FOREUORD
* 1.
This mil itary standard [MIL-STD) is approved and mandatory for use
* by all Departments and Agencies of the Department of Defense in
* accordance with DOD Directive (ODDD) 4640.11, dated 21 December 1987.
● 2. Beneficial comments (recommendations, additions, deletions) and
● any pertinent data which may be of use in improving this document
* should be addressed to:
Joint Tactical Command, Control and Commune-
* cations Agency, Washington Office, ATTN: Standards Management and
* Integration Directorate, C3A-ADW-S, 11440 Isaac Newton Square, North,
* Reston, VA 22090-5006, by using the self-addressed Standardization
* Document Improvement Proposal (DD Form 1426) appearing at the end of
* this document, or by letter.
* 3. Original ly, Military Standard 188 (MIL-STD-188) covered tactical
and long haul communications system technical standards, but later
evolved into a document appl icable to tactical communications only
(MIL-STO-188C ).
● 4.
The Defense Comznunications Agency (OCA) published DCA Circulars
promulgating standards and engineering criteria appl icable to the long
haul Oefense Communications System (OCS) and to the technical support
of the National Military Command System (NMCS).
* 5.
As a result of a Joint Chiefs of Staff (JCS) action, standards for
all military communications are now being published in a MIL-STD-188-
100 series covering conaoon standards for tactical and long haul com-
munications, a MIL-STD-188-200 series covering standards for tactical
conanunications only, and a MIL-STD-188-300 series covering standards
for long haul communications only.
Emphasis is being placed on devel-
oping common standards for tactical and long haul communications
published in the MIL-STD-188-100 series.
● 6. This standard contains technical parameters for digital facsimile
equipment used in tactical and long haul communications.
The para-
meters contained herein are consistent with the mandatory parameters
of North Atlantic Treaty Organization (NATO) Standardization Agreement
(STANAG) 5000 and International Telegraph and Telephone Consultative
Committee (CCITT) Group 3 equipment.
* 7.
This document provides mandatory standards for planning, engineering,
procurement and use of digital facsimile equipment capabil ities for 000
communications systems.

MIL-STD-188-161B
SPECIAL CONSIDERATIONS
1.
MIL-STD-188-161B is being issued to make optional certain previously
mandatory requirements which were
necessary for DOD-wide users. This
standard clarifies the requirements and appl ication, allowing’ for tailoring
of requirements to satisfy specific user needs.
Directive (DOOO) 4640.11,
Department of Defense
Mandatory Use of Standards in the MIL-STO-188
Series, mandates the use of standards in the MIL-STD-IBB series.
However,
the directive also requires adherence to the PO1icies in DODD 5000.43,
Acquisition Streamlining.
OOOD 5000.43 states only applicable standards
are to be used and those standards must be tailored in order ,to invoke only
those requirements which are suitable for the user.
2. The following guidance is provided for your use:
a. Unclassified operations: Users that do not need to send
classified information over facsimile equipment,
recommend the CCITT Group
3 analog output machine.
*
b. Classified operations: Users who require the transmittal of
classified information,
recomanend a Type I and/or Type 11 digital output
facsimile machine.
For information,
a dual-mode facsimile machine which
contains Type I and/or Type 11 and CCITT Group 3 protocols will satisfy
unclassified and classified operations.
c. Users must understand that this standard covers the minimum
requirements.
A user must consider the following, prior to purchasing
facsimile equipment:
(1) Interoperabil ity between U.S. and Allied forces, as
required.
(2) Transmission rates required to support all phases of
operational requirements (peacetime through war, tactical , and NATO STANAG
5000).
(3) Multipage requirements.
(4) Forward error correction.
(5) Classified and unclassified processing.
(6) The type of cryptographic equipment being used with the
facsimile equipment.

(7) Resolution requirements (low, medium, and high).
(8) Uncompressed mode requirements (to accommodate noisy
circuits).
(9) Backward compatibil ity
requirements to interoperate
with existing facsimile equipment.
NOTE :
See Sections 1 and 6 for further guidance.
3. For some specific facsimile applications, some or all requirements of
this standard may not be appropriate.
If a waiver to any of the require-
ments is desired,
a request with detailed justification must be forwarded
to the JTC3A (Joint Tactical Command,
Control and Communications Agency),
ATTN : Standards Management and Integration Directorate, C3A-ADW-S, 11440
Isaac Newton Square, North, Reston, VA 22090-5006 for inter-OOD component
systems and equipment, and to the head of the 000 component for intra-OOD
component systems and equipment, providing a copy to the JTC3A.
