Lesson 1/Learning Event 10
Learning Event 10: COMMUNICATIONS CONTROL.
Every communications system, regardless of size or complexity, must
have centralized control.
Lacking such control, the maze of comminations
channels that make-up a modern communications system become hopelessly
entangled. Under proper supervision, direction and control, these circuits
are made to serve all users of the DCS System.
a. Technical control centers are located at each end of a multichannel
system. Facilities are provided for operators or technician to communicate
with each other.
Using the order wire channel, they coordinate their
activities to achieve maximum use of available facilities.
b. The technical controller must have a thorough knowledge of the
varied types of communications systems and equipment in use today.
The
technical controllers at the different facilities must work together as a
team
to
provide
communications
that
meet
or
exceed
the
Defense
Communications Agency (DCA) standards.
Learning Event 11: CATEGORIES OF DCS SERVICE.
a. Many types of communication services are provided by the Defense
Communications System (DCS) under control and supervision of DCA.
To aid
DCA in establishing control and supervision, DCA publishes a DCS Technical
Schedule to provide a common language for DCS circuit ordering, allocation,
activation, operation and maintenance. They serve two primary purposes:
(1) Service description tables.
Provides a guide for the circuit
engineer to identify standard circuit performance parameters used to support
a particular service.
(2) Circuit parameter tables. Provides the allocator/engineer with a
shorthand method of specifying quality control circuit parameters in the
Telecommunication Service Order (TSO) without providing details of the
required performance.
b. The technical schedule includes a brief description of the type of
service to be provided along with the circuit parameter code.
c. User-To-User circuits.
Is a circuit of any organization, unit,
office or individual that has equipment connected to a DCS circuit and uses
the DCS for communications.
Basically it is a term used to identify two
user terminals directly connected through the DCS.
