The INCA-S, PSB 21483, integrates in a single chip all the functions required for a full- featured ISDN phone. The line transceiver of the INCA-S implements the subscriber access functions needed for an ISDN or PBX digital terminal connected to a four-wire S0 Interface. The chip provides complete Layer-1 and basic Layer-2 functions for digital terminals. Different interfaces allow connection to a variety of devices including a full-speed USB interface for PC host communications. The INCA-S is typically used in applications for terminal equipment in which the microphone, loudspeaker, headset, and handset can be directly connected to the Analog Front End AFE . The AFE and the integrated fixed point DSP perform signal processing tasks such as encoding, decoding, filtering, and tone generation ringing, audible feedback tones, and DTMF signal . A full duplex echo cancellation mechanism provides high quality speakerphone functionality.
