Abstract
A time division multiplexing (TDM) method and apparatus for interfacing data channels with a TDM bus. The TDM interface uses a processor and a channel coordinator circuit to indicate which data channels are active, and to assign which TDM transmit channels and which TDM receive channels will correspond to the active data channels. The processor controls the flow of data by using a channel coordinator circuit which controls multiple shift registers. The multiple shift registers control the flow of data between the active channels and the TDM bus. Multiple storage registers are used to buffer the data flowing between the active channels and the shift registers.
