IMPACT DESCRIPTION
Service ES violations threshold
Degradation crossing alert for section
layer at local NE. A one
second interval in the
transmission from the far
end originating NE has had
an error at the section layer
causing an Errored Second
Section (ESS). ESS errors
have exceeded the user
definable threshold level.
Service Errored seconds threshold
Degradation crossing alert for reported
port.
Service Excessive Bit Error Rate
Affecting count.
Service Cell bus hard failure.
Affecting
Service No input signal is being
Outage provided at the far end.

SUGGESTED COURSE OF ACTION
Check input levels and signal
sources. Increase threshold
settings if necessary. Check
local requirements for proper
levels.
Check input levels and signal
sources. Increase threshold
settings if necessary. Check
local requirements for proper
levels.
Applies to all SONET cards.
Each of these alarms indicate a
switch fabric failure. Check
alarm messages, is the failure
on both buses? One card? All
cards? If single card failure,
remove from backplane, check
pins in backplane connector,
and reseat. One card failure
could pull down the entire bus.
Pull each card out one at a time
starting with protect, check the
pins in the backplane connector,
monitor system traffic for
recovery, then reseat the card.
Perform switch over via GUI or
craft interfaces before pulling
EIMs if necessary. Do not pull
the working cards. Repeat
procedure for SC TEIM in slot
18 at the rear of the shelf. This
is a bus termination and the
system will crash without it.
Check input connections at the
far end and transmitting
equipment into the far end low
speed facility.
