FXO - Foreign Exchange Office

In telecommunications, a Foreign Exchange Office, or FXO, is a telephone signaling interface that receives POTS, or "plain old telephone service". It generates the on-hook and off-hook indicators used to signal a loop closure at the FXS's end of the circuit. Analog telephone handsets, fax machines and (analogue) modems are FXO devices, though the term is rarely used except in connection with Foreign exchange service (FX). FXO interfaces are also available for computers and networking equipment, to allow these to interact directly with POTS systems. These are commonly found in devices acting as gateways between Voice over Internet Protocol (VoIP) systems and the public switched telephone network (PSTN).

FXS - Foreign exchange station

In telephony, a Foreign Exchange Station, or FXS, is a telephone interface which provides battery power, sends dialtone, and generates ringing voltage. A standard telephone plugs into such an interface to receive telephone service. Strictly speaking, a telephone exchange is an example of an FXS, as is the telephone plug on the wall, though the term is rarely applied except in connection with foreign exchange service.

DID - Direct Inward Dialing

Direct Inward Dialing (DID), also called Direct Dial-In (DDI) in Europe, is a feature offered by telephone companies for use with their customers' PBX systems, whereby the telephone company (telco) allocates a range of numbers all connected to their customer's PBX. As calls are presented to the PBX, the number that the caller dialed is also given, so the PBX can route the call to the desired person or bureau within the organization.
