24 hr T1 Performance Data Summary
Command
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 (Cyclic 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 DIDCSU 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.
