Evaluation according to ITU-T M.2100
M.2100 applies to commissioning and maintenance. Commissioning consists of a 15-minute line up phase followed by a 24-hour
in-service measurement. Once the line up phase is completed successfully, errors may occur within certain limits.
ES, SES and UAS are evaluated.
Pass/Fail results are based on threshold values S1 and S2 for ES and SES.
Settings for S1 and S2:
- Path allocation: 0.1 to 100%
- BISO multiplication factor: 0.1 to 100
The M.2100 evaluation can be performed on the following events:
- FAS bit errors (FAS2, FAS34, and FAS140)
- CRC-4 errors
- EBIT errors
- Bit errors (TSE)
Evaluation is made at the “Near End” and at the “Far End” for PCM-30/31 signals with CRC
Bit errors can be evaluated for:
- Unframed patterns
- Framed patterns and bulk signals
- n x 64 kbit/s
Since M.2100 evaluates bit errors, facilities for evaluating block errors are disabled.
