GENERAL DESCRIPTION

The Am79C30A Digital Subscriber Controller (DSC) Circuit and Am79C32A ISDN Data Controller (IDC) Circuit, shown in the Block Diagram, allow the realization of highly-integrated Terminal Equipment for the ISDN. The Am79C30A/32A is fully compatible with the CCITT-I-series recommendations for the S and T reference points, ensuring that the user of the device may design TEs which conform to the international standards.

DISTINCTIVE CHARACTERISTICS

■ Combines CCITT I.430 S/T-Interface Transceiver, D-Channel LAPD Processor, Audio

■ Processor (DSC device only), and IOM-2 Interface in a single chip

■ Special operating modes allow realization of CCITT I.430 power-compliant terminal equipment

■ S- or T-Interface Transceiver

— Level 1 Physical Layer Controller

— Supports point-to-point, short and extended passive bus configurations

— Provides multiframe support

■ Certified protocol software support available

■ CMOS technology, TTL compatible

■ D-channel processing capability

— Flag generation/detection

— CRC generation/checking

— Zero insertion/deletion

— Four 2-byte address detectors

— 32-byte receive and 16-byte transmit FIFOs

■ Audio processing capability (DSC circuit only)

— Registers for implementation of software-based speaker phone algorithms

— Dual audio inputs

— Earpiece and loudspeaker drivers

— Codec/filter with A/μ selection

— Programmable gain and equalization filters

— Programmable sidetone level

— Programmable DTMF, single tone, progress tone, and ringer tone generation

— Programmable on-chip microphone amplifier

■ Pin and software compatible with the Am79C32A ISDN Data Controller (IDC?) Circuit. The Am79C32A is used in data-only applications.
