These devices provide all the functions required to interface a full-duplex (2-wire) voice telephone circuit with a TDM (time-division-multiplexed) system. These devices are pin-for-pin compatible with the National Semiconductor TP3064A and TP3067A, respectively. Primary applications include: Line interface for digital transmission and switching of T1 carrier, PABX, and central office telephone systems Subscriber line concentrators Digital-encryption systems Digital voice-band data-storage……
