The problem you're running into is a bug in the Max OS (talked to Ascend
about this one). Someone else here had a similar problem recently and I
replied with the steps to fix it. I attatched it below...
As for the V.90, on our Max 4004 and 4048, we're using 6.1.0 and have had
no problems at all with it. So far, I think the highest speed that I've
seen connect to us is 50666 or 50667 (something like that). Our 4002 is is
only V.34 and gets hit only if the other two Maxes are full--that still has
6.0.4 on it.
Anyway, here's the fix for your Max:
Check the following:
Ethernet --> Mod Config --> WAN options
Make sure that you have as many IPs in your pool(s) as you have
Go into your Max and change the following setting:
Ethernet --> Mod Config --> Auth
Auth Pool =
Change it to "No"
You will have to reset the Max after this or you'll never free up the IPs.
After setting and saving the above option:
Hit ^d then d (diagnostics)
nvr (this resets the max)
