Abstract :
The principles of operation and maintenance (OAM) for broadband ISDN access, as well as some general OAM rules for an asynchronous transfer mode (ATM) network, are discussed. Standardization of the OAM functions and mechanisms for the ATM layer, which is based primarily on CCITT Recommendations, is considered. Issues regarding OAM flow at the ATM layer are examined. It is seen that although references can be made both to basic and primary rate ISDN, new solutions are necessary for the OAM of B-ISDN. Issues requiring further study are identified.<>
