What it is Filled

A telecommunication circuit, usually a pair of copper wires or an equivalent connection, linking a subscriber to the telephone network, including landlines, private lines between two points and digital replacements over fibre or broadband.

Why it exists Filled

Let an agent handle telephone lines by type, provider, faults, migration to digital services, emergency calling and accessibility.

Distinguishing features Filled

  • Fixed connection to the network
  • Copper, fibre or digital voice
  • Assigned a number
  • Being migrated to IP in many countries

What robots and AI may and may not do Filled

Must not

  • Disconnect or transfer a line without the subscriber's authority.
  • Leave a vulnerable person without working emergency calling during a migration.
  • Intercept or record calls on a line without lawful authority.
  • Make scam or nuisance calls or help anyone do so.

Only with a human decision

  • Disconnecting or migrating a line used by a telecare alarm.

May

  • Report the status of a telephone line for its subscriber and explain migration to digital lines.
  • Check that telecare alarms and emergency calling still work after a line change.

Moral aspects Filled

  • Older and disabled people rely on landlines for alarms and emergencies.
  • Calls are private communications protected by law.

Who is affected

  • Subscribers
  • Telecare users and their carers
  • People receiving scam calls

Owners Filled
