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.
