Linksys SPA3102 - Local Access Number Line

The SPA3102 supports one RJ-11 POTS (Plain Old Telephone Service) FXS port to connect an existing analog phone or fax machine. The SPA3102 also supports one PSTN FXO port to connect to a Telco or PBX circuit. The SPA3102 includes 2 100BaseT 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 SPA3102 FXS and FXO lines can be independently configured 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 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.



Log into your control panel and click on the Local Access Number Setup button to create a calling card pin for the virtual number you will be configuring on the PSTN line of this device.

Once this has been setup, continue to step two.

Connect one Ethernet cable from your SPA3102’s ETHERNET port to the Ethernet port on your computer.

*PLEASE NOTE* Do not connect any other cables to the SPA3102 during initial configuration. (Cable/DSL/Router or Analog phone cables)  If you connect anything other than this one cable, you will not be able to log into the device.
