AFAIK, DS3 cards are special network cards for DSL ISP's/telecom coorperations.
They are used in wat we call "wijkcentrales" or co-location facilities so several home users or businesses can internet.
That is, 1 DS3 card can have more then 10 connections (28 ?) all with their own IP adresses or give a home user a IP adress.... Let's just call it an overblown router/switch..
I can be wrong tho..
Don't know the relevance to Amiga's, but hell, imagine, no internet access for a few hours ?
