initiate, extend, preempt, and release calls using
the four-by-four key sender and other functional
pushbuttons. Any connection can be broken
down manually, through operator intervention
and action, or automatically, through a
subscriber going to an on-hook condition. Up to
18 terminals may be connected as either 4-wire
DTMF signaling trunks, or DC closure dial
pulse or DTMF trunks, E&M dial pulse or

• PQS Question 103.3 Discuss the general
use of the Tactical Data Network (TDN)
Tactical Data Network
The TDN system consists of a network of
gateways and servers interconnected with
one another and their subscribers via a
combination of common user, long-haul
transmission systems, along with local area
networks (LANs) and switched telephone
systems.
Tactical Data Network
TDN provides its subscribers with basic data
transfer and switching services; access to strategic,
supporting establishment, joint, and other-service
component tactical data networks; network
management capabilities; and, value-added services,
such as message handling, directory services, file
sharing, and terminal emulation support. It will
provide Internet Protocol connectivity for tactical
data systems and the DMS.

PQS Question 103.4 Discuss the tactical
employment and purpose of NMCB
communication systems
Communications System
The primary purpose of communications is to
facilitate command and control. In this role,
communications is the instrument by which a
commander makes his will known and provides
the “voice of command.”
A secondary purpose of communications is to
facilitate the transfer of information between
individual elements in order to coordinate their
actions to accomplish assigned missions.

• PQS Question 103.6 Discuss the
following communication and information
systems planning factors
a. Mission
b. Available resources
c. Environmental
Communications Planning
Communications control begins with
planning for an operation/exercise and
continues throughout the deployment,
installation, maintenance, and
redeployment phases.
Planning Phase
The Planning phase consists of both operational
and technical planning. It culminates in the
issue of a command element OPORD and a
supporting communications unit OPORD.
This phase is characterized by extensive
coordination meetings between the supporting
communications unit(s) and supported staff.
Deployment Phase
• During this phase, OPCON of the communications units and/or
detachments is transferred to the supported CE Command
Element.
• The CIS plan is refined through coordination among the
supporting communications unit(s) and the supported G-6/S-6
staffs and key staff officers (e.g., the G-2/S-2 for intelligence
CIS requirements, the fire support coordinator for fires CIS
requirements, etc.).
• Limited execution is performed during this phase, including
tracking message traffic and operating in-transit radio circuits,
as required.
Mission
The mission statement describes, in concise terms,
the location of the operation, the time it will
occur, and the tasks to be accomplished.
The mission includes the commander’s intent—the
purpose of the action.
Careful review of the mission gives the CISO a
general idea of what overall CIS resources will
be required to support the operation.
Available Resources
• The CISO must consider all available resources to
determine the extent of support that can be provided
and to determine shortfalls in the capability to
support the mission. This includes resources both
organic and external to the MAGTF.
