- TDM with direct wiring on the RJ21 plug
Identify the wire-pair(s) that carries the signal and hook these to the recording channels on the RJ21
plug by soldering or whatever means you prefer. Note that the 4-wire connection must be on adjacent
recording channels (f.i. CH1+CH2, NOT CH2+CH3)
- TDM with the RJ11 patch box
Use a RJ45 'T'-splitter and make a
custom (DIY) cable to adapt for the
various PBX manufacturers.
You need to make a custom cable for
every telephone to tap.
The custom cables are built with
standard modular cable.
One end has a RJ11 (6P4C) modular
jack and the other end has a RJ45
(8P8C) attached. There are different
wiring schemes to follow for the various
PBX brands.
Always test ONE custom cable first to
avoid time and material loss.
