These definitions are to be used to develop a protocol-neutral information model. A network view and a network element view combined with the network view of an ATM-PON ar

The concept provides a protocol-neutral ME3 and thus permits developers to derive an implementation-specific MIB from any management protocol. The information model described herein is used on an interface between a Network Ma

The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure la

26、l of ATM-PON system at a Q interface at a reference point beyond an element management layer i. This Q interface is defined as the network view and the network element view combined with the network view (combined view). This Recommendation provides network view managed entities to support a protoco
27、l-neutral information model for ATM-PON. As a consequence, the managed entities and their properties will be used to develop a protocol-neutral information model. The model may then be used to develop specific MIBs which are appropriate for the management protocols. These managed entities are specif
28、ic to the ATM-PON system. Therefore, the suflfix “F“ is added to their names in order to distinguish them from generic managed entities. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recom

The OAN may include a number of ODNs connected to the same OLT. 3.2 optical distribution network (ODN): An ODN provides the optica

42、his Recommendation addresses the management functions of FSAN subnetworks across the Q interface. The operation systems manage FSAN network elements and their interface ports by means of managing OLT through the Q interface. FSAN network elements include OLT, ODN, ONU, NT and ONT i shown as Figure 1
43、. The ODN offers one or more optical paths between one OLT and one or more ONU/ONTs. ONU and NT are connected by ADSL or VDSL. OLT has a BICVBISSI port towards the core network, and ONT” has one or more UNI port(s) for the customers. The FSAN subnetwork is defined between BICVBISSI ports and UNI por
44、ts. The OLT manages ONU, NT andONT2. Figure UQ.834.2 - FSAN network elements and FSAN subnetworks The FSAN Element Management System (FSAN EMS) consists of E-OSF and includes a little N-OSF and S-OSF 3. It manages both FSAN network element and FSAN subnetwork shown in Figure 2. The Q interface speci
45、fies the network view and the combined view.

46、hitecture 4 ITU-T 4.834.2 (04/2001) 5.2 Approach to information modelling We have taken a black box approach on the two ends of the interface in order to make progress. The assumption of the approach is that as long as the model indicates the objects and attributes, albeit at a high level, it should
47、 be possible to arrive at a common specification of the Q interface. 5.3 This Recommendation adopts a combined view defined as the network element (NE) view combined with the network view in order to treat both FSAN network element and FSAN subnetwork. Some NE view managed entities, such as vpTTPF,
48、vpCTPF, VCTTPF and VCCTPF, point to and are pointed fiom the corresponding NW view managed entities, such as vpNetworkTTPF, vpNetworkCTPF, VcNetworkTTPF and vcNetworkCTPF, using NEAssignmentPtr in the combined view. NE view combined with NW view (Combined view) 6 Requirements The general requirement
49、s for the ATM-PON operation system are described in Appendix YQ.834.1 4, FSAN operations requirements. This Recommendation uses some of them. The number and letter written after the requirements refer to an associated item in Appendix YQ.834.1. The FSAN Element Management System shall be able to create the logical representations of the resources required to manage the network and services. All necessary network and service parameters shall be supplied in the appropriate request. (77 M) It shall be possible to create the logical resources in the FSAN Element
