A.5.1 TMF-Defined Probable Cause

The following report lists the probable causes defined by the TMF:

"UNIDENTIFIED": for alarms that do not match any other string below. EMS shall in this
case fill out the additional text field as much as possible.
"AIS": alarm indication signal
"AMS": Alternate modulation signal
"AU-AIS": AU alarm indication signal
"BER_SD": signal degrade (includes receiver degrade)
"BER_SF": signal fail (includes receiver failure and excessive BER)
"DCC_FAILURE": Data Communication Channel Failure
"EMS": EMS system alarm
"EMS_ALM_LOSS": The 1st notification that the EMS may supply after 1 or more notifications
for protection switch, TCA, alarm, or file transfer status have been discarded by the EMS
while other events have not been discarded
"EMS_LIFECYCLE_LOSS": The 1st notification that an EMS may supply after 1 or more events
of type OC/OD/AVC/SC/RC have been discarded by the EMS
"EMS_ALM_AND_LIFECYCLE_LOSS": The 1st notification that an EMS may supply after 1 or more
notifications for protection switch, TCA, alarm, or file transfer status, and 1 or more
events of type OC/OD/AVC/SC/RC have been discarded by the EMS
"EQPT": equipment alarm
"ENV": Environmental/external cause
"FOP_APS": failure of APS protocol
"LCD": Loss of Cell Delineation (from TC Adaptor part of ATM NI)
"LOF": loss of frame (when distinguished from LOS)
"LOM": loss of multiframe (SDH only, since not an alarm in GR-253)
"LOP": loss of pointer
"LOS": loss of signal
"MS-AIS": MS alarm indication signal
"OSC-AIS": Optical Supervisory Channel alarm indication signal
"OSC_BER_SF": Optical Supervisory Channel signal fail/RX fail/excessive BER
"OSC_FERF": Optical Supervisory Channel Far End Receive Failure
"OSC_LOF": Optical Supervisory Channel Loss of Frame
"OSC_LOS": Optical Supervisory Channel Loss of Signal
"OSC_SD": Optical Supervisory Channel signal degrade
"PLM": payload label mismatch (when reported as an alarm)
"RAI": remote alarm indication (sometimes reported as RDI)
"SECURITY_VIOLATION": security violation
"SSF": server signal fail
"TCM-AIS": Tandem Connection Sink - Incoming Alarm Indication Signal
"TCM-LOS": Tandem Connection Sink - Loss of Tandem Connection Signal
"TCM-OAI": Tandem Connection Sink - Outgoing Defect Indication (same/similar to Alarm
Indication)

Indication)
"TCM-SD": Tandem Connection Sink - Signal Degrade
"TCM-SSF": Tandem Connection Sink - Server Signal Fail
"TCM-TIM": Connection Sink - Trace Identifier Mismatch
"TCM-UNEQ": Tandem Connection Sink - Unequipped
"TIM": trace identifier mismatch (when reported as an alarm)
"TU-AIS": TU alarm indication signal
"TX_DEGRADE": transmitter degrade, including laser degrade
"TX_FAIL": transmitter failure, including laser failure
"UAT": Unavailable Time
"UNEQ": payload unequipped
"VC-AIS": VCL/VCC TP Alarm Indication Signal
