Introduction

This series of standards on the Operations, Maintenance, and Administration Part (OMAP) define the functions, procedures, and entities for managing the Signalling System Number 7 (SS7) network.

The management functions of SS7 are divided into three main parts:

management functions located in the Telecommunications Management Network (TMN) (which means the Network Element Functions (NEFs) and the Operations System Functions (OSF) - see Recommendation M.3000). These functions include measurement collection, and cover TMN to TMN interactions;

management functions within the SS7 protocol itself (e.g., changeover, forced rerouting, subsystem management, etc.); and

management functions defined to enable verification and validation of routing tables, Circuit Identification Codes (CICs), etc. These functions may require communication within the signalling network, and for this, a separate protocol is defined. Such management functions are modeled as managed objects at the interface between the network elements and an operations system.

Of the three sets of management functions defined above, OMAP provides a) and c). Set b) can be modeled as existing within the "Layer Management Entities" of SS7, and the functions are defined in the standards pertinent to those layers.

OMAP interacts with all layers (i.e., with all the levels) of SS7 in order to effect control of the network.

This standard comprises six chapters:

• T1.116.0 gives the OMAP overview;

• T1.116.1 defines the SS7 managed objects;

• T1.116.2 defines SS7 monitoring and measurements;

• T1.116.3-2000 defines the SS7 management functions for managed objects that themselves require SS7 communication in the network, and also the OMAP Management Application Service Element (OMASE)-User where the logic of these functions (MRVT, SRVT LEF and LFS) is modeled;

• T1.116.4-2000 defines the Application Service Element (ASE) for those functions defined in

• T1.116.3-2000, i.e., OMASE; T1.116.5-2000 defines the SS7 testers; and

• T1.116.6-2000 is a Guide Book to Operations, Maintenance, and Administration Part (OMAP).

Figure A-1/T1.116.0 shows the relationship between TMN, SS7 management, and the OMAP standards.

OMAP uses principles of management defined in ITU-T Rec. M.3000 (TMN), and in ITU-T Recommendations of the X.700 series (OSI Management).
