The frame synchronization
output of framer recovered
from the incoming serial data
stream.
It is a gapped clock signal
output that is used to indicate
RXDAT serial data output.
RXGAPCK clock polarity and
behavior are programmable
and have several options (see
Section
Used to indicate chosen
Overhead bits that output on
RXDAT. This output has a
clock pulse for each position
of the chosen group of
Overhead bits for the specific
DS3/E3 mode. Its polarity is
programmable.
