Chpater 1 General Information
1.1 Introduction
OP-4E1+ETH+32Vo is a new generation highly-integrated
single-board PCM base group multi-connection equipment based
on independent software and thick & thin film technology. It can
provide a 4~32-line voice interface directly upon the optical
transmission channel with a 4-line E1 interface, a 4-line(100M
shared) Ethernet data interface. Voice Broadband Optical
Multiplexer is mainly used in implementing connections between
telephones and SPC exchanges through transmission network, as
well as providing various kinds of data operation interfaces.
The device is widely used in: places such as telephone bars,
middle and small scale companies, expressways and some
temporary construction sites which demand quick solutions to the
need of telephone and data operation, and the “Village-village
Connection” telephone accessing project which is now in
progress.
1.2 Features

reliability, easy installing&commissioning, maintenance free
and stable performance.
Fiber interface provides optical circuit E-3 and E-6 bit error
warning detection, indicating circuit quality for builders and
helping circuit maintenance.
4-line E1 interface to help extend telephone interfaces or
other video transmission.
32-line telephone interface, traditional PSTN voice,
uncompressed, with high voice quality. Caller ID function
available.
4-line Ethernet interface with 100M bandwidth. Optional
10M/half duplex, 10M/full duplex, 100M/half duplex,
100M/full duplex and self adaptative.

customer.
2.2.4 Power Supply
The power supply has two options: AC and DC, which
should be specified upon ordering, and a universal version is also
available. The device supports two power versions: 220V and
–48V, with up to 20% fluctuation. Note that the DC power supply
has positive and negative poles. The negative/positive pole of
–48V power source should be plugged into the negative/positive
pole of the power input on the device. The power is off when
the switch is on “OFF” position. Otherwise the power is on.
