Dataphone is a registered trademark of AT&T
I saw the Dataphone label on all sorts of modems: SDLC, async, dialup and probably leased line as well.
Yup, lots of DS0 (and sub divided DS0s) and T1s. Not so many T3s as those we too expensive.
Long before those were common for this type of use, there was a big crop of leased-line subrate modems that bore the Dataphone moniker, from 9600 baud down to 1200, and possibly below that. These were for four-wire leased lines. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
