scope:

This ETS defines the characteristics of protocol suites for Q interfaces for transmission systems/equipments, as defined in CCITT Recommendations M.3010 [2] and G.773. Protocol suites for Q interfaces for other systems/equipments are to be specified in other ETSs. The interfaces will support bidirectional data transfer for the management of telecommunications systems.

This ETS defines:

- the layer services;

- the layer protocols;

- the application service elements and protocols;

- the conformance requirements to be met by an implementation of these interfaces.

This ETS does not define:

- the structure or meaning of the management information that is transmitted by means of the protocol suites;

- the manner in which management is accomplished as a result of the application protocol exchanges;

- the interactions which result in the use of the application layer protocols.
