The Cisco SPA3102 Phone Adapter with Router has the ability to connect standard telephones and fax machines to an IP-based data network, with the additional benefit of an integrated connection for legacy telephone network "hop-on, hop-off" applications. With SPA3102 you can extend the use of your broadband phone service by automatically routing local calls from mobile phones and landlines to voice over IP (VoIP) service providers and vice versa. If power is lost to the unit or Internet service is down, calls can be redirected to a traditional carrier via the FXO interface.
A user calling from a mobile phone or landline will be able to reduce and even eliminate international and long-distance telephone charges by first calling the Cisco SPA3102 via a local telephone number. The advanced authentication and call-routing intelligence programmed into the SPA3102 will route the call via the Internet to the end destination. In addition, when using a SPA3102 at the far end, VoIP calls placed to that location can be either answered or further processed and routed on as local calls to any legacy land line or mobile phone.
The Cisco SPA3102 supports one RJ-11 basic telephone FXS port to connect an existing analog phone or fax machine. It also supports one public switched telephone network (PSTN) FXO port to connect to a telephone company (Telco) or private branch exchange (PBX) circuit. The SPA3102 also includes two 100BASE-T RJ-45 Ethernet interfaces to connect to a home or office LAN, as well as an Ethernet connection to a broadband modem or router. The FXS and FXO lines can be configured independently via software controlled by the service provider or the end user.
Installed by the end user and remotely provisioned, configured, and maintained by the service provider, each Cisco SPA3102 converts voice traffic into data packets for transmission over an IP network. Compact in design, the SPA3102 can be used in consumer and business VoIP service offerings, including a full-featured IP Centrex environment. The SPA3102 uses international standards for voice and data networking for reliable voice and fax operation.
