This standard provides an overview and general discussion of the models@ terminology@ and principles utilized to define needed management functionality in customer and network equipment for ISDN management operations. This standard covers the general concept of the ISDN management process and states the functional ISDN maintenance strategies. Standards in this set refer to other American National Standards for specification of the details of communications interfaces required for ISDN management. This series of standards does not directly address the maintenance and operations of Signaling System #7 (SS7) networks. This is expected to be addressed in other American National Standards. Purpose The purpose of this standard is to provide an overview of the set of standards on management operations for Integrated Services Digital Networks (ISDNs) and to establish the principles for the maintenance and operations needed for overall management of ISDNs. This set of standards is intended to establish needed management functionality in customer and network equipment@ particularly from the perspective of maintenance functionality available at network interfaces between telecommunication carriers; at the network boundary on the customer's premises; and with operations systems. Structure of this standard Clause 1 describes the scope@ purpose@ and structure of this standard. Clause 2 lists the normative references. Clause 3 provides definitions common to the general discussion of ISDN management or utilized by more than one of the other standards in the set. Clause 4 provides general ISDN management models. Clauses 5 and 6 provide ISDN management principles and management strategies that will be built upon by the other standards in the set. Annex A provides examples of potential ISDN management services. Annex B is a bibliography@ which provides a list of related standards. Structure of the set of American National Standards for ISDN management operations The following American National Standards deal with the maintenance aspects of ISDN management operations. Each standard is intended to be capable of standing on its own: ANSI T1.216@ Telecommunications ?C Integrated services digital network (ISDN) management ?C Basic rate physical layer ANSI T1.217@ Telecommunications ?C Integrated services digital network (ISDN) management ?C Primary rate physical layer ANSI T1.218@ Telecommunications ?C Integrated services digital network (ISDN) management ?C Data link and network layers Other work is in progress that may result in standards dealing with ISDN management services and their associated managed objects.
