Glossary


Access Bundling (AB): set of analogue or basic accesses grouped together for call processing or management purposes. The main line within the bundle, called the “Bundling Head Access”, bears the number that identifies the group; its number is the Isolated Bundle Designation Number (IBDN). Basic Access Bundling consists of at least two basic accesses at the same geographic address, it initially includes up to 6 (six) accesses, and can be extended to 8 (eight).

Access Identification System via Number (AISN): a service for pre-qualifying an order by identifying the owner of a line and the relevant technical information.

APNF: Association de la Portabilité des Numéros Fixes (fixed number portability association). Organisation that compiles and manages the reference database of fixed numbers that have been ported.

Area with Fibre: draft statute to be established in law that would be attributed to high quality FTTH plates (e.g. completeness of deployment, operational quality, etc.), and would trigger certain measures to speed up the migration from copper to fibre (helping with final connection, stopping new copper connections in buildings, rising cost of copper, etc.).

Asymmetric Digital Subscriber Line (ADSL): a technology that allows high-speed data transmission over the existing telephone network. It provides higher throughput downstream (towards the user) and lower throughput upstream (towards the DSLAM).
