Analogue lines are the most basic form of phone lines, having been in use for over 100 years. Analogue lines are a PSTN service rather than ISDN (Public Switched Telephone Network), and are still widely used for a variety of purposes such as alarm lines, an ADSL bearer line, PDQ machines, or just as a simple phone line – most residential lines are single analogue lines.
Key features of analogue lines include:
- Available as single Direct Exchange Lines (DELs) for use with alarm, PDQ, ADSL or Fax.
- Also available as Multi-Lines on one number for business use (no DDIs etc).
- Wide range of Special Services available such as Call Minder, Call Divert etc.
