A Broadband Switching Experiment
01 January 1988
A broadband switching experiment was presented at the ISS '87 and Telecom '87 conferences in Phoenix, Arizona, and Geneva, Switzerland, respectively and at the March, 1988 Fair in Hanover, West Germany. This experiment was significant in that it illustrated techniques for switching broadband signals with a wide range of frequencies, formats, and ultimate purposes. In particular, simultaneous switching (within the same switch fabric) of 30 MHz PFM, 45 Mbps PCM, and 140 Mbps PCM was demonstrated. These signals carried full-motion, full-color NTSC video for desk-to-desk video teleconferencing, off-the air broadcast video programming, and surveillance camera video.
