MIL-STD-188-110 Interoperability And Performance Standards For Data ModemsThis document establishes mandatory technical standards and design objectives \(DO\) that are necessary to ensure interoperability and to promote performance among data modulators-demodulators \(modems\) used in the voice frequency \(VF\) band of long-haul and tactical communications systems. This document also provides guidance to the designers of new data modems that incorporate characteristics not yet standardized by specifying the technical characteristics of data modems currently in the inventory. The purpose of this guidance is to ensure attainment of minimum acceptable performance and maximum interoperability between existing and future data modems with specified transmission channel conditions.

FOREWORD

1. This Military Standard is approved and mandatory for use by all Departments and Agencies

of the Department of Defense (DoD) in accordance with Joint Technical Architecture (JTA)

Version 6, dated 3 October 2003.

2. This document contains technical standards and design objectives for minimum interface and

performance standards pertinent to voice frequency band modulators-demodulators (modems)

which operate in both long-haul and tactical communications systems. The terms "system

standard" and "design objective (DO)" are defined in FED-STD-1037. In this document, the

word "shall" identifies mandatory system standards. The word "should" identifies Dτs that are

desirable but not mandatory.
