FXS (Foreign Exchange Subscriber) and FXO (Foreign Exchange Office) are two types of ports used in telephony systems to connect analog devices, such as phones and fax machines, to a digital network.
An FXS port is used to connect an analog device, such as a phone or fax machine, to a digital network. It provides power to the device and allows it to make and receive calls over the network.
An FXO port, on the other hand, is used to connect a digital network to an analog device. It allows the analog device to make and receive calls through the digital network.
In general, FXS ports are found on devices that connect analog devices to a digital network, such as ATAs (Analog Telephone Adapters) and PBX (Private Branch Exchange) systems. FXO ports are found on devices that connect a digital network to analog devices, such as telephone exchanges and PBX systems.
