[TUHS] Reaction to the 3B2 at Bell Labs

[Skip Tavakkolian]

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.
