Abstract

A wireless telephone subsystem for coupling line type telephony equipment to the public switched telephone network is described. A base unit is provided which is adapted to be coupled to a plurality of lines of the PSTN. The base unit includes a base coder/decoder which transforms analog signals received from the lines of the PSTN to digital signals and conversely transforms digital signals to analog signals for coupling to the lines of the PSTN. The base unit includes a multiple channel transceiver coupled to the base coder/decoder which responds tothe digital signals provided by the base coder/decoder for transmitting those signals by placing selected portions of the digital signals into selected portions of a multiplex frame. The base multiple channel transceiver also receives digital signals and couples those digital signals to the base coder/decoder Programmable switching means is provided to associate selected of the PSTN lines and selectedportions of the multiplex frame. The subsystem also includes a wireless interface unit for connecting to the line type telephony equipment. The wireless interface unit also includes a remote coder/decoder for transforming analog signals received from the line type telephony equipment into digital signals and for transforming other digital signals into analog signals for coupling to the line type telephony equipment. The wireless interface also includes a remote transceiver which is coupled to the remote coder/decoder. The remote transceiver responds to digital signals from the remote coder/decoder for transmitting the signals into selected portions of the multiplex frame and receives other digital signals and couples those to the remote coder/decoder.
