Total Recall Installation/Wiring Overview
The Total Recall line interface is a two-wire analog. The connector terminations on the rear panel of
the recorder are standard RJ11C/RJ12/RJ14 (6P6C) sockets. The line interface on the recorder is a
terminating point and not a pass through point, therefore, it is not possible to connect the recorder in
series with a telephone handset. The line interface connection from the recorder must be run back to
a termination point. This termination point is normally a parallel tap to tan extension line, a trunk line
or a handset on an analog or digital telephone, depending the application.
Most PBX installations have an MDF or distribution frame fitted between the incoming trunk lines and
the premise equipment. The trunk lines are terminated to the MDF, and then connected through to the
PBX. Similarly there is normally a distribution frame on the extension (office) side of the PBX. From
this frame the telephone cabling is routed through the office/work area to individual telephones or
telephone connection points.
The recorder can be located near the PBX and distribution frame or near the designated user(s) in the
office area.
Connecting to Analog Trunk or Analog Extension Lines
Total Recall can be connected to the trunk side or the extension side of the PBX, depending on user
preferences and operational requirements. The main difference is that an extension side connection
will enable the recording of internal (extension to extension) calls. In this case, the extension number
dialed may be recorded as a search field, provided the handset generates a DTMF dialing tone.
If the number of extensions exceeds the number of trunks, and the requirement is only to record
external calls and not internal office calls, then the recorder can be connected to the MDF or
distribution frame on the trunk side. Connecting on the trunk side will permit Caller-ID capture if
Caller-ID is activated.

2 Wire Analog Direct to Trunk Lines - in the example below Total Recall is patched directly to analog trunk
lines (standard POTS circuits). All call activity, incoming and outgoing will be recorded. The Recorder can be
located in the PBX Room or in the "front office"
lines (standard POTS circuits). All call activity, incoming and outgoing will be recorded. The Recorder can be
located in the PBX Room or in the "front office"
2 Wire Analog - in this example the recorder is patched onto an analog distribution strip within the
communications PBX room. Only three of the five extensions will be recorded. If required, the recorder can be
located out in the office area and wired back to the distribution frame.

Connecting to a Digital Phone using Telephone Adapters/Logger Patches
Many PBX extension installations are digital. It is common to have digital signaling on the extension side, with
analog or digital trunk lines installed. It is important to know the configuration of your PBX system before
installing the recorder.
Total Recall will not record a digital line signal directly into the recorder, so digital to analog conversion must
be done prior to connection to the recorder. You can use the D/A converter that is built into digital phones by
taping the analog audio at the handset/headset connection with a handset adapter. The D/A converter is not
provided with Total Recall, a third party product would be required for this function.
Most digital PBXs generate their own signaling protocol, recording from digital lines or handsets can be
different for each application. Most digital handsets have audio signaling in the handset, with the speaker
(earpiece) and microphone (mouthpiece) channels being connected to the recorder. A "Handset Adapter" can
be used to parallel tap the audio inputs on the recorder. It is possible to find a signal level difference between
the speaker and microphone, and therefore, in a recorded conversation, one party may be heard more clearly
than the other. This is a limitation of recording via handset adapters, not a recorder limitation.
The diagram below shows a "representation" of how handset adapters may be used to enable recording direct
from digital handsets.
