General Information:
This product is related to a distribution module with splitter for
the effective processing of user signal and ADSL signal in
broadband data communication products.
Background:
There are two kinds of outgoing cables from the back of the current
broadband data communication products. One is for the
connection to subscriber cables and the other is for the
exchange. As channels for information transmission in large
quantity, they play an important part in such equipment.
However, studies have found the following problems:
1.A large amount of splitting and protection devices have to be
located on subscriber board. Splitters are used for the
separation of low-frequency audio signal (under 138KHz) and
high-frequency transmission signal (138KHz-12MHz) so that they
won’t interfere with each other. The protection devices keep
the broadband data products from being damaged by lightening
strokes or lapping of power lines. These passive devices take
up a lot of space on the subscriber board and keeping its density
at a low level. This can increase the cost to be shared by
the single boards and possibly add difficulty to market promotion.
2.There are cables for the connection with both subscriber line and
exchange coming from the back cover of the equipment. Two
different wire jumping operations for two distribution modules can
bring a lot of trouble to installation and maintenance.
Product Design:
As a solution to the problems, this product offers a distribution
module with built-in splitter to enhance the reliability, stability
and styling. The design presents an improvement due to its
lower cost, simpler installation and maintenance, less design
repetition and easier management.
The distribution module carries 8 subscriber access units, each
of them is connected to the data processing module through
the protection device on the subscriber board. Each
subscriber access unit also includes an inner jumper terminal, a
subscriber jumper terminal, an exchange jumper terminal and a
splitter.
Through the subscriber jumper terminal, inner jumper terminal and
protection device, the subscriber cables are connected to the data
processing module. The splitter is connected with the
exchange jumper terminal at one end and the line between the
subscriber jumper terminal and inner jumper terminal at the
other. After the splitting of signals, the low-frequency
signals are sent to exchange by way of exchange jumper terminal.
Features:
8 different lines for each module;
Separation of analog audio channel and high-frequency digital
channel;
Compact design;
Testing terminals available;
Modem function;
Over voltage protection
In comparison with other technology in current use, our innovation
includes optimized module design to achieve the following
improvements:
Substantial increase of the density of subscriber board on
broadband data communication device resulting in higher cost
effectiveness;
Fewer protection devices and reduced cost of the product;
Simpler installation and maintenance due to fewer outgoing cables
