- A. Before You Begin
- There are (2) versions of CPS that may apply to the RT-5000 depending upon P/N as follows:
- 9. Conventional - All the aspects of any given channel are assigned to a personality numbered 1 through 255. These menus allow the user to modify the settings for the Conventional Personalities.

Operator’s Manual
1. Applicability
This manual describes how to configure and use Cobham C-5000 Communication Management
Controllers with part numbers in the 31300-1X02-XXXX series (where X can be any digit), and the civil
support software configuration. Although this manual is largely applicable to previous software versions,
some recently added features may not be available, and minor operational changes in previously
available features may exist.

Glossary
AM – Acronym for “Amplitude Modulation”. In this type of modulation, the amplitude of the signal is varied
in proportion to the voice or data input signal. The signal quality can be severely degraded because of
lightning or man made electrical noise. AM is only used in the frequency ranges 108 to 152 MHz and 225
to 400 MHz. All air traffic control functions use AM modulation.
Audio Phase – The RT-5000 can invert the phase of the audio signal during transmit or receive. This is
sometimes necessary for DPL systems to work.
Bandwidth – A term used to describe the amount of frequency a channel has to transmit a signal. Two of
the most common FM channel bandwidths are 12.5 kHz (Narrow) and 25 kHz (Standard). Some special
signals, such as military encryption, work best when using 35 kHz (Wide) or 70 kHz (Extra-wide)
channels. All of these bandwidths are available in the RT-5000.
Channel – A group of radio characteristics, such as RX & TX frequencies, modulation, power levels, etc.
CMC – An acronym for Communication Management Controller. The C-5000 is a CMC.
CTCSS – Acronym for “Continuous Coded Squelch System”.
DCS – Acronym for “Digital Coded Squelch”
DES – Acronym for “Digital Encryption Standard”. This is an algorithm by which signals are encrypted.
Deviation – The amount of peak change the RF signal varies from the carrier in proportion to the
amplitude of the voice signal.
DPL – Acronym for “Digital Private Line”. Also known as DCS.
DTMF – Dual Tone Multiple Frequency. On a telephone keypad, each row and column have unique audio
tones that are sent when a button is pushed. At the receiver, a decoder listens for a row tone and a
column tone and can determine from that, which button has been pushed.
Direct – Also known as simplex, car-to-car, and talk-around. This mode of operation allows you to bypass
the repeater and talk directly to another radio. TX and RX frequencies are the same.
Encryption – Method by which a signal is “scrambled” so that other listeners without the proper
encryption key cannot understand what is being transmitted.
Encryption Key – When encrypting a transmission, the algorithm used to scramble the information
requires both the transmitting and receiving devices to have a number. This number is called an
Encryption Key. Some systems are limited to one key and others are capable of having multiple keys.
