317669 2005-01-24 22:22:00 Hi people I had an electrician come to my house to install a new jackpoint for me, I had only 2 to start with, both worked fine. The electrician wired the new jackpoint into one of the old ones now whenever I connect to xtra from either of the jackpoints that he touched I get a max speed of 45.2Kbps yet when I use the other jackpoint that wasnt touched i get 50Kbps which is normal. Does this mean that the wiring they did was faulty/not done correctly what should I do :(
Also im getting jetstream 2morrow will this problem affect the speed of that to?

317670 2005-01-25 00:00:00 Connection speed is only part of the equation. You need to test and compare the download speed to get a true indication of whether things have changed or not.

Have a look at this thread (pressf1.pcworld.co.nz) for more information.

It's impossible to say for certain if it would cause a problem for Jetstream, it would depend how close to the exchange you are, but I doubt it would effect it.

But FoxyMX has wise words, the "connect speed" is not always of high relevance.

317672 2005-01-25 01:14:00 Oh ok I did hear him mention CAT 5 cable is this the right cable he should have used Overdrive_5000 (4950)
317673 2005-01-25 01:25:00 CAT 5 is network cable, telephone lines are just twisted copper. ad_267 (6193)
317674 2005-01-25 01:28:00 That should be fine, as long as he used one of the twisted pairs, rather than just a "couple of wires" chose at random from the 8.

Take the plate off and have a look. A pair has one wire with solid colour (green, orange, blue ...) and the other has the colour and white. I suppose you should look at the other end of the wire, too, and make sure he used the same pair at both ends. :)

317675 2005-01-25 01:34:00 That might be a bit hard to do the jackpoint is not one with screws on it I think he called it a 'magic box' and the cable is under the house wired into the other jackpoint Overdrive_5000 (4950)
317676 2005-01-25 01:44:00 CAT 5 is network cable, telephone lines are just twisted copper.


Cat 5 is just twisted copper too. ;) They are both made to standards. They both have similar impedance, and, used for telephone / modems, there's probably not any measurable difference in performance.

It wouldn't work if he didn't Graham. If one end was orange/orange-trace and the other was orange/blue-trace the connection would be open circuit.

It is more likely that he didn't use a cable pair, and you should also check that he didn't leave loops of untwisted wire at the terminations.

BTW, IMHO Cat 5 is superior to telephone cable, even at lower frequencies because it presents a more stable impedance to the devices.

317678 2005-01-25 05:04:00 But Billy, I said "measurable" difference . I agree it's "better" cable . But in telephone service, its not going to perform any better . I don't think telephones are very critical about the impedance they work into, and you're not going to get much in the way of interfering reflections (the wavelength at 4kHz is 75 km; at 300 Hz it's a lot longer) . You run out of signal (from resistive losses) long before you could run into that sort of trouble .

Modems are made to work in telephone systems, but the last time I looked the isolating transformers were the good old traditional 600 ohms . The twisted pairs are about 100-120 ohms . 600 ohm lines are hard to make and expensive .

Can't I joke? Even with a smiley? :(
