4 x E1/T1 Reference Design
Advanced Communications
Revision 1.5 February 2000
4 x E1/T1 Channel Mux/Demux Chip Set over Fiber Optic Cable
DESCRIPTION
FEATURES
The ACS406CS Reference Design is a full featured 4 x
E1/T1 point to point fiber mux/demux including Line
Termination transformers and Line Interface Units (LIU)
utilising the ACS406CS chip set.
This document contains the circuit description,
schematics and BOM for a typical custom application of
the ACS406CS chip set with a Quad LIU. A simplified
block diagram of the complete system is given in Figure
3.
The Reference Design can be configured for either 4 x
E1 or 4 x T1 independent channel operation via a Jumper.
An on board oscillator is used to generate 1.544/
2.048MHz. Independent control of the channel diagnostic
modes can be selected by switches.
On board LED indicators identify locking conditions and
transmission errors in both directions. The board
provides terminals for both power and line interface
connections.
路
4 independent E1/T1 channels, configurable via
switches.
路
Full diagnostic modes available per channel via
switches.
路
Incorporates Line Termination transformers and LIUs
with Line Protection.
路
Screw termination blocks for twisted pair line
terminations.
路
LEDs to indicate lock status and loss of line signals.
路
On-board oscillator for 1.544/2.048MHz.
路
Support for single wavelength Laser Duplex Device.
路
Single 5V supply connection.
路
Board dimensions 100mm x 90mm.
