NAME AND DESCRIPTION
LUP
SR1.7
Loop Up Code Detected. Set when the loop up code as
defined in the RUPCD register is being received. See
Section 20 for details.
LDN
SR1.6
Loop Down Code Detected. Set when the loop down code
as defined in the RDNCD register is being received. See
Section 20 for details.
LOTC
SR1.5
Loss of Transmit Clock. Set when the TCLK pin has not
transitioned for one channel time (or 5.2 us). Will force the
RLOS/LOTC pin high if enabled via CCR3.5. Also will
force transmit side formatter to switch to RCLK if so enabled
via TCR1.7.
RSLIP
SR1.4
Receive Elastic Store Slip Occurrence. Set when the
receive elastic store has either repeated or deleted a frame.
RBL
SR1.3
Receive Blue Alarm. Set when an unframed all one’s code
is received at RPOS and RNEG.
RYEL
SR1.2
Receive Yellow Alarm. Set when a yellow alarm is received
at RPOS and RNEG.
RCL
SR1.1
Receive Carrier Loss. Set when a red alarm is received at
RPOS and RNEG.
RLOS
SR1.0
Receive Loss of Sync. Set when the device is not
synchronized to the receive T1 stream.
