Scope and field of application
Network operations, administration and maintenance (OA and M) applications need to be able to operate over a variety of networks, including public data networks.
This Recommendation describes the interworking between CCSN and packet switched public data networks (PSPDNs), which may be needed for the transmission of operational information between Administrations, as a means of data transmission between operational centres and/or terminals for those Administrations.
It should be noted that, when dealing with OA and M protocols, a great confusion may appear between:
- the network which is used to convey the OA and M information (e.g. CCSN or PDN in Figure 1/X.326 above);
- the network which is controlled by the CCSN, with the support of the OA and M applications.
It may furthermore happen that the controlled network interwork with a PDN, as illustrated in the following Figure 2/X.326. Such an interworking is not considered as interworking between CCSN and PDN; consequently it is not described in the present Recommendation.
