GeoPort Technology
Geoport is a hardware and software communications
architecture that has been optimized for computer-
telephony integration. It has three main attributes:
• It lets any GeoPort-compatible computer connect to any
telephone (analog or digital, public or private)
anywhere in the world.
• Once connected, it supports an arbitrary number of
independent data streams up to a total bandwidth of
2 MB/second.
• Unlike traditional asynchronous data communications
(such as AppleTalk), GeoPort also supports isochronous
data streams (such as real-time voice and video) and
provides the real-time application program interfaces
(APIs) necessary to hide the implementation details
from both the recipient and the sender.
