13.2.4 Recommendation G.829
G.829 is based on the principle of monitoring block errors, allowing measurements to
be made in-service. The recommendation defines the block size, number of blocks per
SDH frame, number of blocks transmitted per second and the error detection code
(EDC) to be used for the various SDH bit rates that your ANT-5 supports.
13.2.5 Recommendation M.2100
Recommendation M.2100 specifically 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. If this is the case, the line remains in service, but must continue to
be monitored for a further 7 days. The measurement procedures are defined in
M.2110 and M.2120. The limit values are derived from the performance parameters
specified in G.821 and G.826.
13.2.6 Recommendation M.2101
This recommendation is very close to M.2100 in terms of purpose and format, but it
deals exclusively with SDH systems. Recommendation M.2101 for SDH systems can
be considered as a sister recommendation to M.2100 for PDH systems.
