Plain Old Telephone Service (POTS)

The traditional function of telephone networks for voice communications. In most contexts, POTS is synonymous with the public switched telephone network (PSTN). POTS takes the lowest 4 kHz of bandwidth on twisted-pair wiring. Any service sharing a line with POTS must either use frequencies above POTS or convert POTS to digital and interleave with other data signals.
