Network number meaning

What does Network number mean?
In legal and telecoms practice, a network number is the underlying Calling Line Identification (CLI) applied by the originating communications provider to a call. It uniquely identifies the line or endpoint from which the call originated and is used for call routing, charging, tracing and fraud prevention. In many cases it is the same as the subscriber’s telephone (directory) number, but it may differ from the presentation number shown to the called party (for example, where a business displays a main switchboard number or the caller withholds display). The network number is not usually visible to the recipient, but appears in call data records (CDRs) and in disclosures from operators. In the UK, the concept is defined and regulated in Ofcom’s General Conditions on CLI facilities; in Ireland, ComReg’s numbering and CLI rules adopt equivalent principles. Usage is broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland. The network number is practically significant for evidence in disputes and harassment/fraud cases, disclosure requests to communications providers, number portability and billing issues, and compliance with PECR/marketing rules concerning valid, diallable caller identification.

Rights of Way Improvement Plans under the Countryside and Rights of Way Act 2000: duties of local highway authorities, review procedures and impact (England and Wales)

Rights of way strategy formulation In 1987, the Countryside Commission formally set a national objective for Rights of Way. The intention behind this target was that, by 2000, every right of way would be legally defined, suitably maintained, and clearly publicised. Subsequent surveys in 1988 indicated that the likelihood of completing a two‑mile walk was no better than one in three. Although the national aim was widely supported, it rapidly became apparent that a government‑sponsored strategic framework, preferably tied to funding mechanisms, was necessary to be put in place. In response, the Countryside Commission introduced the ‘Milestones Approach’ and required authorities to adopt it if they wished to draw on available grant‑aid funding schemes. Under this approach, authorities had to prepare a strategy document (a ‘Milestones Statement’) setting out a clear sequence of milestones (benchmarks) for achieving each of the national target areas: ‘legally defined’, ‘properly maintained’, and ‘well publicised’. This strategic model, coupled with funding opportunities, brought a marked increase in resources for rights of way management, with...
