Plain Old Telephone Service
(POTS)
Plain old telephone service, or POTS, are the
services available from analogue telephones prior to the introduction
of electronic telephone exchanges into the public switched telephone
network. These services have been available almost since the
introduction of the telephone system in the late 19th century.
The system was originally known as the Post Office Telephone
Service or Post Office Telephone System in many countries.
The term was dropped as telephone services were removed from the
control of national post offices. POTS services
include:
bi-directional, or duplex, voice path with
limited frequency range of 300 to 3400 Hz dial tone and ringing signals subscriber dialing operator services, such as directory assistance
and long distance and conference calling assistance
With the advent of electronic telephone exchanges and
computerization during the 1970s and 1980s, a raft of new network
services became available. These had been termed PANS for
pretty advanced network (or new) services by some in
the industry, although that term has never really caught on. The
services offered include:
and a number of other similar services.
The new services were made possible by the introduction of the support
network for the ISDN as well as raised consumer expectations from
services offered on mobile telephones.
