Marconi Selenia Crm115e Voice Data Encryption Equipment Manual

							CM 115 E
VOICE/DATA ENCRYPTION
EQUIPMENT 
						

							The CM115E equipment is a digital
ciphering device that can be config-
ured for voice or data applications.It
can be used in conjunction with HF,
VHF and UHF radios providing ei-
ther narrow or wide band channels.
The voice analogue signal is internal-
ly converted to a digital signal,en-
crypted through a high-grade securi-
ty algorithm,modulated and sent to
the external radios for transmission.
The crypto algorithm is a propri-
etary Marconi Selenia Communica-
tions algorithm that can be cus-
tomised by the end user.
Plain mode is also available.The op-
erator 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 key
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

¥Analogue modulation (Modem set
in voice mode)
¥Radio interface
Data Mode:
¥DTE interface (electrical interface

sion (CVSDM 16 kbps)¥Digital Encryption
¥Radio interface (BB / Diphase
modulation)
Data Mode:
¥DTE interface (electrical interface
V.10)
¥Synchronous encryption and trans-
mission at 8 or 16 kbps) 
¥Half-duplex/Full-duplex Transmis-
sion 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 alumini-
um alloy casting composed of three
sub-assemblies:
¥Front panel
¥Main chassis
¥Rear panel 
The equipment is based on modular
assembly allowing easy module sub-
stitution and maintenance.
