The Netvanta router from Adtran are accessable remotely using either a telnet session and through a web browser. They can be accessed quite easily on a local area network but for access from the internet, they need to have enabled acces from the wide area network optioned enabled.
In an earlier post I had a customer who had a point-to-point T1 connection between two offices. One of the offices in in NYC and the other is in the Bronx (unfortunately I had to go to the Bronx twice for this customer). They were doing VoIP between their two ofices with a couple of NEC Aspire phone systems. The problem was getting the quality of voice up to a nice level even though we had QoS enabled and configured correctly on both routers.
We checked their local area network for problems and the circuit itself - driving verizon people crazy (don't feel bad for them). I even tried different flavors of quality of service configurations and also enabled diffserv and packet tagging on the phone systems. Also monitored bandwidth usage. Nothing helped. No metter what we did, the voice was horrible whenever they started a download. Adtran couldn't helped with this problem. I like and admire Adtran's tech support as they are ver very good and often helped me get out of trouble. But this time they overlooked this solution.
Here is the solution. If you know of anyone, or it's you yourself reading this, with a couple of Netvanta 3200 routers trying to do quality of service and it just is not working our right then check that wieghted fair queuing (WFQ) is enabled on the router and not FIFO.
Once I enabled this option the quality was great.

What a difference one queuing technology can make over another and of course one checkbox in the configuration.
The Netvanta routers from Adtran are really good devices.
