Narrowband Internet termination meaning

A wholesale telecommunications service that carries dial‑up (narrowband) Internet traffic from an end user’s PSTN or ISDN line to the internet service provider’s point of presence, typically over the public switched telephone network. In practice, it describes the termination element of an Internet access call (the handover and delivery to the ISP), distinct from call origination from the end user. The term is descriptive rather than a statutory definition, but is used in Ofcom and ComReg market reviews, determinations and reference offers under the electronic communications regulatory framework. Usage is broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland. Key legal features include interconnection and conveyance arrangements, applicable wholesale charges, and (historically) significant market power remedies such as price control and access obligations. It often involves specific routing to ISP equipment and, in legacy contracts, dial‑up access number ranges. Although largely superseded by broadband/IP services, narrowband Internet termination still arises in legacy interconnect agreements, dispute resolution, and service cessation during the PSTN switch‑off. Practitioners should check current regulatory conditions, migration obligations, and contractual change procedures when addressing charges, service continuity or decommissioning.
