ACS406CS

4 x E1/T1 Reference Design

Revision 1.5 February 2000

Advanced Communications

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.

·^{4 independent E1/T1 channels, configurable via}

switches.

·Full diagnostic modes available per channel via

switches.

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

·Incorporates Line Termination transformers and LIUs

with Line Protection.

block diagram of the complete system is given in Figure ·Screw termination blocks for twisted pair line

terminations.

·LEDs to indicate lock status and loss of line signals.

·On-board oscillator for 1.544/2.048MHz.

·Support for single wavelength Laser Duplex Device.

·Single 5V supply connection.

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.

·Board dimensions 100mm x 90mm.

On board LED indicators identify locking conditions and

transmission errors in both directions. The board

provides terminals for both power and line interface

connections.
