Definitions
“66” Punchdown Terminal Block:
A connection peripheral used to interface telephone lines easily.
Analog Communication:
The type of communication in which a standard residential type phone may be used. The
SO-24A
can monitor any analog communication path that is compatible with standard analog telecom equipment.
Dial Up Code:
The 2, 3 or 4 digit Touch Tone code dialed from the observing phone to listen to a specific analog
station or line.
Digital Communication:
The type of communication used on digital phone systems in which proprietary phones
must be used. The
SO-24A
can monitor certain digital systems. This requires the
SO-24 AK
and a dedicated pair
of wires between each phone and the
SO-24A
. The audio must be taken from the digital phone’s receiver (earpiece)
for each of the stations to be observed, following the wiring table shown in
Wiring
section
A
.
Note:
When using the
“Talk Assist” feature with the
SO-24 AK
, the outside party will not hear the supervisor, ONLY the inside agent will hear
the supervisor. For more information on Digital System Interfaces, see DOD# 819.
Master Module:
The primary
SO-24A
module in a multi-unit configuration (DIP switch 1 ON) or the only module in a
single-module system.
Slave Module(s):
Any module(s) in addition to the Master module, used to increase capacity (DIP switch 1 OFF).
Installation
A
SO-24A
system consists of at least one Master
SO-24A
module, and as many as nine (9) Slave modules. Multiple
SO-24A
modules are interconnected from module to module, using the supplied modular cords, daisy-chaining the
modules from
INPUT
to
OUTPUT
. If more than one
SO-24A
module is being installed, it will be necessary to set DIP
switch 1 to OFF on each slave module. The observing phone and optional tape recorder must be connected to the
Master module.
