Protocol Converter, Interface Converter
8E1 to 4 x10/100 Ethernet converter, GFP supported
Spotlight:
This converter provides conversion from 1 to 8 E1 channels to 4 Ethernet interface with built-in switch. Support 1 to 8 E1 channels setting, it can detect the number of E1 channel and select available channel. It can reach 16.384 Mbps bandwidth when 8 E1 channels work simultaneity. Transmit Ethernet signal (RJ45) via point-to-point to remote RJ45 interface, realize connection between E1 channel and Ethernet, and compose bridge. Can satisfy real-time video, audio, and data transmit.
PRODUCT CHARACTER:
(1) IP traffic encapsulation based on: G.7041 GFP, G.7042 LCAS, G.7043 VCAT, G.8040 GFP over PDH
(2) 4 Ethernet transmit transparent through 1-8 E1 channels with built-in switch.
(3) Ethernet interface 10M/100M, full/half duplex configure by dip switch or self-negotiation,.
(4) Support AUTO-MDX/MDIX, straight and crossover auto-adapt.
(5) E1 interface according with ITU-T G.703,G.704,and G.823, not support the use of signaling time slot.
(6)E1 interface have built-in clock resume circuit and HDB3 codec circuit.
(7) Local and remote loopback supported.
(8)Support 1-8E1 channel hot plug, and auto detection available E1 channels for distributed bandwidth.
(9)Support flexible setting of 1 to 8 E1 channels, auto detect the number of E1 channels and time-delay, select available E1 channels when reset.
(10) Low power consumption, less than 5W
(11)Have Ethernet monitor self-reset function, device will not dead.
(12) 75 Ohm or 120 Ohm E1 optional. Both AC and DC power input.
(13)Support CRC error code threshold configuration 1x10e-6 for E1 line. The system will automatically switch off and isolate an E1 line if the error code rate of the line exceeds the configured threshold.
(14) LOS and CRC alarm limitation can auto insulate bad quality transmit channels 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).
(15) LED indicators: Power, E1 to E8 LOS (Loss of signal), FL (Frame Loss) or Remote Fail (AIS Alarm Indication Signal – flashing led), Ethernet 1 to 4 Link, Ethernet speed (SPD 10/100).
