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 16.5 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 16.5 for details.
LOTC
SR1.5
Loss of Transmit Clock. Set when the TCLK pin has not transitioned for one channel
time (or 5.2
ms). 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.
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 RPOSI and
RNEGI.
RYEL
SR1.2
Receive Yellow Alarm. Set when a yellow alarm is received at RPOSI and RNEGI.
LRCL
SR1.1
Line Interface Receive Carrier Loss. Set when a red alarm is received at RTIP and
RRING.
RLOS
SR1.0
Receive Loss of Sync. Set when the device is not synchronized to the receive T1
stream.
