NAME AND DESCRIPTION
Loop Up Code Detected. Set when the loop up code as defined
in the RUPCD register is being received. See Section
details.
Loop Down Code Detected. Set when the loop down code as
defined in the RDNCD register is being received. See Section
for details.
Loss of Transmit Clock. Set when the TCLK pin has not
transitioned for one channel time (or 5.2µs). Will force the
RLOS/LOTC pin high if enabled via CCR1.6. Also will force
transmit side formatter to switch to RCLKO if so enabled via
TCR1.7.
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 1s code is
received at RPOSI and RNEGI.
Receive Yellow Alarm. Set when a yellow alarm is received at
RPOSI and RNEGI.
Line Interface Receive Carrier Loss. Set when 192
consecutive 0s have been detected at RTIP and RRING. See
Table
Receive Loss of Sync. Set when the device is not synchronized
to the receive T1 stream.
