NAME AND DESCRIPTION
LUP
SR1.7
Loop Up Code Detected. Set when the repeating ...00001...
loop up code is being received.
LDN
SR1.6
Loop Down Code Detected. Set when the repeating ...001...
loop down code is being received.
LOTC
SR1.5
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.
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 ones 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 192 consecutive 0s have been
detected at RPOS and RNEG.
RLOS
SR1.0
Receive Loss of Sync. Set when the device is not synchronized
to the receive T1 stream.
