A new public network (NPN), in a historical telecommunications reference, is a proposed packet-based network that brings together the public switched telephone network (PSTN) and Internet technologies to carry voice, video, and data. It is a concept, not an established name for one particular network currently in service.
What does “new public network” mean?
The term describes a convergence of the PSTN and the Internet, or Internet-based technologies. The intended result is a multiservice, packet-oriented network that can handle different kinds of communication rather than a telephone network devoted mainly to traditional voice calls. The definition appears in the technical reference Linktionary’s NPN entry.
The phrase is sometimes paired there with “next-generation network.” That usage describes an architectural direction: combining the Internet’s distributed, open approach with telephone-network goals for service quality and availability. It should not be read as a guarantee that an ordinary public network provides a particular quality of service.

The contrast is about design goals and service scope, not a claim that every present-day network fits neatly into one category.
#1 Best Overall
| Aspect | Traditional PSTN | Internet model | New public network concept |
|---|---|---|---|
| Network approach | Traditionally circuit-oriented, using time-division multiplexing | Packet-based and distributed | Packet-oriented, drawing on Internet-based technologies |
| Services | Primarily telephony | Supports many kinds of data communication | Designed to carry voice, video, and data |
| Service intelligence | Historically more centralized and carrier-controlled | Distributed across the network and capable edge devices | Envisions more service creation and capability at the edge |
| Service objectives | Telephone-network service quality and availability goals | Often associated with best-effort delivery | Aims to combine an open, distributed model with managed quality-of-service and availability mechanisms |
These are broad distinctions in the concept’s description. They do not establish measured performance levels, universal guarantees, or a direct comparison of current networks.
Is NPN a current formal standard or a specific deployed network?
The available term-specific definition is historical and conceptual. It does not establish NPN as a current formal standards term or as the official name of one deployed network. A related 2002 patent application uses “New Public Communications Network” for a layered voice-and-data architecture with application, call-control, and transport or infrastructure layers; that is an example of related usage, not proof of a single industry-wide definition. See US20020191590A1.

Context matters. An EU directive uses the phrase “new public network termination points” in a historical regulatory provision concerning user access and publication of physical endpoint characteristics. That wording concerns network access points; it does not define the converged NPN architecture described above. The provision appears in Commission Directive 88/301/EEC.
