3B20D's that were used for cellular switches used DMERT.
I worked for McCaw Cellular (Cellular One) in mid-late 80's. They had
several AT&T switches. The monitoring and management system at the NOC in
Seattle was developed by BL (I think it was Indian Hill). It was called
MFOS and ran on 3B2-400s and used Datakits for networking.

when the first 3B20 arrived. the first order of business? running off to
the
local Sears store to buy 4 car batteries so it
could power up. what a
hoot!
So what did the 3B20s run when they were being used in a Telco? Unix?
Or some other specialized OS?
Or was said 3B20 a prototype before they'd been deployed to the Telcos?
Thanks,
