Tot/Adsl Discrapency To Big To Be Plausible

[THAIPHUKET]

Several speed tests done in short order, TOT always around 4-5 MBps, ADSL against BKK constistantly under 2MBps.

TOTtests against BKK or against what?

No international bottle neck involved, how come?

Any plausible answer or pure window dressing?.

ADSL service in thailand is a shared system unlike in your home country where your dsl line only has you using it providing you with the full bandwidth you purchase. User contention ratios can be all over the place depending on how many subscribers in your area are on the same line\junction box, I have lived in places with great internet here and others that suck, same service and company. Until thailand gets rid of tot and cat and does a massive system upgrade to the telecommunications system here dont expect much for your baht. 3g will be a total waste of money as it still has to go thru the antiquated system in place.

Big difference between the TOT and ADSLThailand speedtester ping times....ADSLThailand ping time almost double that of TOT....ADSLThailand must be taking the long way to Bangkok/going through more server hops.

this is nonsense.

In Thailand as in every other country, ADSL has full bandwidth (and more) until the internet provider's network, where the bandwidth is then shared among all users. That is the way it is in all countries. But some providers certainly have less bandwidth to share between more users.

Sorrry but you dont know jack sh&t about adsl systems or contention ratios used here in thailand my friend,

Sorrry but you dont know jack sh&t about adsl systems or contention ratios used here in thailand my friend,

actually neither do you, all mini dslam and dslam are linked together with mostly newly installed optical fiber, few hundreds adsl customers aren't gonna kill the available bandwith , that's why we all have max speed within thailand but not on the international side.

[THAIPHUKET]

Please try to stay on the subject, it´s not about international connections, the real reasons for the bottleneck are hard to find.

We all have contract with TOT, whoever. What objective yardstick can the consumer use to check if the contractual quantity -within a reasonable range -- is actually delivered? TOT measuring itself is not objective. TOT may test it´s speed to the next knot , how do I know? ADSL tests against Thailand, where BKK? My above test show a 50% difference between the two, an unacceptable range.

How do you know, within Thailand only, if the contract is fullfilled?

I know one thing two of my best thai friends are system engineers for true corp who are involved in implementing the new 3g upgrade and have explained the problems very clearly to me. The main problem is the antiquated system currently in use most everywhere outside of certain locations in bangkok where the subscriber base is large enough to justify upgrades such as more fiber connections, anywhere else you are sharing not just the dslam but also the lines connecting to it, you can tell this easily by the time of day and watch your bandwidth drop to nothing as students come home from school and get on facebook or start downloading youtube vids, after midnite or so i can see my bandwidth rise back up to reasonable levels. I used to pay more for a premium service for a contention ratio of 1/10 whereas the standard service could be up to 20 or more subscribers on each line and by the way what the he*l is a mini dslam ??? no such thing ! Again back home you always had full bandwidth due to modern switching gear no matter what time of day unless you were on a cable system which is also a shared line system, cable companies finally fixed these problems by adding more nodes to better route the connections to compete with the telecoms.

adsl is never shared, you are alone on the telphone cable up to the mini dslam/dslam you just share the optical fiber while for cable old technology you share the cable up to the ISP(very old technology a huge bottleneck) or cable new technology you are alone on the cable until the optical fiber in the street.

Not it is certainly not that way in the UK. Providers that dont have local infrastructure (local loop unbundling) do have contention from the exchange to their ISP governed by their wholesale backhual (BT Openworld (or whatever it is called now) or Telesonia etc..) (and even those that do have presences in exchanges enforce this with their own customers - Easynet - well basically now BSkyB), however given exchanges with such facilities will serve thousands per exchange upto several kilometres this contention isnt often observed,

Never? Again, just a guess, the 3BB new mini-dslams (Huwaei powered) can easily support all sorts of firmware that can enforce contention at the local mini dslam, I guess they dont because it would be observable given number of subscribers, but still you're taking a stab in the dark there?

you're talking about something totally different, you're talking about bandwith(sharing ratio), i'm talking about the hardware.

[thunder30101]

How many times are you going to change your explanation ??? Again you dont know JS about the telecoms infrastructure in thailand. But then you're probably much smarter than a true corp. engineer who actually builds, maintains and manages the current system in use here, not europe. One good thing for true customers on 3g was they just had a regional meeting with huawei involving the subcontractors installing the 3g system to make sure they are all using the same installation specifications of the new equipment, apparently many were not integrating the systems to the same standards causing many speed and connection problems for customers which should now solve many current problems with bandwidth.
