Telephone Supervisory Adapter
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.
TSA-3LM is supplied with cables and connectors which have been wired
for use with Total Recall recorders from Omnicron. It can be
customized to meet unusual requirements. Consult your place of
purchase if cables are required with non-standard lengths,
connections, or circuitry. On the back of this instruction sheet is
a drawing that shows a typical installation.
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
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.
IN CASE OF DIFFICULTY If
the recorder fails to record properly, recheck all connections and
test your recorder to see that it is operating properly. Make sure
that the microphone is only active when off-hook, otherwise you
could record room sounds between conversations (set phone jumpers,
or program it for switched transmit audio). Assistance is available
from your place of purchase, or directly from Omnicron Electronics
at the phone numbers listed below and via this web site listed
law 90-351 title 18, section 2511, sub section 2D, requires that at
least one participant in a recorded conversation be informed of the
recording. Check your state and local regulations for further
assistance in the selection of the products that are best suited to your application.|
