2316.0. "What is 90+ Backplane?" by MIMS::WELLONS_T () Thu May 25 1995 16:12

    What does the information in the new Network products guide mean under 
    decrepeater 90ts on page 2-20 it says:
    
    Backplane Thinwire and one flex Channel Ethernet
    on 90+ Backplane.
    
    What is a 90+ Backplane?
    Also can all ten connections be used on the DECrepeater 90ts -AA 
    at the same time? Thinwire, AUI, 8 UTPs?

    The 90+ Backplane is the backplane used by 90 modules (and 900 modules) in
    a DEChub 900. Its the upper 48 pin backplane. 
    
    You can only use 9 ports on the DECrepeater 90TS. The Thinwire and AUI
    connections cannot be used at the same time.

    The 90+ backplane is/was a project(s) to make a 90 hub that had 10B2 and a
    flex channel.  The top backplane in the 900 hub is more commonaly
    called the Secretariat.
    
    also, the thinwire and AUI port on the 90TS is only available when it
    is standalone.
