This model is restricted to the Operations Systems toNetwork Element (Q3) interface.SourceITU-T Recommendation Q.826 was prepared by ITU-T Study Group 4 (1997-2000) and approvedunder the WTSC Resolution 1 procedure
8、 on 4 February 2000.ii ITU-T Q.826 (02/2000)FOREWORDThe International Telecommunication Union (ITU) is the United Nations specialized agency in the field oftelecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ ofITU. ITU-T is responsible for studying techn
9、ical, operating and tariff questions and issuing Recommendationson them with a view to 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, i
10、n turn, produce Recommendations on thesetopics.The approval of ITU-T Recommendations is covered by the procedure laid down in WTSC Resolution 1.In some areas of information technology which fall within ITU-Ts purview, the necessary standards areprepared on a collaborative basis with ISO and IEC.NOTE
11、In this Recommendation, the expression “Administration“ is used for conciseness to indicate both atelecommunication administration and a recognized operating agency.INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation mayinvolv
12、e the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence,validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or othersoutside of the Recommendation development process.As of the date of approval of this Recommend
13、ation, ITU had not received notice of intellectual property,protected by patents, which may be required to implement this Recommendation. However, implementors arecautioned that this may not represent the latest information and are therefore strongly urged to consult theTSB patent database. ITU 2001

40、lysis“ function in an exchange. The scope isfurther limited to the exchange aspects of circuit switched networks. This model is restricted to theOperations Systems to Network Element (Q3) interface (see ITU-T M.3010 1).The information to be managed is limited to the signalling systems DSS1 (Digital
41、SubscriberSignalling System No. 1), C5 (Signalling System CCITT No. 5), SS No. 7 (Signalling SystemNo. 7 ISUP (ISDN User Part) only) and R2 (Regional Signalling 2). (SS No. 7 with TUP(Telephone User Part) level 4 is not considered.) The information for routing purposes, which needsto be maintained b
42、y the manager, depends on the signalling systems used by the exchange. Thisinformation model can be applied for exchanges with the known standardized signalling systemsDSS1, SS No. 7, R2, C5. Because of the existence of different signalling systems, not all attributesand objects will be applicable f
43、or all exchanges. Information about applicability can be found in theobject classes behaviour.As this model only offers an element management layer view (i.e. limited to a switch) of the routinginformation, and only shows the partial view a switch has of its network environment, and does notshow the
44、 whole network picture, it does not provide all the information needed for network-widemanagement application.The information model covers the management of following aspects: incoming digit rebuilding; locally originating, locally terminating (up to recognizing that the DN (Directory Number)belongs
45、 to the exchange), and transit calls; digit analysis; circuit end point selection; outgoing digit preparation;as far as they are relevant for routing. It does not cover management of: DN portability (this is covered in ITU-T Q.18xx); CTM (Cordless Terminal Mobility);due to lack of stable requirement
46、s at the time of writing this Recommendation.The information model includes entry/exit points (via instances of specific OC) for: customer administration (see ITU-T Q.824.x 13); subscriber controlled input (no standard exists yet);IN (Intelligent Network) (see Q.18xx); specific treatments as, e.g. a
47、nnouncements.The information model does not cover routing or digit analysis aspects of the following topics: traffic management (see ITU-T Q.823 16); call-control; broadband; supplementary services;2 ITU-T Q.826 (02/2000) IN (Intelligent Network); customer administration; other services of which the
48、 definition is still under study (e.g. tariff management); PABX (Private Automatic Branch Exchange) as exchanges or as termination points ofsubscriber lines (because this is covered by customer administration); centrex implementations; mobility issues like cellular and personnel mobility;neither the
