12、on) is the United Nations Specialized Agency in the field of telecommunications. The IT Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to
13、 standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets every four years, establishes the topics for study by the ITU-T Study Groups which, in their turn, produce Recommendations on these topics. The approval of Recommendatio
14、ns by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation, the expression “Admini
15、stration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Pr
16、operty Right. The ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, the ITU had not received

32、38 39 39 40 Recommendation Q.831 (10/97) V Introduction V5 interfaces, as described in Recommendations G.964 and G.965, operate between a Local Exchange (LE) and an Access Network (AN) to support various narrow-band Integrated Services Digital Network (ISDN) and Public Switched Telephone Network (PS
33、TN) services. These interfaces and their associated user ports need to be managed by the Operations Systems (OSs) within the Telecommunications Management Network (TMN). This management is performed by means of 43 interfaces. The companion Recommendation Q.824.5 on configuration management defines h
34、ow the Q3 interface of an AN handles the configuration information for V5 interfaces and their associated user ports. This Recommendation specifies the extension to include fault and performance management. Fault management of V5 interfaces and associated user ports is part of a management activity
35、which back to its normal state of operation whenever a deviation occurs. Performance management of V5 interfaces and associated user ports is part of a management activity which is employed in order to maintain the quality of service levels agreed with the customers. The activities undertaken in per
36、formance management are monitoring, analysis and problem alerting, diagnosis, optimization and control. A customer access is considered as being that part of the local network which extends from the network termination equipment up to and including the exchange termination. Here, only the parts of t
37、he activities are covered which are related directly to a V5 interface between a LE and an AN or to that part of the customer access which extends from the AN to the network termination equipment. An ISDN access extends to but does not include the T reference point. An analogue access extends to and
38、 may include the Customer Premises Equipment (CPE).

User ports
39、represent the different configurations for Line Circuit (LC), Line Termination (LT), Exchange Termination (ET) and Network Termination (NT) as given in Figure 2 of the V5 specifications in Recommendations G.964 and G.965. For leased lines (semi-permanent lines), this Recommendation only covers aspec
40、ts which are common to PSTN and ISDN. With regard to fault and performance management, the TE and LL UP for leased lines are under the control of the access network only. This Recommendation details only those functions and management information model components for which V5 specific descriptions a
41、re required. However, the use of other components which may be applicable from other specifications is not precluded. In this case, combined applications vi Recommendation 4.831 (10197) incorporating both V5 specific and more generic aspects would result. For example, if log control is to be provide
42、d in conjunction with the V5 specific alarm reporting function (see Annex A), then other specifications (e.g. Recommendation X.735) are available to define this. The management information model described in this Recommendation complements that for configuration; both information models will normall
43、y share the same physical interface. Recommendation Q.831 (10/97) vii Recommendation 4.831 FAULT AND PERFORMANCE MANAGEMENT OF V5 INTERFACE ENVIRONMENTS AND ASSOCIATED CUSTOMER PROFILES (Geneva, 1997) 1 Scope This Recommendation specifies the 43 interface between a Local Exchange (LE) and an Access
44、Network (AN) and the Telecommunications Management Network (TMN) for the support of fault and performance management functions for V5 interfaces, as described in Recommendations G.964 8 and G.965 9, and their associated user ports. The management of transmission, of media, and of services which are
45、not related to V5 interfaces is outside the scope of this Recommendation, as is the management of equipment. and line circuits at the user ports associated with the V5 interface is going to be defined in the future Recommendation 4.835. The location of the 43 interface to which this Recommendation r
46、efers is specified in Recommendation 4.824.5 i 81. This Recommendation does not constrain the logical or physical size of the access network or its geographical dispersion. Existing protocols are used where possible, and the focus of this Recommendation is on defining the object models. The definiti
47、on of Operations Systems (OSs) functionality is outside the scope of this Recommendation. I This Recommendation includes the logging of faults and related functions.
