VPBX Home Gateway Design
VOCAL’s VPBX Home Gateway Reference Design details an example of an innovative Voice over IP-PBX product which uses HPNA and an Internet connection to meet all the telephony needs of a home or small office. It is composed of the VPBX Home Gateway Unit (VHGU) and the VPBX Extension Device (VED). The VHGU is the central controller, handling all networking and voice/telephony processing as HPNA connectivity to VED endpoints. The VEDs are minimal POTS interfaces that may be placed anywhere on the HPNA network. Calls are placed from the VEDs through the VHGU to external parties as appropriate for the type of call.
We have over 25 years of custom design and development experience in the telecommunications industry, our expertise and extensive customization support will result in the product you want at an unbeatable cost. Since VOCAL provides both the hardware design and a complete, optimized software solution, the result is a fully integrated, robust product which can be brought to market quickly.

Home Phoneline Networking Alliance (HPNA)
HPNA technology allows for new multimedia services such as IPTV and VoIP to be brought into the home without requiring new wiring. Existing phone lines and coax cables are used to provide high-speed data rates of up to 320 Mbps. This makes a wide range of home networking functionality available at low cost, such as whole-home IPTV, PVR, DVR, HD video, etc. Voice, video, and Internet access provided by fiber, DSL, wireless, and satellite sources can be easily distributed throughout the home or multiple-dwelling unit (MDU) using HPNA.
The HPNA-based VPBX system allows a homeowner to use any phone in the house to access their VoIP calls. Moreover, the VPBX permits seamless access to the original telephone company PSTN line and up to 4 different VoIP service providers. VOCAL’s Concurrent VoIP ™ technology allows one of these service providers to be MGCP-based while the others may be SIP-based. The VPBX system also supports station-to-station dialing and paging within the home environment.
