TELECOMMUNICATIONS PULSE-COOE MODULATION TELEMETRY UNIFIED S-BAND NAL CONDITIONER TRIPLEXER VHF/AM 0 FREQUENCY SWITCH P DATA LINK S-BAND POWER AMPLIFIER P-223 Location of main TELECOMMUNICATIONS equipment The TELECOMMUNICATIONS subsystem provides voice, television, telemetry, and tracking and ranging com munications between the spacecraft and earth, be tween the CM and LM, and between the spacecraft and astronauts wearing the portable life support system. It also provides communications among the astronauts in the spacecraft and includes the central timing equipment for synchronization of other equipment and correlation of telemetry equipment. For convenience, the TELECOMMUNICATIONS sub system can be divided into four areas: intercom munications (voice), data, radio frequency equip ment, and antennas. Most of the components of the TELECOMMUNICATIONS subsystem are produced by the Collins Radio Co.
