† After RESET is deasserted, the channel is in the default framing mode, as a function of the DS1/CEPT pin.
‡ Asserting this pin low will initially force RDY to a low state.

Receive Framer Clock. Output receive framer clock signal used to
clock out the receive framer output signals. In normal operation, this is
the recovered receive line clock signal.
Receive Framer Data. This signal is the decoded data input to the
receive elastic store. During loss of frame alignment, this signal is
forced to 1.
Receive Frame Sync. This active-high signal is the 8 kHz frame syn-
chronization pulse generated by the receive framer. During loss of
frame alignment and signaling superframe or multiframe alignment, this
signal is forced to 0.
Receive Facility Data Link Clock. In DS1-DDS with data link access,
this is an 8 kHz clock signal. Otherwise, this is a 4 kHz clock signal. The
receive data link bit changes on the falling edge of RFDLCK.
