Frank,
This is an easy one. Terminal Adapters are very inexpensive
compared to the equipment you have already purchased. I bought
two IBM 7845's for less than $30 a piece off of ebay. No
configuration required. Put them between your Cisco router and
the Teltone and you are all set.
I couldn't find any 7845's on ebay, but I did come across this
beauty. http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=374824305
Don't forget that the U reference point is strictly a point to point
connection, while the S/T reference point is a point-to-multipoint
connection. Thus you can connect two Cisco Routers (2503/2503) to
a single ISDN BRI on your Teltone, thus you could connect up to four
Cisco Routers w/ISDN to your single ISDN simulator. This could be
very useful for playing with Dialer Profiles assuming your Teltone
has a unique phone number for each of the SPIDS. I have never done
this, but it should technically be possible.
Good luck,
AQ
