| Summary: | The MT8992-Digital Phone(D-Phone) and MT8930-Subscriber Network Interface Circuit(SNIC) devices are presented in this project developement. The D-Phone is a fully integrated digital telephone IC designed for used in a Terminal Equipment. It incorporates an on-chip Codec, a tone ringer, a DTMF generator, speaker-phone algonthm, an interface to Standard telephony transducers and HDLC Transceiver which transmit and receive the packetized data (information or control) serially in a frame format.The SNIC is a device which implements the CCITT 1.430 recomendation for the ISDN S Reference Points. Providing point-to-point digital transmission, the SNIC may be used at either end of the subscriber line (NT or TE). The two devices can be controlled by a microprocessor or ST-Bus(serial Bus) for interfacing. |
