MS-AIS
MSOH Alarm Indication Signal
. Indicates if an alarm is
being received from upstream MS terminating equipment.
This is an alarm LED.
APS
Automatic Protection Switching
. Indicates that the K1 and
K2 bytes on the incoming SDH signal have changed.
MS-RDI
MSOH Remote Defect Indication
. Indicates that a
downstream defect has occurred along the MS layer. (An RDI
is also known as a Far-End Remote Failure, FERF). This is
an alarm LED.
B2
MSOH BIP-8 Code Violation
. Indicates that parity errors
were detected at the MS layer of the incoming SDH signal.
This is calculated over the MSOH, HPOH, and payload of
each STM-n. This is an error LED
HP
HPOH Status LED
. Indicates if any of the errors or alarms
within this portion of the overhead are being received. This is
a status LED.
AU-AIS
AU Alarm Indication Signal
. Indicates if an alarm is being
received from upstream HP terminating equipment. This is an
alarm LED.
HP-RDI
HPOH Remote Defect Indication
. Indicates that a remote
alarm is being received from downstream HP terminating
equipment. The G1 byte of the HPOH is used for this
indicator. This is an alarm LED.
AU-LOP
AU Loss of Pointer
. Indicates that an invalid Pointer has
been received or a Pointer loss has been detected on the
incoming SDH signal. This is an alarm LED.
HP-REI
HPOH Remote Error Indication
. Indicates that an error
count is being received from downstream HP terminating
equipment. An REI is also known as a Far-End Block Error
(FEBE). This is an error LED.
AU-PTR
AU Pointer Adjustments
. Indicates Pointer offsets or
adjustments between the payload and the STM-N frame are
occurring. This is a status LED.
B3
HPOH BIP-8 Code Violations
. Indicates that parity errors
were detected at the HP layer of the incoming SDH signal.
This is calculated over the HPOH and payload of each STM-
N. This is an error LED.
