Product Overview

The Cisco ® SPA3102 Phone Adapter with Router (Figure 1) features 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. SPA3102 users will be able to extend the use of their 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.

Features

Toll-quality voice and carrier-grade feature support: The Cisco SPA3102 delivers clear, high-quality voice communication in diverse network conditions. Excellent voice quality in a demanding IP network is achieved via the advanced implementation of standard voice coding algorithms. The SPA3102 is interoperable with common telephony equipment such as voicemail, fax, PBX, and interactive voice response systems.
Large-scale deployment and management: The Cisco SPA3102 enables service providers to provide customized VoIP services to their subscribers. It can be remotely provisioned and supports dynamic, in-service software upgrades. A highly secure profile upload saves providers the time and expense of managing and preconfiguring or reconfiguring customer premises equipment (CPE).
Ironclad security: Cisco understands that security for end users and service providers is a fundamental requirement for a solid, carrier-grade telephony service. The Cisco SPA3102 supports highly secure, standard encryption-based methods for communication, provisioning, and servicing.
