CM 115 E

VOICE/DATA ENCRYPTION
EQUIPMENT

The CM115E equipment is a digital
ciphering device that can be config­ured for voice or data applications.It
can be used in conjunction with HF,
VHF and UHF radios providing ei­ther narrow or wide band channels.

The voice analogue signal is internal­ly converted to a digital signal, en­crypted through a high-grade securi­ty algorithm, modulated and sent to
the external radios for transmission.

The crypto algorithm is a propri­etary Marconi Selenia Communica­tions algorithm that can be cus­tomised by the end user.

Plain mode is also available. The op­erator can select the working mode
as well as the key variable. Rapid
erasure of all keys is possible.

The equipment can store up to 60 ke y
variables. Key loading is performed by
means of portable electronic transfer
devices (Tape Reader,Fill Gun,etc.)

The CM115E can be provided with

the following Ancillary Units:

• CP1144/D,Remote Control Unit

• MT1133/D,mounting slide
The equipment operates in the fol-

lowing modes:

Narrow Band

Voice Mode:

• Headphone interface (Voice in/out
(0 dBm/600 Ohm),PTT)

• Analogue-to-Digital Voice conver­sion (LPC10 Vocoder at 2400 bps)

• Digital Encryption

• Analogue modulation (Modem set
in voice mode)

• Radio interface

Data Mode:

• DTE interface (electrical interface
V.10)

• Synchronous encryption and trans­mission at 300,600,1200,2400 bps

• Analogue modulation (Modem set
in data mode)

• Radio interface

Wide Band

Voice Mode:

• Headphone interface (Voice in/out
(0 dBm/600 Ohm),PTT)

• Analogue-to-Digital Voice conver­sion (CVSDM 16 kbps)

• Digital Encryption

• Radio interface (BB / Diphase
modulation)

Data Mode:

• DTE interface (electrical interface
V.10)

• Synchronous encryption and trans­mission at 8 or 16 kbps)

• Half-duplex/Full-duplex Transmis­sion Mode

The CM115E also incorporates the
following features:

• CIK (Crypto Ignition Key)

• Anti-tampering mechanisms

• Battery for key holding

• Crypto alarms

• Local (Keyboard & Display) and
remote control (RCU)

• BITE

The chassis is a lightweight alumini­um alloy casting composed of three
sub-assemblies:

• Front panel

• Main chassis

• Rear panel

The equipment is based on modular
assembly allowing easy module sub­stitution and maintenance.
