NAME AND DESCRIPTION
Loop Up Code Detected. Set when the repeating ...00001...
loop up code is being received.
Loop Down Code Detected. Set when the repeating ...001...
loop down code is being received.
Loss of Transmit Clock. Set when the TCLK pin has not
transitioned for one channel time (or 5.2 s). Will force the
RLOS/LOTC pin high if enabled via CCR1.6. Also will force
transmit side formatter to switch to RCLK if so enabled via
TCR1.7. Based on RCLK.
Receive Elastic Store Slip Occurrence. Set when the receive
elastic store has either repeated or deleted a frame.
Receive Blue Alarm. Set when an unframed all ones code is
received at RPOS and RNEG.
Receive Yellow Alarm. Set when a yellow alarm is received at
RPOS and RNEG.
Receive Carrier Loss. Set when 192 consecutive 0s have been
detected at RPOS and RNEG.
Receive Loss of Sync. Set when the device is not synchronized
to the receive T1 stream.
