Voice-over-Internet Protocol (VoIP) Smart Node solutions .Foreign exchange Subscriber (FXS) and Foreign exchange Office (FXO).

Detailed Description The question what is the difference betweenFXS and FXO? is frequently asked by those deploying Patton Voice-over-InternetProtocol (VoIP) Smart Node solutions. Foreign exchange Subscriber (FXS) andForeign exchange Office (FXO) are the names of the two most common interfaces(ports or plugs) found in analog telephony environments. Analog telephony, also known as Plain Old Telephone Service (POTS), is the service the local phone company typically delivers to your home. Local phone companies deliver POTSfrom their Central Office (CO) to the subscriber's premises over a circuit consisting of two copper wires. To increase the distance over which the signal can be transmitted the two wires are twisted together, which also reduces electromagnetic interference. So these two-wire copper cables are commonly known as twisted pairs.
