I have heard of two scenarios. 1 was used. probably with a PRI, European
standards Europe PRI = 30B + D and a BRI, they were able to establish a link
with the two D channels and send TCP keepalives. free 16k fixed connection.
not really practical for much. but hey it was free. Not that it mattered,
they were a telco.
It was also suggested that using two Cisco 1600's each with a BRI configured
for dial on demand, that one could initiate a call to the other over the D
channel to allow the router making the call to bring up the B channels on
remote router, initiating a call to the internet where the router could then
be access via IP.
I want to know if this is possible so I can better support a remote office
on dialup, when there are network issues.
Any ideas?
Thanks Damien
