Adtran Netvanta 3200

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.

Data wall jacks not working?

I went to a customer's office today on a call about a wireless problem. Once I got there of course other issues they were having came were remembered. One such problem was regarding two wall network wall jack that were "not working". I figured this would be an easy problem to fix, I started it before the more mysterious and dangerous wireless access point problem.
I checked both of the wall jacks with my laptop and they weren't working like they said. Not even a link light - forget about not getting an IP address. I toned them out to see if they even ran to their data room and they both did. But, of course, there was not patch cord going from the patch panel were the wires terminated to the data switch. I plugged two cables in and tested again. Both ports now linked u pthe the LAN fine. The customer paid for this. I guess to me and other in the support world this was a no brainer. I really think that if the customer had applied some simple troubleshooting skills and basic knowledge they could have avoided the bill. Oh and by the way, they wanted to start arguing that my company did the cabling and therefore they should not get billed. Go figure.
Now about the wireless problem. This has a few more twists in the plot than the wall jack problem did.
