merits of twisted pair telephone cable?


[link to this post]
 
Since work has been done by Openreach I've been seeing better synch speeds but have been seeing quite a few resynchs over the past couple of days (lot of Openreach vans in the vicinity)

IIt did cross my mind however that it could be noise/interference, I've read from various sources that twisted pair phone cable is better than your standard flat RJ-11-RJ-11 stuff supplied with routers.

I note that ADSL nation are selling some but wondered if there is any truth to this before I place an order?

Thanks both.

I knew about twisted pair in Ethernet terms but was not sure whether it would make any difference in telephone cable terms.

Its only a short length so not worth bothering.

It can make a difference - on my old ADSL2+ moving to a twisted pair from flat untwisted gave an increase of around 300-400kbps. It was demonstrable by changing over and seeing immediate differences up or down.

In some locations it may make almost no difference, however it should not make the situation worse.

I may take a punt.

Openreach guy that came thoroughly tested the line and said apparently it was completely 'pure' (I wasn't here at the time so am getting it second hand but I assme he meant without interference) so am keen to ensure I minimise any internal interference as the cable runs near my surge protector.

I may have missed the point here smile but if you compare results when connected directly plugged into your BT Test Socket with your 'normal' connection point then that should tell you what you are after.

My Master Socket is in the loft (?!) so I use a faceplate splitter and a good quality RJ11 down to my study. I've then monitored/compared things from the test socket and from the RJ11 'extension' to make sure I'm happy I'm not picking up any noise/interference.

If the modem is in an electrically noisy environment, the 1m lead from either test socket or the front plate, when refitted, to modem may pick up noise. It is the flying lead not fixed wiring the OP is talking about.

We bought some shielded belkin version a few years ago for a few metre run to the router. Definitely helped the noise margin out back then. It's also a bit more robust running under the flooring

Yep I have one of the 'soap on a rope' type ADSL Nation filters and am referring to the lead between that and the ADSL WAN port on the router.
