welcome to the world of dial-on-demand. 99% of decient routers will do this
on an ISDN connection :)

Try looking at the SNMP (Simple Network Management Protocol - NOT SMTP!!! it
has nothing to do with mail!) interface on the Cisco (assuming its plugged
into the ISDN modem), or on the modem if it has a network interface. That
should tell if you its up or not. If you have a [u|li]nux box around, there
are SNMP tools around, if you are on windows, well, there is an RFC for SNMP
somewhere, and the components in Indy may support it.....
Infact: <fires up delphi 6> it does not out of the box, but its fairly
simple and based on UDP AFAIK. You will need to hit either the modem maker
or cisco for the MIB (Management Info Block - IDL for SNMP) for the device
tho.
