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 S

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 ter-

minal equipment in which the microphone, loud-

speaker, headset, and handset can be directly

connected to the Analog Front End (AFE).

The AFE and the integrated fixed point DSP per-

form 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.
