Line Overhead BIP-8 Code Violation. Indicates that parity
errors were detected at the Line layer of the incoming
SONET signal. This is calculated over the Line OH, Path OH,
and payload of each STS-1. This is an error LED
STS Path Status LED. Indicates if any of the errors or
alarms within this portion of the overhead are being received.
This is a status LED.
STS Path Alarm Indication Signal. Indicates if an alarm is
being received from upstream Path terminating equipment.
This is an alarm LED.
STS Path Remote Defect Indicator. Indicates that a remote
alarm is being received from downstream Path terminating
equipment. The G1 byte of the SONET Path Overhead is
used for this indicator. This is an alarm LED.
STS Path Loss of Pointer. Indicates that an invalid Pointer
has been received or a Pointer loss has been detected on the
incoming SONET signal. This is an alarm LED.
STS Path Remote Error Indicator. Indicates that an error
count is being received from downstream Path terminating
equipment. An REI is also known as a Far-End Block Error
(FEBE). This is an error LED.
STS Path Pointer Adjustments. Indicates Pointer offsets or
adjustments between the STS payload and the OC-N frame
are occurring. This is a status LED.
STS Path Overhead BIP-8 Code Violations. Indicates that
parity errors were detected at the Path layer of the incoming
SONET signal. This is calculated over the Path OH and
payload of each STS-1. This is an error LED.
STS Path Unequipped Payload. Indicates that a 00h pattern
has been detected in the C2 byte. This byte is being received
from Path terminating equipment. This is an alarm LED.
Virtual Tributary Status LED. Indicates if any of the errors
or alarms within this portion of the overhead are being
received. This is a status LED.
This section is only available when VT-1.5, VT-2 or VT-6 is
