TSA3LM Telephone Supervisory Adapter
The TSA-3LM is used to provide a simple method of connecting supervisory
monitoring equipment to the handset circuit of a telephone. It is usable on most
telephone styles that have a standard modular handset or headset jack.
Installation
The TSA-3LM is supplied with cables and connectors which have been wired for use
with Total Recall recorders. It can be customized to meet unusual requirements.
If your recorder is more than twenty-five feet from your phone, extension cables, such
as the T25-EXT, are available. The cable between the TSA-3LM and your recorder
may also be extended in other ways. Only the center two wires in the output cable
(red & green) are used to feed telephone audio to your recorder.
1. Unplug the handset cord from your telephone set and plug it into one of the two
jacks on the TSA-3LM adapter.
2. Using the short cable which was supplied with the TSA-3LM, plug one end of the
cable into the handset jack on your phone and the other end of the cable into the
remaining jack on the TSA-3LM. Your telephone should now function normally as you
have simply connected a short extension into the handset cord.
3. The TSA-3LM can now be connected to your supervisory equipment (voice logging
recorder, monitor amplifier, etc.). Normally the center two wires on the handset jack
are the earpiece circuit. The TSA-3LM has a twenty-five foot cable which connects to
this circuit. It can be used to feed audio to the LINE or AUXILIARY (AUX) input of your
recorder so that both sides of all conversations on the handset can be monitored. If
your telephone does not use standard connections, the plug may have to be re-wired
so that the recorder is connected to the correct wires.
If your monitoring equipment interferes with the operation of your phone in any way,
or if your monitoring equipment is not designed to be connected to your telephone in
this manner, a different means of interconnection may be required.
4. Locate a convenient spot on your phone to mount the TSA-3LM. Insure that there is
enough slack in the cables so that they can be easily un-plugged, if required, and
that it will not interfere with the operation of the phone. Use the double stick foam
tape and cable ties that are included with each TSA-3LM to attach it to your phone
and secure the cables.
