When BT say 'MSN' they mean batches of ten subscriber numbers, which they
offer with their 'normal' ISDN2e setup.
All incoming calls are announced down the ISDN line along with the telephone
number that they're destined for. All the ISDN equipment that you plug in has
to decide which calls to respond to, so it has to be given 'its' telephone
number. That is what's meant by 'MSN' in the i4l and Teles 2AB context.
It looks like the Home Highway installation comes with a digital-analogue
converter - and three telephone numbers. Their box will respond to two of those
numbers, and give you two analogue ports, one for each number. You have the
third number available for use with real ISDN equipment.
I don't know if it's possible to disable the analogue ports, and leave those
numbers free to be answered by other digital equipment.
However, if you just want one (or two) numbers for normal analogue phone/fax,
and a single number for digital incoming calls, it should be fine.
For each piece of equipment, set the 'MSN' to the full telephone number that
you want it to respond to, without the leading zero. So if your telephone
number is 01223 810302, you'd use an MSN of "1223810302"

You've listed four devices, and you only have three telephone numbers. But
that's not necessarily a problem - calls also have a 'service indicator' which
can be used to distinguish between analogue and digital calls. So you can have
two different devices on the same telephone number - one answering voice
calls, and the other answering data connexions.
