Table 4-10. 15-Minute Performance Registers Display Field Descriptions
Field Description
INT (Interval):
(display field)
The interval number for the ninety-six 15-minute intervals preceding the
current interval, with 01 being the most recent.
ES (Errored Seconds):
(display field)
The occurrence of a Loss of Frame or a CRC6 error in a one-second period is
known as an errored second. This field displays the number of errored seconds
that have occurred.
FS (Failed Seconds):
(display field)
Each one-second period during the occurrence of a Failed Signal State (ten
consecutive errored seconds) is known as a failed second. This field displays the
number of severely errored seconds that have occurred.
SES (Severely Errored
Seconds): (display field)
A one-second period in which three hundred twenty (320) or more CRC6
errors have occurred is known as a severely errored second. This field displays
the number of severely errored seconds that have occurred.
BES (Bursty Errored
Seconds): (display field)
(displayed for T1 links only)
A one-second period in which more than one but less than 320 CRC6 errors
has occurred is known as a bursty errored second. This field displays the
number of bursty errored seconds that have occurred.
