278289 2004-10-04 22:14:00 Have a colleague that runs a home based business, and is on Business Jetstream (500 MB cap)

He is keen on moving to Jetstream surf 256k, as the cost is lower, and he would get a more managable 1 GB cap. As a home based business he is elegible for it.

However Telecom help desk say that the performance would be unacceptable. He is a distance from the exchange, and can presently only get about 450 k download speed on the full speed business package.

The help desk suggested to him that by the time they speed limited his connection to 256 kbs he would be back to "about dial-up speed" performance.

This doesnt sound right to me.

Any suggestions where he can get the right answers, if the above advice so far is a bunch of porkies?

Anyone with similar experience of a marginal JS speed and the effect?

278290 2004-10-04 22:27:00 Speed is fine.... Much much better than Dial-Up any day!

I think they're just over-exaggerating the point. I'd recommend Surf, or one of the plans that are due out at the end of the month!

278291 2004-10-04 22:38:00 It is possible that this could happen - the further you are away from the telephone exchange, the greater the signal degradation.

Although for phone systems the effects are not noticeable, when passing assymetric digital signals through copper wire, you will certainly get degredation.

Telecom are hoping to resolve such issues by implementing 'booster' units several km's from the site, so that the user can get a faster speed.

The greater the original bitrate at the exchange (for FULL jetstream this is around 4-8Mbps), the more relative speed you are going to get at your end.

Obviously taking this into account, it the original bitrate is something like 256kb, then if you are a long way from the exchange, you are more likely to see the effects.

278292 2004-10-04 22:48:00 Where abouts does your colleague live godfather? Have you considered alternative broardband options? Pete O'Neil (250)
278293 2004-10-04 22:57:00 He is in Wellington.

Point being he has Jetstream now. It works.

he has already done the splitting of the line, owns the router etc. So alternatives are not an option really.

The question is simply:

Will 256k be degraded, when maximum speed is 450k due to distance from the exchange.

Telecom say yes it will be degraded, he will not get anything like 256k when speed limiting is applied on the Surf plan.
But he gets 450k now, with no speed limiting applied.

They cut it back to 256 so why should it go lower. Mine is basically a full speed connection and they cut it back to 128k. This can be proved when they slip up from time to time and you get full speed for a while.

He should still get 256k. Telecom probably just want him to stay on the more expensive connection.

After the media release for the 2Mb speed I asked them a question about how to switch over straight away as my billing date ends the 21st and the new plans take affect 24th so did not want to wait another month. They replied back saying it was only valid for Xtra customers. I told them to go back and read their own media release which clearly stated others from different ISPs also qualify.

One hand there does not what the other is talking about.

278295 2004-10-04 23:26:00 Only one way to find out. ;)

My original line test showed that I was just outside of the 5km limit and that they recommended a full install to ensure good connection. I took the risk of a self-instal due to financial reasons. At the time it was jetstart and I was told that would be the best I got. I was more than happy with jetstart speed and connection.

When surf came out I was unsure if I would get full surf speed due to distance but the cheaper price meant it was worth the risk as worse case scenario is that I would only get 128k speed. It worked without problem and have never noticed speed degradation even on large downloads.

278296 2004-10-04 23:39:00 Hi TechDUDE , is the loss you describe a constant , or does it vary depending on the bitrate? ie if this chap is having 4- 8 M sent and only recieves about 10% of the speed at his end, does that mean from 256kb he could only expect 25kb or so ? Or does the signal degeneration vary wrt bit rate? KatiMike (242)
278297 2004-10-05 00:03:00 Home based businesses are allowed to use the home plans,why is he even looking at the more expensive and lower data cap business plans?

I even have 2 accounts for my business,an unlimited home account and a 1g plan for the shop,the bill for both is under the one account........

He is not "looking at" the business plan .
He has had the business connection for a long time, before there were any 256k plans available for home use, at the cheaper rate .
He already has a full install . It works fine albeit at 450k .

KatiMike has grasped the exact issue above .
If he only gets 10% of the speed currently, will he only get 10% of the 256k?

Telecom help desk suggest so .
I don't see why that would be the case .

Also suggesting he "try it and see" is not much good, as he will be stuck with the unuseable speed for a billing period minimum .

Hence asking for experience of others .

Thanks for the comments so far .
