FXS is always in connection with an FXO or Foreign eXchange Office, which is the plug on your phone or fax machine. A PBX can be installed between your FXO and FXS ports. A PBX, or a Private Branch Exchange functions as a server that can connect local calls between extensions, and outgoing-incoming calls to the local network.
Via the Internet, the PBX will be able to connect your analog phone system or a traditional PBX to a Voice over Internet Protocol server or to each other. The Voice over Internet Protocol, or VoIP is a protocol that directs transmission of voice data packets over the Internet.
An adapter is a device that can synchronize two or more technical devices. You will need to obtain one, more specifically an Analog Telephone Adapter (ATA). ATAs connect the analog and the digital telephone systems. In this case, if you would like to connect your traditional phone to the Internet. Through an ATA, direct communication comes to pass between an analog phone and a VoIP server. You don't even need to install any further programs.
Your FXS can only reach the highest capacity and so the most data with the best quality, if your server gives them to you. Ozeki Phone System XE will. Our customers are always satisfied with our next generation services.
