SIGINT is a contraction of SIGnal
INTelligence, It is one of the major
forms of intelligence.Signals intelligence
satellites are designed to detect
transmissions from broadcast communications
systems such as radios, as well as
radars and other electronic systems.The
Interception of such transmissions
can provide information on the type
and location of even low power transmitters,
such as hand-held radios.However,
these satellites are not capable
of intercepting communications carried
over land lines, such as under-sea
fiber optic cables.

Secure Telephone is a communications system
the need for the protection of vital and sensitive
information over a telephone system. Secure
Telephone is a compact, self- contained, desktop
of providing the user with both clear as well
as secure voice and data transmissions. It's
uniqueness lies in the fact that it works as
an ordinary telephone simultaneously providing
a secure telephone network to the other terminals.
Interception, Monitoring and Logging Infrastructure
(COMINT) involving the covert interception
of foreign communications
has been practiced by almost every advanced
nation since international telecommunications
became available. COMINT is a large-scale industrial
activity providing consumers with intelligence
on diplomatic, economic and scientific developments.

presented many problems directly related
to compatibility, especially with the
development of digital radio technology.
In 1982, The
GSM group ("Groupe Spécial Mobile" (French)
was formed to address these problems.
