What set of protocols is it based on?

The last time I looked at PictureTel (a few years ago) they were using ISDN
and had no Internet-based videoconferencing - it was all point-to-point using
ISDN phone numbers. Some of their larger systems multiplexed three ISDN lines
to get up to 384K bandwidth.
