Carrier Operated Relay/ Carrier Operated Squelch - A receiver
signal that gives a positive indication a carrier or signal is being
received and the receiver is unsquelched.
Control Processor Module - This ACU module controls all aspects of
system operation.
Dual Tone Multi Frequency - The standard touch-tone telephone
dialing method sends DTMF characters over the Public Switch
Telephone Network (PSTN) line.
Digital Signal Processing (or Processor).
The Digital Signal Processor Module, the main radio interface of the
ACU-1000 system. DSP algorithms provide Voice Operated
Transmit (VOX), Voice Modulation Recognition (VMR), Audio Delay,
Noise Reduction, and Tone Keying functions.
Each interface module in the ACU-1000 system is given an
extension number. A user enters this extension number to make a
communications link through the selected module.

Squelch
A means of detecting audio and causing some action when it is present,
such as keying a transmitter or unmuting an audio path.
TX
Transmit or Transmitter.
VMR
Voice Modulation Recognition. A type of squelch, which is activated only
by spoken words and not by tones, noise, or other audio information.
VOX
Voice Operated Xmit (Transmit). A circuit or algorithm, which causes a
transmitter to key or some other action when voice is present.
This squelch type is activated by any audio signal, and is not restricted to
voice only.

Creating & Breaking Patches
Keyboard Operations


Making and breaking connections with the keyboard consists of the
same operations that would be used with the mouse, except each
mouse click has a corresponding keystroke series: The “##” symbol
represents a two-digit module and the # represents the one-digit net
number in each command.
 Click on module icon (left-click or Connect):
c##
 Right-click (Disconnect) on module icon:
d##
 Click on net number icon (Vertical Connection):
n#
 Right-click on net number icon (Break VC.):
b#
 Click on column heading (enter/exit Monitor Mode):

Creating & Breaking Patches
Connection Types
 Five types of connections
 Normal - form new nets
 Vertical - join existing nets together
 Priority - temporarily patch members of existing nets
together, removing them from their original nets for the
time being
 Permanent – add protection to existing nets
 Monitor – one-way connection – listen, but not speak
OEC/ICTAP

22
Creating & Breaking Patches
Normal Connections

Each connection takes two left clicks of the mouse to make or one right click to
break
 Create a net – left click on one idle module then left click on another one, to
create additional nets - repeat step
 To add more than two modules to net left click on the desired idle module
then left click on the net number or one of the module already on the net
 To break a module from a net right click the module to break an entire net
right click the net number

Creating & Breaking Patches
Priority Connection
NOTE: This is to temporarily patch active members of existing
nets together, temporarily removing them from their original nets
 To join – left click on one active module in a net then left click on
the desired module in a different net
 To disconnect - right click on the red number in the module icon

Creating & Breaking Patches
Permanent Connection

Adds protection to nets so you can not accidentally disconnect the
modules in them - Permanent Connection.
 To create – Make normal net as shown on the normal connection
slide. Next on the dropdown tool bar select PermConn. Select the
net number you want to make permanent. The letters “PC” appear
in the connected modules.
 To remove – PermConn is a toggle switch. On the dropdown tool
bar select PermConn then select the net number you no longer
want protected the letters “PC” disappear. The net can now be
deleted in the normal fashion.

Connection
 The M in the module’s icon shows who is doing the
monitoring and the numbers below shows which modules
are being monitored
 To remove monitor - enter monitor mode by left clicking on
