DSC stood originally for Digital Switch Corporation, and they did make
a switch. I know they were fairly big in the large PBX area, and
possibly in toll tandems, but I don't recall whether they made a local
switch. I would be somewhat surprised if they never did.

I think they achieved their greatest fame for making STPs, where they
became the dominant supplier for some time.
