Hi chris,
We have couple of stores around the town and all are on a t1 with ISDN for backup except for one on ISDN. Some t1 are shared for voice. We use t1 or ISDN to connect to the main store in order to communicate with the main server and get internet connection. Our internet is share with another company.
We are currently using a cisco router and some are on some old gandalf bridge (need to take it out) to share connecting within stores.
If a sub store's t1 goes down, it looses connection to private network, internet, and main server. The ISDN backup is there so that we can manually set to dial to SBC to get back into the private network.
I am thinking of getting rid of the ISDN since it costs us around 30 bucks for just 1 ISDN bri interface if the T1 proves reliable and if there is a cheaper mean. I am looking at the DSL but i wonder it will be able to connect to our private network like how our current ISDN is setup.

We have several, over 15, offices connecting using DSL/cable and use VPN (Cisco 3005 main office, Cisco 3002 remote offices) and have very little downtime. I even have MRTG monitor the lines every 5 minutes. Ever get an email every 5 minutes non stop during an outage? This really is quite stable. We are going to be installing the above setup as backup connections for the frame/relay connections. DSL may not be cheaper than a single bri but the speed gain is well worth it. Ken
