Interrupt Request:
The signal is activated when a
conference overflow is detected. The microproces-
sor may determine the specific conference in over-
flow by reading the conference status register
(CST). The interrupt is maskable. INT is an open
drain output, thus a ‘wired-or’ combination of inter-
rupt request outputs of several MUSAC-As is pos-
sible (a pull up resistor is necessary).
Synchronization Pulse:
The MUSAC-A is syn-
chronized relative to the PCM system via this line.
PCM-Input Ports:
Serial data is received at these
lines at standard TTL levels.

PCM-Input Port / Tristate Control:
In standard
configuration these pins are used as input lines, in
primary access configuration they supply control
signals for external devices.
PCM-Input Port / Data Clock:
In standard config-
uration IN3 is the PCM-input line 3, in primary
access configuration it provides a 2048-kHz data
clock for the synchronous interface.
Address for Direct Register Access:
These pins are only active if a demultiplexed
μ
P-interface mode is selected.
If A1 is not connected it will be set to ground inter-
nally.
