The SPA-2102 features two POTS (Plain Old Telephone Service) ports for connection to existing analog telephones, fax machines, PBX and key system communication platforms. The SPA-2102 includes an Ethernet interface for connecting to a home or office PC (LAN) as well as an Ethernet connection to the broadband modem or router (WAN).

Each SPA-2102 service line can be independently configured via software controlled by the service provider and/or the end user.

Installed by the end user and remotely provisioned, configured and maintained by the service provider, each SPA-2102 converts voice traffic into data packets for transmission over an IP network. Upstream voice traffic can take priority over less time sensitive data traffic to provide quality of service (QoS) treatment to VoIP phone calls.

Stylish and compact in design, the SPA-2102 can be used in consumer and business IP telephony service offerings including full-featured IP Centrex. The SPA-2102 delivers clear sounding voice and reliable fax calling through its implementation of internationally recognized standards for voice and data networking.
