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 - 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.

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"
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"
