MIL-STD-188-185 Interoperability Standard For Uhf Misaltcom Dama Control SystemThis standard establishes mandatory requirements applicable to the channel controller \(CC\) to provide the capability for terminals to access pre-assigned \(PA\) or demand-assigned \(DA\) user-to-user communications \(UCOM\) services that operate on either 5-kHz or 25-kHz ultra high frequency \(UHF\) satellite communications \(SATCOM\) channels and represent the minimum requirements that must be implemented. Requirements in this standard may be exceeded by the CC to satisfy specific Department of Defense \(DoD\) requirements, provided interoperability is maintained. For example, the incorporation of additional standard and nonstandard interfaces is not precluded. MIL-STD-188-181 defines the modulation types and rates, forward error correction \(FEC\), interleaving, user-traffic communications security \(COMSEC\), and performance parameters that apply to the bursts employed for each transmission employed in this standard.

MIL-STD-188-185A

FOREWORD

1. This standard is approved for use by all Departments and

Agencies of the Department of Defense (DoD).

2. In accordance with DoD Instruction 4630.8, it is DoD policy

that all joint and combined operations be supported by compatible,

interoperable, and integrated command, control, communications,

and intelligence (C3I) systems. All C3I systems developed for use

by U.S. forces are considered for joint use. The Director,

Defense Information Systems Agency (DISA) serves as the DoD single

point of contact for developing information technology standards

to achieve interoperability and compatibility. All C3I systems

and equipment will conform to technical and procedural standards

for compatibility and interoperability.

3. Military Standards (MIL-STD) in the 188 series (MIL-STD-188-

XXX) address telecommunications design parameters and are to be

used in all new DoD systems and equipment, or major modifications

thereto. The MIL-STD-188 series is subdivided into a MIL-STD-188-

100 series, covering common standards for tactical and long-haul

communications; a MIL-STD-188-200 series, covering standards for

tactical communications; and a MIL-STD-188-300 series, covering

standards for long-haul communications. Emphasis is being placed

on the development of common standards for tactical and long-haul

communications (MIL-STD-188-100 series). The MIL-STD-188 series

may be based on, or may make reference to, American National

Standards Institute (ANSI) standards, International

Telecommunications Union - Telecommunication Standardization

Sector (ITU-T) recommendations, International Organization for

Standardization (ISO) standards, North Atlantic Treaty

Organization (NATO) standardization agreements (STANAG), and other

standards, wherever applicable.

4. This standard complies with Joint Staff direction requiring

that a new standard be developed to define all technical

characteristics essential for interoperability and performance of

satellite communications (SATCOM) terminals that use 5-kilohertz

(kHz) and 25-kHz ultra high frequency (UHF) SATCOM channels. This

standard defines mandatory system parameters for planning,

engineering, procuring, and using UHF SATCOM channel controllers.
