COMMUNICATIONS TIMING AND SYNCHRONIZATION SUBSYSTEMS

Organization:

DOD - DC - Defense Information Systems Agency (DISA), (DepSO)

Year: 1991

Abstract: This handbook has been prepared to assist engineers and staff planners in understanding military communications timing and synchronization subsystems. It is designed to enhance the understanding of the parameters and characteristics found in the timing and synchronization needs of the military communications environment.
This handbook is designed to be used in the planning and implementation of timing and synchronization for Department of Defense digital communications systems. It applies to federal-government-owned-and-operated digital communications systems and does not necessarily apply to leased commercial facilities.
The objective of this handbook is to provide general technical information pertaining to communications timing and synchronization subsystems. It is to be used with MIL-STD-188-115, Interoperability and Performance Standards for Communications Timing and Synchronization Subsystems.
