Evaluation According to ITU-T G.828
G.828 provides a precise block length for each bit rate as opposed to G.826.
ES, SES, BBE, UAS and SEP are evaluated.
Pass/Fail result is in conjunction with path allocation between 0.1 and 100%.
G.828 evaluation can be performed on the following events:
B1
B2
MS-REI
B3
HP-REI
LP-BIP
LP-REI
Bit errors (TSE)
Evaluation of the near end and far-end is possible, however far-end evaluations can only be made if REI is available.
Bit errors can be evaluated for:
Unframed patterns
Framed patterns and bulk signals
Overhead bytes E1/E2 (order wire), F1/F2 (user), D1 - D3 and D4 - D12 (DCC) in the SDH overhead (SOH and
POH)
Bit error evaluation is disabled because G.828 evaluates block errors.

Evaluation According to ITU-T G.829
G.829 is based on the principle of monitoring block errors in service.
ES, SES, BBE and UAS are evaluated.
G.829 evaluation can be performed on the following events:
B1
B2
MS-REI
Bit errors (TSE)
Evaluation of the near end and far-end is possible, however far-end measurement can only be made if REI is available.
Bit errors can be evaluated for:
Unframed patterns
Framed patterns and bulk signals
Overhead bytes E1/E2 (order wire), F1/F2 (user), D1 - D3 and D4 - D12 (DCC) in the SDH Overhead (SOH
and POH)
