The hardware support was 2B+D but you could definitely just use a single B. 56k vs 64k depended on where you where is the world and which style of ISDN the telco offered. -- Mark Andrews

I didn't think one could get a single 'B' channel over ISDN ... but I could be mistaken.
In my early ISP days, ISDN was 2 x 64k (full-rate) 'B' channels and a 16k 'D' channel for signaling.

Thanks Jared, When I reminisce with my boss he reminds me that this telco/ISP here initially started with a 56kbps internet uplink , lol
Point of History:
When we, The World, first began allowing the general public onto the internet in October 1989 we actually had a (mildly shared*) T1 (1.544mbps) UUNET link. So not so bad for the time. Dial-up customers shared a handful of 2400bps modems, we still have them.
* It was also fanned out of our office to a handful of Boston-area customers who had 56kbps or 9600bps leased lines, not many.
