As used here, telecommunication services include: voice telephony, multimedia and data, to name a few areas. The network requirements also include mobility-, Internet- and broadband-related aspects that were not yet covered by the preceding EG 201 722 [3] which address the first set of access requirements that Service Providers (SPs) have in delivering services over one or more Public Telecommunications Networks (PTNs), primarily fixed PTNs, A companion document, EG 201 807 [4] addresses network operators' requirements for the delivery of service provider access.

The scope of the present document is to describe generic functional requirements regarding the service provider access (SPA). The priority of each requirement is based on the need perceived from the service provider's viewpoint. To fulfil these requirements, appropriate protocols may have to be enhanced or developed based on information flows and taking into account network integrity considerations expressed in the present document.

Clause 4 contains introductory text describing the background and motivations of the second set of requirements of a SPA. Clause 5 contains a summary of requirements regarding the Service Provider Access Interface (SPAI) and a framework that helps the reader to get an overview. Clause 6 contains a description of the requirements involving Circuit-Related (CR) and Non-Circuit Related (NCR) aspects of the SPAI.

The present document relates to the role of the SP and the role of the Public Network Operator (PNO), with the realization that market players may act in multiple roles. This is in alignment with the current EC directives.

Service interaction aspects are outside the scope of the present document.
