Connexstar Digital Phone
Spacenet’s carrier-class Digital Phone service enables customers to make clear digital telephone calls, in addition to receiving business class Internet access, and real-time video over the same high-performance satellite link. Unlike traditional VoIP based services that leverage the open public Internet to provide inexpensive long distance calls, Connexstar Digital Phone, is a carrier class service that is directly connected to the public switched telephone network (PSTN) and provides toll quality calls and satellite phone lines that are FCC 911 compliant. Voice and data channels are completely separated, actually operating on different frequency channels, to ensure a high Quality of Service for mission critical applications like emergency response, oilfield operations, or business continuity. In addition, Digital Phone supports analog plain paper fax services as well as a variety of IP-based devices.
The service is available as an option with Spacenet's Connexstar Performance Series, Enhanced Services and select versions of the Connexstar Broadband Series satellite communications services.
How Connexstar Digital Phone Works
Voice transmissions are sent from the site up to the satellite and then back down to Spacenet’s teleport facility, through a “Voice Dedicate Access” channel. From there, the transmissions are sent directly to the PSTN through the telco central office. For fixed sites, specialized systems are utilized to provide automatic call routing to emergency service providers. For mobile sites, Spacenet provides 9-1-1 services powered by Intrado via a live emergency call relay center that’s staffed 24x7x365.
