2 Ports FXS Analog Telephone Adapter, 2 Ethernet Ports LAN-WAN

Inexpensive, easy-to-install and simple-to-use, the SPA-2102 connects standard telephones and fax machines to IP-based data networks. IP telephony service providers and enterprise users can offer traditional and enhanced communication services via the customers’ broadband connection to the Internet or Local Area Network (LAN).

FXS stands for Foreign eXchange Station. FXS ports connect your existing analog phones and analog fax machines to a digital PBX system. An FXS adapter makes use of your digital telephone system for connectivity to other stations internally or to external phone numbers.

With an FXS adapter - your business does not need to replace your existing analog phones, fax machines, credit card machines simply because you're upgrading to a digital PBX or going to deploy VOIP.

FXO stands for Foreign eXchange Office. FXO ports connect the Plain Old Telephone Service (POTS) or the telephone company’s line to the PBX system. FXO ports connect your computer to Public Switched Telephone Network (PSTN) telephone lines. An FXO adapter makes use of your telephone company’s subscription line to provide telephony functions to your computer – this is also a cheaper alternative to expensive VoIP systems.

FXO modules receive the signal coming from your POTS and transmit it to your network of IP telephones and VoIP applications.
