scope:

The present document lists 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, e.g. public switched telecommunications networks (PSTNs) and Integrated Services Digital Networks (ISDNs). These requirements are intended to facilitate a non-discriminatory access to the PTNs. The present document does not fully take into account the network integrity, security, charging, and other related aspects from a PTNO's perspective. These aspects are defined in DEG/SPAN-061603. The present document and DEG/SPAN-061603, should not be considered separately for implementation.

The scope of the present document is to present 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. Service interaction aspects are outside the scope of the present document.

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 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 concerning the circuit-related (CR) aspects of the SPAI, and clause 7 contains the requirements regarding the non-circuit-related (NCR) aspects. Clause 8 contains information on the architectural view of the service provider access.

The present document relates to the role of the SP and the role of the public telecommunications network operator (PTNO), with the realization that market players may act in multiple roles. This is in alignment with the current European legislation, which specifies that all capabilities utilized by a significant market power (SMP) network operator's internal service provisional body, shall also be offered on equal terms to external entities.
