FXO (Foreign Exchange Office) ports are used to connect your fax gateway to a traditional PSTN line, enabling communication with external phone lines. Choosing the right number of FXO ports depends on your need to interface with the PSTN. Typically, gateways like the Patton SmartNode 4141 4 FXO Analog Gateway offer 4 FXO ports, providing flexibility for small to medium-sized businesses that require multiple PSTN connections. This flexibility ensures that the gateway can handle multiple simultaneous calls or faxes.
