The SCOUT-S or SCOUT-SX respectively integrates all necessary functions for the
completion of a cost effective ISDN voice terminal solution.
Please note: Throughout the whole document “SCOUT
The SCOUT combines the functionality of the ARCOFI
Codec Filter Basic Function) or ARCOFI
Speakerphone) respectively and the ISAC
Controller for Terminals) on a single chip.
The SCOUT-S is suited for the use in basic ISDN voice terminals just as it is, and in
combination with an additional device on the modular IOM
featurephones e.g. with acoustic echo cancellation.
The SCOUT-SX PSB 21383 is an extended SCOUT-S PSB 21381 which provides the
speakerphone performance of the ARCOFI-SP PSB 2163.
The transceiver implements the subscriber access functions for an ISDN terminal to be
connected to a four wire S/T interface. It covers complete layer-1 and basic layer-2
functions for digital terminals.
The codec performs encoding, decoding, filtering functions and tone generation (ringing,
audible feedback tones and DTMF signal). An analog front end offers three analog inputs
and two analog outputs with programmable amplifiers.
The IOM-2 interface allows a modular design with functional extensions (e.g. acoustic
echo cancellation, tip/ring extension, modem extension, answering machine, video or
data terminal) by connecting other voice/data devices to the SCOUT.
In the P-MQFP-44 package (PSB21381/3) only a serial microcontroller interface (SCI) is
supported.
In the P-MQFP-64 package (PSB21382/4) a serial and parallel microcontroller interface
are supported. A clock signal and a reset input and output pin complete the
microcontroller interface.
The SCOUT is a CMOS device and operates with a 3.3 V or 5 V supply.
