The two-channel codec filter PSB 2132 SICOFI
which provides independent filter structures for both channels. Its analog I/O pins are
used to connect to external subscriber line interface circuits (SLICs). Their signals are
internally routed to the analog-to-digital and digital-to-analog converters (ADC, DAC).
The signaling pins carry line status and control information to and from the SLICs. Two
programmable clock outputs are available, one of which can be used for generating a
ringing signal (RGEN). The SICOFI
768 kbit/s IOM-2 bus, often used in terminal equipment. The digitized voice band signals
are available as A-Law or µ-Law codes within selectable 8-bit time slots.
The SICOFI
serial interface to a microcontroller. The access mechanism is very simple, and can be
implemented with as few as three I/O ports.
