Hagelin CRM-008 Cryptocom
|
 |
|
|
Secure Voice Crypto Unit
The CRM-008 was part of the CRYPTOCOM family of secure voice
units, developed by Crypto AG (Hagelin) in the mid-1970s.
It was intended for civil use (HC-230) as well as for
the military market (HC-235). It was introduced on 1975
and was sold well into the 1990s.
|
The CRM-008 is suitable for direct connection to a telephone line,
but can also be used 'over the air' by connecting it to an HF or VHF
radio.
More information will be presented here as and when it becomes available.
|
|
|
A number of accessories are available for the CRM-008. Some of these
are listed below.
|
When using the CRM-008 over a PSTN telephone line, this special
crypto phone had to be used instead of a standard phone.
The phone shown here is in fact a standard telephone unit that is
modified for crypto use. It has extra switches and and a red light
to show that the connection is secure. The crypto phone has an 8-way
LEMO plug that should be connected to the phone socket of the
CRM-008.

ATF-109 Telephone break-out box
|
|
|
|
In order to connect the CRM-008 to a telephone line, this small
break-out box was used. It has two sets of banana-sockets that are used
to connect to a standard (PSTN) telephone line and (optionally) to a telephone.
A fixed cable with a 10-way LEMO plug is used to connect the break-out
box to the DATA socket of the CRM-008.

ARA-100-001 Radio Interface/Speaker Unit
|
|
|
|
The CRM-008 can also be used over radio. In that case, a radio interface
is used instead of the telephone break-out box. The Radio Interface
has a 10-way LEMO plug that connects to the DATA socket of the CRM-008.
The radio is connected to the rear of this unit, by means of two fixed
wires (which are missing from the unit shown here).

ARA-100-002 Radio Interface
|
|
|
|
This unit is simular the the ARA-100-001 (shown above) but is missing the
internal speaker. Instead it has a socket for headphones.
A fixed cable with a 10-way LEMO plug is used to connect
it to the DATA-socket of the CRM-008.
Furthermore, the radio interface has two short cables for connection to
a military radio set. Both cables have a 13-way military BENDEX plug, one
male, and one female.

|
|
When using the CRM-008 over a radio link, this military-grade
handset should be connected to the phone socket of the CRM-008,
by means of an 8-way LEMO plug (just like the ATF-114 crypto phone).

|
PSM-106 Power Supply Unit
|
|
|
|
|
The CRM-008 can be connected to just any DC power supply with
a voltage between 12 and 30 Volt. The one supplied with the unit
is shown here. At present it is not known exactly how it connected
to the CRM-008, as the DC power cable is missing.
