OVERVIEW

The TDS1 (

T

elephone 

D

ialup 

S

ystem - 1 line)  was originally designed to allow 

anyone to dial into a sound system and listen live to the program audio feed. In 
the AUTOmatic mode, the TDS will answer the first incoming telephone call 
and connect the caller to the audio.

 

In the MANual mode, calls can be 

established and controlled from the TDS unit.

 

The facilities connector allows 

access to various switching and output signals and can be used to operate 
remote equipment, generate alarms or give visual indication of status. 

This makes the TDS unit valuable for many applications ranging from:

I

Remote monitoring of audio signals such as transmitter sites.

I

Live monitoring of a sound system.

I

Messaging services.

I

Audio program hookups.

I

Remote switching.
