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.

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,
