(JANAP 128), content indicator code (CIC) (JANAP
128), originating station routing indicator (OSRI),
station serial number (SSN), and time of file (TOF) to
the message. The message is then paged and sectioned
according to JANAP 128, and queued for transmission.
Data-pattern messages may be introduced into the
system via card or magnetic tape. The format will be
in accordance with JANAP 128 procedures for data
messages. During the message preparation, processing,
transmission, and filing, the same controls and
restraints used for narrative message processing will
also apply to data-pattern messages.
The message may also have delivery requirements
for distribution to commands serviced by the
communications center. The system will automatically
assign internal message distribution for all guard
commands. If the system cannot provide internal
distribution, the message will be displayed to the
inrouter for assistance.
MESSAGE AND ROUTING
Most messages have at least one addressee
responsible for taking action on the contents and for
originating any necessary reply. Addressees who have
an official concern in the subject of the message, but
who do not have primary responsibility for acting on it,
receive the message for information. Although
information addressees are usually concerned only
indirectly with a message, they occasionally must take
action of some kind within their own commands. Some
messages contain only information addressees.
Messages may be divided into types, according to
the way they are addressed, as follows:
Single-Address A message that has only one
addressee, which may be either for action or
Multiple-Address A message that has two or
more addressees, which may be either action or
information and where each addressee is informed of
all other recipients.
Book A message destined for two or more
addressees but where the drafter considers it
unnecessary that each addressee be informed of other
addressee(s). Book messages are routed according to
each addressees relay station. All unnessary
addressees are deleted from the face of the message
before being sent to the addressee(s) served by that
particular relay station.
General Message A message that has a wide,
predetermined, standard distribution. General
messages are normally titled with a sequential number
for the current year; for example, ALCOM 28/96,
NAVOP 30/96. The title indicates distribution and
serves as the address designator.
Address groups are four-letter groups assigned to
represent a command, activity, or unit. In military
communications, address groups can be used in the
same manner as call signs to establish and maintain
communications. Generally speaking, the Navy uses
address groups the same way as call signs. Address
groups never start with the letter N; hence, they are
easily distinguishable from naval radio call signs.
Address groups, however, follow no distinctive pattern,
and the arrangement of the four letters that constitute
them conveys no significance whatsoever.
Afloat commands (except individual ships) and
shore-based commands or activities not served by their
own communications facilities are assigned address
groups. For example:
Senior commands and commanders ashore, such
as the Secretary of Defense and the Secretary of
Navy bureaus, systems commands, and district
Elements of the shore establishment having a
need for direct addressing and receipt of message
traffic (such as weather centrals).
Among other uses, address groups facilitate
delivery of message traffic when a communications
center serves so many activities that its own call sign is
insufficient to identify the addressee. Address groups
are contained in Allied Call Sign and Address Group
SystemInstructions and Assignments, ACP 100, and
in U.S. Call Sign &Address Group System Instructions
& Assignments (U.S. Supplement No. 1), ACP 100 U.S.
SUPP-1. Like call signs, address groups are divided
into the following types:
l Individual activity;
l Address indicating; and
