The INCA-P, PSB 21493, integrates in a single clip,

all the functions required for a high feature PBX

phone.

The line transceiver of the INCA-P implements the

subscriber access functions for a digital PBX ter-

minal to be connected to a two-wire U

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-P 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 fixpoint DSP perform

signal processing tasks such as encoding,

decoding, filtering functions, and tone generation

(ringing, audible feedback tones, and DTMF sig-

nal). A full-duplex echo cancellation mechanism

provides high quality speakerphone functionality.
