Absolutely correct regarding manual tuning. One of my clients is at the end of the line regarding attenuation (114) and signal over noise of 2, both extremely poor readings. Good is in the range of 40 and 15 respectively. Talk to you ISP and they should be able to give you those line condition readings without issue. I haven't found one that doesn't. The ADSL service package my client has is 2.5Mb D/L and 1 U/L, however, due to the poor line conditions the slightest issue anywhere in the network circuit causes voice dropoff among other things. They have G729 on the voip system which has reduced the traffic by a huge amount 80kb down to 8kb per conversation. Tuning the queue for all of these conditions of course is best guess and go from there, the next step for us is to drop the service package down to 1.5Mb and 640kb allowing a much lower stress level on the line making it much less prone to breakdown as there is no way to change the attenuation and signall over noise ratios. Get to know your ISP and I sure you'll find they can be helpful. ( be nice to them even if they are clearly inexperienced ). Do the math on the amount of bandwidth you actually need for your phone(s) Do the math on how much bandwidth your remaining services require ( or can at least get by on) Make an educated guess on the initial settings and go from there. Try to make sure you get those line readings as you can waste a LOT of time tracking down queue gremlins that don't exist ;-) Hope this helps Bob
