PCM Interface Example: Detail A
The pins DRA/B and DXA/B may be strapped together to form a multiplexed
bi-directional PCM port.

Signaling Interface
The SICOFI
4-μC Signaling Interface is used to monitor and control supervision and
signaling functions on up to four subscriber lines. The device generates interrupt signals
to indicate signaling status changes on any of the input pins.
The Signaling Interface consists of the following I/O pins and functions:
28 signaling pins (2 input pins, 2 output pins, and 3 user-configurable bi-directional
pins per channel),
Debouncing functions,
2 interrupts (one for each channel-pair), and
2 clock output signals (user configurable).
