Command Description
En Errored Seconds (ES): A second with one or more AIS, LOS, or LOF defects.
Un Unavailable Seconds (UAS): Counted for every second in which an Unavailable Signal State
occurs with the onset of 10 contiguous SES errors. It is also defined as the number of seconds
a service is unavailable due to a Loss of Frame (LOF) condition. The UAS condition is stopped
when the failure condition clears.
Bn Bursty Seconds (BES): A second having between 2 and 319 CRC-6 (Cyclical Redundancy Check
error events.
Sn Severely Errored Seconds (SES): This error counts one second intervals with an AIS or CRC
error.
Ln Loss of Signal (LOS) Seconds: A second during which the QPRI is in a Loss of Signal state. LOS
is declared upon detecting 175 consecutive zeros, it is cleared with the receipt of the next 1
bit.
Fn Severely Errored Framing (SEF) Seconds: Those seconds in which two or more framing bit
errors occur within a 3-millisecond period. In ESF mode, this interval may or may not coincide
with an ESF multiframe.
Dn Loss-of-Frame (LOF) Seconds: An LOF alarm is declared when a 3-second interval of
continuous Out-Of-Frame (OOF) or Loss-Of-Signal (LOS) state is detected. If at least 10
seconds elapse without an LOS or LOF error, the LOF alarm is cleared.
On Out-of-Frame (OOF) Seconds: A condition when any three of four consecutive frame bits
received from the T1 line are incorrect.
An Alarm Indication Signal (AIS) Seconds: A count of one-second intervals containing one or more
AIS defects. AIS is an unframed All-Ones bit pattern that indicates an alarm condition exists
upstream in a circuit leading to the downstream equipment. This is also called an All-Ones
Keep-Alive or Blue Alarm Signal. An AIS defect is declared when there are 3 or fewer zeros in
512 bit times and there is an LOF defect. It is cleared when there are 3 or more zeros in two
frames or the LOF defect no longer exists.
Cn Controlled Slip Seconds: This error indicates that in a one second interval one or more slip
events occurred. An accurate count of controlled slips that occur can only be made at the
terminating network element where the slips take place.
The current version of the firmware does not support this feature.
