ATM OAM

OAM in the ITU-T I.610 recommendation (02/99) and Operation Administration and Maintenance in LUCENT APC User Manual (03/99).

Whichever expansion is adopted, OAM provides a way of detecting faults, isolating faults, and monitoring network performance without interrupting ongoing services. By inserting OAM cells, which are constructed in the standard ATM cell format, in cell streams, you can obtain specific information about the network.
