15、which span several administrative ATM domains. These requirements are satisfied by the use of a standardized interface (the “X-interface“) between Operation Systems (0%) belonging to different Public Network Operators (PNOs). The present document describes the X-interface VP alarm management area co
16、vering the following aspects: - the Management Services (MS) and Management Functions (MF) needed that provide the necessary alarm messages for faults detected within ATM Connections which span several administrative domains; the management information crossing the X-interface. This management infor
17、mation specification uses the Guidelines for the Defmition of Managed Objects (GDMO) formalism, described in ITU-T Recommendation X.722 121. - The present document has been named as “ATM VP alarm management“ because it is expected to be part of a comprehensive fault management standard for ATM VP an
18、d Virtual Channels (VCs) in due course. As such it is self-sufficient for the defined scope of reporting faults on, and recovery procedures for, VPs across the X-interface. 2 Normative refe re nces References may be made to: specific versions of publications (identified by date of publication, editi

L11J 3 3.1 Definit ions and abbreviations Definitions For the purposes of the present document, the foilowing definitions apply: (Some definitions depend on the future acceptance of the “cascadedlmix
26、ed mode“ as described in EN 300 820-1 i. This dependence is already taken into account in these definitions). access point: It is defined in ITU-T Recommendation G.805 131. A Public Network Operator (A PNO): The A PNO is the PNO whose subnet is connected to the A user, the user where the overall VP-
27、connection starts. The A PNO can be the initiating one, but this is not always the case. If it is the initiating PNO it is the root of the X-interface tree. If not, it is the most left leaf (as indicated in figure 1). if, in fuhire the “cascaded“ mode should be accepted as defined in EN 300 820-1 l,
28、 and if the A PNO also acts as initiating PNO, then the A PNO is the consumer of the other PNOs parts of the VP connection. cascade organization: It is described in EN 300 820-1 i. The impact of this organization on the model is for further study. connection: A “transport entity“ which is capable of
29、 transferring information transparently between “connection points“. A “connection“ defiies the association between the “connection points“ and the “connection points“ delimit the “connection“. consumer and provider roles of a PNO: With respect to a particular VP, a PNO acts as a consumer if it has
30、delegated the management of a VP subnetwork connection plus the outgoing link connection (both shall be part of the connection) to another PNO (that acts as a provider). If, in future, the “cascaded/mixed“ mode should be accepted (EN 300 820-1 i), a PNO can have both roles at once, if it is providin
31、g part of the VP (acting as a provider), and at the same time asks another PNO to provide a part of the connection (acting as a consumer). destination PNO: Z PNO (mis term was used in older versions of the specification). initiating Network Operator (PNO): The initiating PNO is the PNO requesting a
32、particular ATM connection starting in the A subnetwork and ending in the Z subnetwork; it controls the overall VP connection. Inter PNO Physical Link (IPPL): It represents a physical link that offers bi-directional transmission capabilities and connects two pnoVpSubnetworks. Each InterPNOPhysicaiLin
33、k is terminated by two pnoNWAtmAccessPoints which are in charge of emitting failures related to the link or to the access point itself. An IPPL can be realized by any transmission capability (SDH, PDH etc.). There is no explicit managed object defined in the X-interface that represents this resource
34、. Information about IPPLs is included in the interPNOTopologicalSubnetworkPair object, EN 300 820-1 i. Link connection: A “transport entity“ provided by the “client/server“ association. It is formed by a near-end “adaptation“ function, a server “trail“ and a far-end “adaptation“ function between “co
35、nnection points“. It can be configured as part of the “trail management process“ in the associated server layer. Link: A “topological component“ which describes the fixed relationship between a “sub-network“ and another “sub-network“ or “access group“. mixture organization: It is described in EN 300
36、 820-1 i. The impact of this organization on the X-interface model is for further study. network connection: A “transport entity“ formed by the series of “connections“ between “termination connection points“. ETSI STD-ETSI EN 300 820-2-ENGL 1998 m 3400855 03153b7 582 7 EN 300 820-2 V1.2.3 (199807) o
37、riginating PNO: An A PNO when it is also the initiating PNO. (This term was used in older versions of the specification). Public Network Operator (PNO): An operator that manages an administrative ATM domain. The term PNO is used in the present document to be in alignment with EN 300 820-1 i. pnoVpSu
38、bnetwork: A subnetwork (according to 1TU-T Recommendation G.805 131) is a topological component used for carrying ATM cells. PnoVpSubnetworks are delineated by termination points, modelled by VpCTps contained in NWATMAccesspoints, and they are used for setting up pnoVpSubnetworkConnections. NOTE: In
39、 principle (cf. to 1-ETS 300 653) one subnetwork can consist of several subcomponents: subnetworks and connections between subnetworks (generally called link connections). But this capability is not supported in Xcoop. Usually one pnoVpSubnetwork represents an ATM network belonging to the domain one
40、 network operator. protection switching: Automatic switching to pre-assigned spare capacity in network resources, consequent on reaction to receipt of an alarm signal by a network management system. (In the context of the present document, this is internal to a PNO). recovery: Recovery is a procedur
41、e performed by a PNO which makes use of spare capacity in the subnetwork or inter-pno physical links belonging to this PNO. It follows after an alarm signai from a fault in the PNOs network resources. star organization: It is described in EN 300 820-1 i J. It is the organizational form that is used
42、in this specification. sub-network connection: A “transport entity“ formed by a “connection“ across a “sub-network between “connection points“. It can be configured as part of the “trail management process“ as defined in IT-T Recommendation G.805 131. subnetwork: A “topological component“ used to ef
43、fect routing and management. It describes the potential for “sub-network connections“ across the “sub-network“. It can be partitioned into interconnected “sub-networks“ and “links“. Each “ sub-network“ in turn can be partitioned into smaller “sub-networks “ and “links“ and so on. A “sub-network may
44、be contained within one physical node. termination connection point: It is defined in IT-T Recommendation G.805 131. trail: It is defined in IT-T Recommendation G.805 131. transit PNO: A transit PNO is a PNO using its own subnetwork to perform its required transit part of VP connection. It has a pro
45、vider role and corresponds to a leaf in the X-interface tree, not being the Z side. In the “cascadedmixed approach“ case (EN 300 820-1 111). it can be both a provider (where it acts as a msit) and a consumer (where it effectively acts as an Initiating PNO). user: An end customer which is associated
46、with the reservation of a VP connection. VP subnetwork connection: A “transport entity“ which is capable of transferring information transparently between “connection points“ across a subnetwork or from a subnetwork access point to a user. X-interface tree: With respect to a particular VP, an X-inte
47、rface relationship exists between each provider PNO and its consumer PNO. Because each provider has exactly one consumer, the X-interface relations between all PNOs involved in the management of a particular VP form a tree, the X-interface relation tree. Note, that for a particular VP there can be s
48、everal possible X-interface relation trees; the actual tree is formed at VP Set-up. The root of the tree is the Initiating PNO; it uses (and via an X-interface controls) the PNOs (often transit PNOs), to which it is connected in the tree via its branches. The most right leaf of the tree is the Z PNO
49、. Figure 1 shows an example of an X-interface tree. X-interface: The management interface between two PNOs. In the “Responsibility Model“, which is described in ITU-T Recommendation M.3010 141, two Operations Systems Functions (= Managers ) that are located in different TMNs (= different PNOs), communicate over an X Reference Point. Z PNO: A Z PNO is a PNO whose subnet is connected to a user, where the overall VP connection ends. 8 Initiating PNO EN 300 820-2 V1.2.3 (1 998-07) Transit Transit PNO PNO Figure 1: Example of an X-interface tree
