Alarm Description Solution
SRP1/1 Side A Keepalive
Failure (MAC)
MAC failure is detected Check transport span for problems.
Typically SRP ring traverses a SONET
layer connection, creating this error.
SRP1/1 Side A Keepalive
Failure (SLOS)
SONET section loss of signal Check fiber for breaks, power level, and
connectivity.
This is a SONET Layer 1 issue with fiber.
SRP1/1 Side A Keepalive
Failure (SLOF)
SONET section loss of frame Check the fiber for degradation in (power
level) or clocking (internal versus line).
SRP1/1 Side A Keepalive
Failure (LSD)
SONET line signal degrade Check the affected fiber, transmit and
receive ports. Check power level.
This is a SONET Layer 1 issue with
signal degrade.
SRP1/1 Side A Keepalive
Failure (LSD)
SONET line signal degrade Check the neighbor
node/transport/regenerator for SONET
Layer 1 issues (LOS, LSF).
This is a SONET Layer 1 issue with an
intermediate unit (usually transport
connection or regenerator) forwarding an
AIS.
SRP1/1 Side A Keepalive
OK
Keepalive failure removed;
Layer 2 Keepalive receiving
correctly
None.
RPR-IEEE1/1 span
WEST Keepalive
Failure (MAC)
MAC failure is detected Check transport span for problems.
Typically RPR ring traverses a SONET
layer connection, creating this error.
RPR-IEEE1/1 span
WEST Keepalive Failure
(SLOS)
SONET section loss of signal Check fiber for breaks, power level, and
connectivity.
This is a SONET Layer 1 issue with fiber.
RPR-IEEE1/1 span
WEST Keepalive
Failure (SLOF)
SONET section loss of frame Check the fiber for degredation in (power
level) or clocking (interval versus line).
RPR-IEEE1/1 span
WEST Keepalive
Failure (LSD)
SONET line signal degrade Check the affected fiber transmit (TX)
and receive (RX) ports. Check the power
level.
This is a SONET Layer 1 issue with
signal degradation.
