ISDN Primary Rate Interface Service is 23 ISDN B channels, and a single
ISDN D channel coming in over a single T1. The original post was meant to
be a slam against a poster who suggested using ISDN, the response was
"ISDN is *NOT* upgradable over 128K"... I mearly suggest that "ISDN" doesn't
really have any limit to it's upgradability, or at least, surely not 128K...
Now whether it is a viable solution for an Internet up-link is another
topic I'd be happy to discuss.. We have several companies that think the
savings of using ISDN vs. FT1 is well worth the minor inconviences that
ISDN has...
