Regarding the bandwidth discussion:
I recently set up a commercial video conferencing system which uses ISDN.I
found it very interesting that the lines from the Dmark (and for all I know
the lines to the Dmark) to the ISDN outlet in the wall were standard 2
conductor telephone wire. These two wires carried carried both "B" channels
and the "D" channel. The "B" channels being 64K each. This begins to make
sense in light of this discussion.
