Refer to ITU-T Recommendation I.610 for complete information on the
structures and functions of OAM cell generation, detection, and processing.
defined in Recommendation I.610.
done at the software level due to the low bandwidth of OAM traffic (less than 1%
of the bandwidth of active connections).
For reporting defect indications in the forward direction.
For reporting remote defect indications in the backward direction.
For continuously monitoring the continuity of a connection. A continuity cell is used
periodically to check whether a connection is idle or has failed.
Used for:
For estimating performance and for reporting performance estimations in the backward
direction.
For activating/deactivating performance monitoring and continuity check.
(For use by end-systems only.)
Table 7-1 below lists the OAM functions of the F4 and F5 OAM flows, as
The RS8234 internally supports the following functions as described in I.610:
• Full Performance Monitoring functions (designed for estimating
• Detection of OAM cells, and routing them as directed by the host
• Generation of OAM cells, as directed by the host
Implementation of the full range of functions in processing OAM cells will be
on-demand connectivity monitoring,
fault localization, and
pre-service connectivity verification.
