In December 1987 issue of Data Communications there was a short note
stating that the 802.6 (MAN) committee had adopted QPSX (Queued Packed
and Synchronous Switch Dual-But) network topology over competing FDDI.
The note says that QSPX is a dual-fiber nonbranching bus looped into a
ring.

Can someone give pointers where to find more information about QPSX?
Is QPSX still a paper product or are there chips and implementations
available?  What will happen to FDDI - will it survive when Bell
companies and AT&T are backing QSPX?
