ETSI 5 ETSI TS 1 O1 674-2 V1.l.l (2000-05) 1 Scope The present document specifies a TMN X-interface for the transfer of network management inform

17、ation for interoperable ATM services. This interface, for which hereafter in the present document the term “X.easi interface“ is used, allows for the management of interconnected ATM networks in order to provide ATM based services across network boundaries. The present document describes the X.easi

18、interface together with essential supporting administrative processes including: A description of the network architecture and related aspects including management processes; ATM network management requirements and capabilities of the X.easi interface; Testing issues. In addition, two informative an

19、nexes are provided to describe (A) an “ATM interconnect services and processes model“, which provides an example of processes associated with the use of the User and Control network to network interface specification (“NNI.easi“) specified in ETSI TS 101 674-1 2 and the X.easi interface; (B) an exam

20、ple of a reasonable “Business Model“ for the roles which organizations might play in the framework of providing ATM interconnection services. 2 References The following documents contain provisions that, through reference in the text, constitute provisions of the present document.

ATM Access Point: means by which a subnetwork offers external interfaces to other subnetworks. It is associated with an end point

38、of an IPPL ATM Gateway: represents an ATM access point in one subnetwork, which is associated with an ATM access point in another subnetwork for the purpose of topological interconnection connection: ATM cell transport entity, which is capable of transferring information transparently between connec

39、tion points. A connection defines the association between the connection points and the connection points delimit the connection Connection Admission Control (CAC): set of actions taken by the network at the connection set up phase (or during connection re-negotiation phase) in order to establish wh

40、ether a virtual channel connection or a virtual path connection can be accepted or rejected Data Communications Network (DCN): dedicated network used to interconnect operators network management platforms supporting automated X.easi interface processes. (The DCN may be configured as a “closed user g

41、roup“ among these operators management platforms) Inter-PNO Physical Link (LPPL): represents a physical link that offers bi-directional transmission capabilities and connects two subnetworks. Each InterPNOPhysicalLink is terminated by two ATM Access Points, which are in charge of notifying failures

42、related to the link or to the access point itself. An IPPL can be realized by any transmission capability (SDH, PDH etc.) link: “topological component“ which describes the fixed relationship between a “sub-network“ and another “sub-network“ or “access group“. It is defined by an access point on one

43、subnetwork, which is associated with an access point on another subnetwork NNLeasi interface: network to network interface in the User and Control Planes, specified in ETSI TS 101 674-1 2 subnetwork “topological component“ of a network used to effect routing and management. subnetwork connection: su

44、bnetwork connection is capable of transferring information transparently across a subnetwork. It is delimited by connection termination points at the boundary of the subnetwork and represents the association between these connection points. It can be a VP or a VC connection Trouble Ticket: report us

45、ed to exchange information about the resolution of faults, degradations or provisioning problems between operators. Refer also to ITU-T Recommendation X.790 18 for a definition of Trouble Management and Trouble Reporting Virtual Channel Connection (VCC): ATM cell transport entity formed by a series

46、of connections between the end- points. A Virtual Channel Connection is contained in a Virtual Path Connection.
