4E1 to 4 Ethernet converter
This converter provides conversion from 1 to E1 channels to
4 Ethernet interface with built-in switch. Support 1 to 4 E1
channels setting, it can detect the number of E1 channel and select
available channel. It can reach 8.192 Mbps 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, and compose bridge. Can satisfy real-time
video, audio, and data transmit.

Specification
(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 1-4 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 1-4E1 channel hot plug, and auto detection available E1
channels for distributed bandwidth.
(9)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.
(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 E4 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).
