You had to have two channels with ISDN so 128 kbps plus 16 kbps for
signalling = 144 kb

technically, yes. Commercially, no. You could buy a single channel.

For more than two channels they tended to install a fibre that would do
2Mbps.

At one time this was a free installation, so many of our customers did
that, then cancelled their ISDN and ordered a leased line based on
pre-existant fibre...saving themselves several thousand installation.

God what we have now,we would have killed for back then.
