This manual contains the combined service and maintenance instructions necessary for servicing and maintaining

the AN/GSC-24(V) multiplexer set in an operationally ready condition. The multiplexer set is a versatile asynchronous

time-division multiplexer that can be configured for simplex or full-duplex operation. Up to 15 channels of voice data, high-

speed and low-speed digital data with timing, and/or selected low-speed digital data without timing can be multiplexed and

demultiplexed in the multiplexer set. The technical capabilities of the multiplexer set are listed in chapter 1.

This manual is divided into six chapters. Chapter 1 contains descriptive information, operating parameters, and
