mrbluesky: I was having issue uploading my stream to my stream hosts overseas. Massive latency issues between my router and the internet gateway, was causing my stream to buffer so badly that I was losing listeners. When testing to the same remote IP address from another provider there was no latency.

Two separate calls to the "Manila Telecom Call Centre" didn't do anything but raise my blood pressure. They kept insisting that they could find no problems and wouldn't escalate me to 2nd or 3rd level support.

I filed a formal complaint with Telecom management about the appalling customer service of their Manila help desk and after a 2 weeks investigation...I have not again had the issue for almost 2 months.

Will the wonders of the monopoly ever cease? Probably not.


Have you tried logging a case again with traceroutes and examples of when the traffic is slow, then if you don't get any joy tried contacting Telecom via twitter @telecomnz ??

99% of the issues are caused by poor home wiring.  When you tested the same remote IP with another provider was that at someone elses house, or did you use a different username/password to login in your router? Since I seem to remember that if you are with Telecom you can't use another providers username and password and see if they work.

I would highly recommend doing an isolation test and making sure your line is clean.

Yup. Contacted via @telecomnz (funny that the Telecom people say same thing) Are you sure you don't represent their company??? They spend a lot of their energy and time trying to prove that they are not the weak link in the chain, contrary to popular theory and testing results.

Tested all of that. Done had isolation test done...all is within acceptable tolerances. Testing on another connection was done properly and professionally (not our first rodeo by any means) and showed the latency was between my router and the external gateway.

Find it rather fishy that was having an issue almost weekly until I filed a formal complaint with Telecom. Now no more issues and not for some time now.

Back to the OP's question...

Line rates are a negotiation between the modem and the line card in the cabinet/exchange. The rate is usually a balancing act, to high for the conditions and it will be unstable to low and you're not getting your max potential.

Yes different modems, different chipsets and different firmware settings can result in different upload and download line rates, different conditions on the copper line to your house (eg: raining, humid etc) too.

Not surprised a newer firmware version for the Thomson is faster.

The difference between the line rate in the modem and the speedtest can be explained by two things..

1: Protocol overheads
Your speedtest data eg: http gets wrapped in pppoa at the modem wrapped in pppoe at the cabinet/exchange and so on.. this is all overheard which means less data in each packet payload relative to headers. This is just how it works.

2: Contention
Dedicated bandwidth is very expensive, if ISP's priced plans based on giving everyone dedicated bandwidth it simply would not be affordable.

Retail broadband is provided over a shared network. Bandwidth (the amount of data that can be transmitted) is shared between everybody who is connected to the network. This industry-wide method allows the ISP to provide a reliable, high-speed service at an affordable price.

Closest analogy is a motorway, with 1000 cars going south at 8am you don't build a 1000 lane motorway it's simply not economically viable. You have a 4 or 8 lane system and traffic queues and flows. Because not everyone is actively using the available capacity at all times it works well.

Sounds odd, can you post some tracert's to the server?

eg: Start > Run > cmd > tracert xyx.somedomain.xyz

Also (imo) the best way to contact Telecom is via their email us form, because you can attach screenshots and tracerts etc.  It appears this logs a job straight in their job system and whoever is available will process it often you can bypass having to deal with level 1 phone answerers this way and the job will be picked up by someone technical who can actually do something about it.

I have previously provided all of that information to Telecom at their request, via email.

I wish Telecom would introduce Annex M into their network, which can provide up to 3Mbit Uploads - which would be great for people who can't get the very much delayed release of VDSL services.

Ok, so I just wanted to understand what your *current* issue is?  Or is everything working fine right now and you're just complaining about past events?

There was an major issue on the 17th of April that a lot of people complained about, and post that a lot of things improved... Was that around the same time things improved for you too?

so let me get this straight.

you had an issue, filed a complaint, then the issue was fixed.

I'm a little disappointed though not surprised there hasn't been much by way of on topic suggestions for either the strange results from Telecom Firmware versus non-Telecom frimware or Telecom's online speed tests versus non-Telecom speed tests.

On the subject of firmware, I find it hard to believe that the 5th (which Telecom's is) and 6th releases would see upload speeds doubling.  Especially as even poorly rated products like the Linksys can achieve the same doubling, running near the theoretical max for upload.  If it is just the firmware, why hasn't Telecom released an update themselves since the performance as provided sucks big time (pardon the pun - "big time").

As for doing speed tests online, I've has another go with more or less the same results - Telecom sub 400kbps up, everyone else 780 plus kbps up, all within a few minutes, same house same everything, same modem connect up speed 955 kbps.  I did get one single unrepeatable 770kbps from Telecom's though???  My conclusion, Telecom's online speed test is broken, they need to fix it.

Are you aware of the technical problems introduced by Annex M? It's not just a simple matter of enabling it on the ISAM.

Start mixing Annex A and Annex M on different MPF's in the same cable bundle and managing crosstalk becomes a major issue and has the potential to impact all customers. Most people in NZ don't seem willing to pay to get master filters installed in their house now to maximise their speeds due to poor internal wiring.

VDSL2 is coming..

As has been pointed out in other threads in this forum, the VDSL2 product has been released to ISPs for some months now, however most to date still dont see a demand for the premium it would demand to peddle it, guess pest your ISP not us here and you might get somewhere.

I wasn't trying to pester anyone, I was merely stating that VDSL is a very much delayed service.

Regardless if any ISP's have the ability to offer the service - other than World Exchange, no one else to my knowledge is offering it.

I'm aware of ISP's offering Annex M in Australia, so I presume that the crosstalk issues aren't an issue there.

~800Kbps upload on a landline ADSL connection, just doesn't cut it in the Multimedia World that we live in today (think Full HD Video uploads to You Tube / Vimeo etc).
