AT&T Corp’s Largo, Florida-based AT&T Paradyne unit is collaborating with services and teleconferencing bridge providers to explore new ways to deliver simultaneous speech and data in network-based services using AT&T’s VoiceSpan technology, which splits the line into two virtual channels. MultiLink Inc, ConferTech International Inc, Teleconferencing Technologies Inc and SpectraFAX Corp plan VoiceSpan-enabled audiographic conferencing, VoiceSpan-enhanced fax-on-demand services, and interactive services for small businesses and home users of personal computers, telephones and facsimile machines. And with Radish Communications Systems Inc, Boulder, Colorado it has agreed on development of compatible technology linking VoiceSpan and Radish’s VoiceView, which VoiceView provides alternating voice-and-data communications using the full bandwidth.
