Product function:BD-8E1-4ETH converter uses reverse multiplexing technology to
transmit 10/100BaseT data with bonding multi E1 channels, thus
realizing conversion between 1-8 E1 channels and Ethernet
interface. It can transmit signals point-to-point from E1 channel
to RJ45 interface to realize connection between E1 channel and
Ethernet. Being different from general long-distance bridge, this
converter supports flexible configuration of 1 to 8 channels E1 and
can detect the number of E1 channel and choose available channel.
In the meantime, certain difference of transmitting delay is
allowed among E1 channels. Line rate is 1968Kbit/s for one E1
channel and bandwidth can reach 15744Kbit/s for 8 E1 channels. When
used in 10/100Mbps half/full duplex mode, this equipment can be
connected with Ethernet switch or hub (integrated circuit machine)
to expand transmitting distance and application scope of Ethernet
by making full use of large number of E1 channels in current
telecommunication network. The 8E1 to ethernet interface converter
is an excellent solution for connecting Ethernet broadband. This
product can be applied in many fields such as connection of LAN and
end offices, video ordering (VOD), remote monitor and E1 interface
of switches.
Features: - Realizes transparent transmission of Ethernet data in 1 to 8 E1
channels.
- Ethernet supports 10M/100M, full/half duplex auto-negociation,
supports VLAN.
- Ethernet port supports AUTO-MDIX (cross over and straight through
auto-adapt).
- Setting CRC alarm limitation to auto isolate lines with low
transmitting quality (being cut single-directionally); when error
code rate of one direction in 2M branch exceeds the limitation,
this direction is cut and the other direction will not be affected,
namely the two transmitting directions of Ethernet can be
unsymmetrical.
- Allow 8 E1 channels up to 10ms transmission delay. When the delay
exceeds allowed limit range, it can stop transmitting data
automatically.
- Has 2 loop back functions: E1 local loop, E1 remote loop.
- Supports Dynamic Ethernet MAC address (4096) with local address
filter function.
- E1 interface compatible with ITU-T G.703, G.704, and G.823. not
supporting signal timeslot.
- E1 interface has internal clock recover circuit and HDB3
code/decode circuit.
- Supports E1 channel hot plug, and auto detect effective E1 channels
data transmission will not be cut.
- Supports 1 to 8 E1 channels customized configuration, auto detect
the number of E1 channels and select the available E1 when
resetting.
- Supports resetting remote system from local system.
- Having Ethernet monitor auto reset function.
