Hi Xnet.

I have just been through the exercise of trying to resolve poor VOIP call quality and slow ping times. It appears that this has now been resolved by an upgrade of the backhaul. Thankyou to Maverick & Cameron from Xnet for the support on this forum.

This however is the third or forth time in two years that Telecom Wholsale have had to increase the backhaul to resolve what turned out to be congestion.

For the benefit of all, can someone from Xnet comment on the following general questions on ADSL backhaul  quality?

1.What quality obligations do Telecom Wholesale have for ADSL backhaul? I believe they only have to allow an average of 30kbps or 45kbps per customer?  are there obligations for latency, jitter, packet loss on the backhaul?

2.I believe that Telecom Wholsale have reporting obligations to the Commerce Commission and ISPs? Does this report identify congested DSLAMs? If this is correct, why are congestion issues not identified and resolved proactively before users have too many problems? 

3.Depending on which traceroute application I use, I get significantly different packet loss results. Which wxnz domain should I be testing to, which app do you recommend? (Previously it has been winmtr), and why do the packet loss results vary so much between winmtr and the other apps (pingtest.net, pingplotter, visualroute)?

4.At what point with Speed, latency, jitter, packetloss or MOS should a user be raising a fault ticket for investigation?

I hope you can enlighten us.

Regards Allen.
