Yes but, Costing of Multi-link PPP is wonderfully better.
Total cost is PER LINK is
Setup = two modems and two line installations @ $173???
Onoing $40/month (? what is business now per month) and worst case 1
call (25c/day)
Actually, the lines DO NOT have to be business lines.
No data charges, no time charges.
I serve WWW and email across a dial up link. The only people who have
trouble with the latency are spammers.

Yes, repeatedly over more than 10 years.

You will find that the ISDN link will bleed you dry unless you are
going to make a MOTZA each month.
Actually, badly tuned modems will perform badly, no matter what the
brand.
Two 33K modems will get close to 66K depending on lines, modem tuning
and EQL/?.
