list measurements ds1

Last Updated : Aug 14, 2023 |
Use list measurements ds1 to list performance measurements on a DS1 link. The performance measurements of a DS1 link indicate the quality of the DS1’s physical interface between the system and a far-end system.
Use list measurements ds1-facility to see link performance measurements on a DS1 Converter facility. The DS1 Converter complex consists of two DS1Cs connected by one to four DS1 facilities. Using this complex, you can extend the distance between two port networks up to 100 miles, thereby extending the range of the optical fiber link within limited bandwidth (96 channels). A DS1C complex can be used in a direct connectivity configuration or a Center Stage Switch configuration. The DS1 converters may be connected to an Expansion Interface (EI) or a Switch Node Interface (SNI) through a metallic connection.

list measurements ds1 field descriptions

Field
Description
Counted Since
The start time and date when the associated measurement counters were cleared or the DS1 media module or facility was administered.
Valid 15-Minute Intervals in Last 24 Hours
The total number of 15-minute intervals int the past 24-hour period that contain valid data. (0–96)
Seconds Elapsed In Current Interval
The number of seconds from the beginning of the current 15-minute interval. (0–900)
ESF Error Events
Test
Pattern
Synchronized
Loopback/Span Test Bit-Error Count
Test Duration
Worst 15-Minute Interval (Date, Time, Count)
The date, end time, and error count (from 0 to 900 in increments of four) of the 15-minute interval in the previous 24-hour period that contains the maximum value for each error category.
24-Hour Count
The sum of all valid 15-minute counts for the previous 24-hour period for each error category. (0–65535)
Current Interval Count
The error count for the current (incomplete) 15-minute interval for each of the four error categories. (0–900 or N/A if data for the 15-minute interval is invalid)
Category
The categories correspond to measurement error counters:
  • Errored Seconds — the value of the errored seconds counter for the specified 15-minute interval (0 - 900 or N/A if data for the 15-minute interval is invalid).
  • Bursty Errored Seconds — the value of the bursty errored seconds counter for the specified 15-minute interval (0 - 900 or N/A if data for the 15-minute interval is invalid).
  • Severely Errored Seconds — the value of the severely errored seconds counter for the specified 15-minute interval(0 - 900 or N/A if data for the 15-minute interval is invalid).
  • Unavailable/Failed Seconds — the value of the failed seconds counter for the specified 15-minute interval (0 - 900 or N/A if data for the 15-minute interval is invalid).
  • Controlled Slip Seconds
  • Loss of Frame Count
