[MLB-WIRELESS] Connecting nodes/clusters and expanding the mesh via Internet tunnels.

[Paul van den Bergen]

Hi all,

just hold on a second...  maybe I should clarify.  I don't know 
specifics about ADSL modems.  I do know how they work in general terms 
(point to point w/- the exchange then over the backbone network to the 
ISP). I am also familiar with FR and ATM and ISDN/BISDN setups, etc.

none of the answers so far have answered my question.  when an ADSL 
modem is set up it creates a channel (VNC on the ISP's VNP for ATM??) to 
the ISP.  it is still just a connection between two points, the ISP and 
the home user.  the fact that it goes over an ATM or FR network does not 
really matter.  Is there a physical reason I cannot (if telstra is 
cooperative, etc.) set up a connection between my ADSL modem and a 
friends on another exchange, presuming that the appropriate FR or ATM 
channel is established between the two exchanges?  Next question is what 
is required to get telstra to allow such a connection? cost and 
permission?  who do you talk to in telstra to do this?  I am sure this 
service is available because ISDN networks between businesses located on 
different sites work this way, IIRC...

thanks in advance...
