It has a control unit, radio cabinets, antennas, a power plant, and data terminals. MTSO- The switching ofce, the central coordinating element for all cell sites, contains the cellular processor and cellular switch. It interfaces with telephone company zone ofces, controls call processing, provides operation and maintenance, and handles billing activities. There are two basic cellular systems; one is the circuit-switched system and the other is the packet-switched system. In a circuit-switched system, each trafc channel is dedicated to a user until its cell isterminated. We can further distinguish two circuit-switched systems: one for an analog system and one for a digital system. A basic digital system consists of four elements: mobile station, base transceiver station BTS , base station controller BSC , and switching subsystems.
