Chapter 27 Alarms and Statistics
APS Alarms
Clear APS Deactivated APS line is down.
Minor APS Lines looped APS line is looped.
Minor APS Remote Signal
Failure A remote signal failure indicates that there is a problem with the
far end signaling information in the K1/K2 bytes.
Minor APS Channel Mismatch Can happen in only bidirectional mode and indicates that there is
a problem with the underlying APS channel protocol. The receive
K2 channel number does not equal the transmit K1 channel
number.
Minor APS Protection Switch
Byte Failure Protection Switch Byte (PSB) failure. In bidirectional mode,
indicates that there is an invalid K1 byte. The receive K1 request
does not match the reverse request and is less than the transmit K1
request. In all modes, a PSB alarm indicates that K1/K2 protocol
is not stable.
Minor APS Far-End Protection
Failure Far-end protection failure indicates that the far end’s protection
line is failing. When there is Signal Failure on the protection
channel, the remote end sees Far End Protection Fail.
Minor APS Architecture
Mismatch Architecture mismatch means that the APS configuration on one
end of the line does not match the APS configuration at the other
side of the line. Specifically GR-253 at one end and ITUT at the
other or 1+1 at one end and 1:1 at the other.
Info APS Init/Clear/Revert A BXM APS event indicating that the BXM APS has been
initialize, or a clear switch or a revert switch has occurred.
Info Cannot perform a
Clear/Revert switch A BXM APS event indicating that the BXM APS was unable to
perform a clear or revertive switch.
Info APS Manual switch A BXM APS event indicating that the BXM APS has performed
a user-requested manual switch.
Info Cannot perform a
Manual switch A BXM APS event indicating that the BXM APS was unable to
perform a user-requested manual switch.
Info APS Signal Degrade
LoPri switch A BXM APS event indicating that the BXM APS performed a
switch due to a high-priority signal degrade condition. An
automatically initiated switch due to a “soft failure” condition
resulting from the line BER exceeding a preselected threshold
(
cnfapsln ).
Info Cannot perform a Signal
Degrade LoPri switch A BXM APS event indicating that the BXM APS was unable to
perform a switch due to a low-priority signal degrade condition.
Info APS Signal Degrade
HiPri switch A BXM APS event indicating that the BXM APS performed a
switch due to a high-priority signal degrade condition. An
automatically initiated switch due to a “soft failure” condition
resulting from the line BER exceeding a preselected threshold
(
cnfapsln ).
Info Cannot perform a Signal
Degrade HiPri switch A BXM APS event indicating that the BXM APS was unable to
perform a switch due to a high-priority signal degrade condition.
