, there are 4 connections, each of which may be hardwired, but more often uses a plug and socket:
telephone line to phone cable: The wall jack. This connection is the most standardized, and often regulated as the boundary between an individual's telephone and the phone network. (In many homes, though, the boundary between utility-owned and household-owned cable is a jack on an outer wall; all wall jacks in the home are part of the household's internal wiring.)
phone cable to phone base: This and further connections is generally not regulated, but instead has de facto standards. It is often 6P4C, which is often RJ11, but may be proprietary or hardwired.
phone base to handset cable:
handset cable to handset: The last two (the handset cable) has a de facto standard of a 4P4C connector with straight through cable.

Some of these may be absent:
  • Wired telephones may not have a separate base and handset,
  • the defining characteristic of wireless telephones is that they do not have a handset cable, and
  • the defining characteristic of mobile telephones is that they do not have a phone cable.

Wiring

A standard specifies both a physical connector and how it is wired. Sometimes the same connector is used by different countries but wired in different ways.

For example, telephone cables in the UK

 at the telephone end: this latter may be wired as per the RJ11 standard (with pins 3 and 4), or it may be wired with pins 2 and 5, as a straight through cable from the BT plug (which uses pins 2 and 5 for the line, unlike RJ11, which uses pins 3 and 4). Thus cables are not in general compatible between different phones, as the phone base may have a socket with pins 2 and 5 (requiring a straight through cable), or have an RJ11 socket (requiring a crossover cable

s are used, the "latch release" of the connector should be on the "ridge" side of flat phone wire in order to maintain polarity.

Though four wires are typically used in U.S. phone cabling, only two are necessary for telecommunication. In the event that a second line need be added, the other two are present.

Compatibility

Different telephone connections are generally compatible with the use of an adapter: the physical connector and its wiring is the primary incompatibility.
