Telephone Dialup System TDS1 S/R with original installation and operating handbook.
What is a Telephone Dialup System? Quite simply it is a device for sending sound (audio) down a normal telephone line, similar to a radio station “phone in”. You can simply dial a number on your telephone or mobile from anywhere in the world, and listen in, live, to a sound system. This could be your church, interview suite, kingdom hall, conference centre or ……. anywhere that has a Dialup fitted…… more. For best results, listen via a loudspeaking telephone with volume and tone controls.What are they used for? The Telephone Dialup System (TDS) is simply the interface between the telephone network and a sound system. Examples are: Listening to the local meeting hall or church live at home, live translation service, Monitoring a remote interview location, Relaying a conference to an overflow location, Single touch recordings, Remote announcement over PA, Covert recording, Remote monitoring of landlines, Auto answering a premium rate line with a pre-recorded message etc…make money
How does it work? The Dialup unit is fitted at the sound sending end and connects to both a standard telephone line and the sound source. It can then be used in one of two ways: 1) To automatically answer anyone calling in and connect them to the sound or 2) In manual mode the call is controlled by the sending end…. more.
Where do I start? First you need to decide what your need is – single (TDS1), single with answer (TDS1SR), or double (TDS2) line unit or a combination of units. Then you need a telephone line installed at the sound source for each listener though note these can be shared with other equipment such as a Fax, telephone, alarm etc. Finally, you need a signal from the sound system….more.
What’s different between the new and old versions? Whilst the function of the Dialup unit remains much the same, it has been radically upgraded and has included virtually all the requests and suggestions from existing users. Major changes are:
