scope:

The present document addresses the network management architecture, functions, and protocol for LCS operations and maintenance. The information model included here defines the managed entities and how they are addressed for purposes of operations and maintenance activities.

There is a requirement for the network management interface to be open to allow interoperation between LMUs and GMLCs of different manufacturers working to the same SMLC. The present document addresses this requirement from an operations and maintenance point of view, which allows this interworking to take place. It shows the split of network management functions between GMLC, SMLC and LMU. The procedures and coding of the messages are specified in detail. In practice, in addition to the present document, it is necessary that the content of manufacturer-dependent information fields be specified to fulfil the functionality.

It is essential for operation that a SMLC can handle the functions used by all its LMUs. Therefore, all items in the present document are considered mandatory unless otherwise indicated in the present document.

NOTE: This version contains only the SMLC-LMU interface. Other work will be undertaken in the future.
