7、endation is to define the Q3 interface between a network element for customer access (i.e. local exchange, access network) and the telecommunications management network (TMN) for the support of line and line circuit test functions and the associated management for ISDN and analogue customer accesses
8、 which are connected either directly to a local exchange or remotely at an access network and across V5.1 and/or V5.2 interfaces to a local exchange. The focus of this Recommendation is on defining an object model based on ITU-T Recommendations Q.824.0, Q.824.5, Q.831, and X.745. Existing protocols
9、are used where possible. The definition of Operations System (OS) functionality is outside the scope of this Recommendation. Source ITU-T Recommendation Q.835 was prepared by ITU-T Study Group 4 (1997-2000) and was approved under the WTSC Resolution No. 1 procedure on the 26th of March 1999. Keyword

Recommendation Q.835 (03/99) iiFOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardiz
11、ation 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 standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC
12、), 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 Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of info
13、rmation technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation the term recognized operating agency (ROA) includes any individual, company, corporation or governmental organization that operates a publi
14、c correspondence service. The terms Administration, ROA and public correspondence are defined in the Constitution of the ITU (Geneva, 1992). INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a cla
15、imed Intellectual Property 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
16、ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database. ITU 1999 All

35、6 Recommendation Q.835 (03/99) vii Introduction Line and circuit testing of analogue customer accesses and ISDN customer accesses is part of a management activity which is performed by the operator in order to detect failure conditions and to bring the customer access back to its normal state of ope
36、ration whenever a deviation occurs. 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 these parts of the activity are covered which are related directly to that part of
37、 the customer access which extends from the local exchange to the network termination equipment. An ISDN access extends to but does not include the T reference point. An analogue access extends to and may include the customer premises equipment (CPE) (see Figure 0). In Figure 0 both customer access
38、scenarios are illustrated: a) Direct access case for PSTN and ISDN customer to a local exchange (LE), which is shown in the top of Figure 0; b) Remote access case for PSTN and ISDN customer as well as for leased lines (semi-permanent lines) via an access network (AN) and across the V5.1 and/or V5.2
39、interface (as specified in Recommendations I.414, G.964 and G.965), shown in the bottom part of Figure 0. The shaded areas are subject to line and circuit testing and the associated management as presented within this Recommendation is based on the specifications within Recommendation Q.831. T040986

42、eneva, 1999) 1 Scope This Recommendation specifies the Q3 interface between a network element for customer access (i.e. local exchange, access network) and the Telecommunications Management Network (TMN) for the support of line and line circuit test functions and the associated management for ISDN a
43、nd analogue customer accesses which are connected either directly to a local exchange or remotely at an access network and across V5.1 and/or V5.2 interfaces to a local exchange. It is not mandatory to implement the test and measurements specified in this Recommendation for all types of customer acc

The focus of this Recommendation is on defining an object model based on Recommendation X.745 22. Existing protoc
