system bus 78 along with a program rom 80 and static ram 82 ram 82 is used for storing information for various purposes such as storing program variables mailbox information and stack parameters a burst mode controller bmc 84 for creating the slots for transmission at precise times is also connected to system bus 78 and consists of a number of components a bmc bus 85 is connected to system bus 78 via a bmc bus controller 86 whose general function would be understood by those skilled in the art an adaptive differential pulse code modulation adpcm voice coder 88 provides encoding and decoding of audio information a digital signal processor 89 interacts with voice coder 88 and an interface unit 90 to generate the audio information bits to be transmitted a microphone and speaker 91 in the telephone handset are connected to interface unit 90 in the base station interface unit 90 is connected to the land line network connection a slot opcode data ram 92 contains certain protocol bits address bits and data bits which will be called upon during operation of the tdma controller to build a slot for transmission or to store a received slot an address generation unit agu 93 addresses the information in ram 92 under the control of a sequencer 94 sequencer 94 which will be described in greater detail later is the device that controls assembling the slots for transmission and disassembling the slots after reception at synchronized times by outputting control flow sequences to the modem interface unit 95 modem interface unit 95 receives control.
