NTE master line box has only one socket.

This is where the test socket is that you should take the router stats from, after removing the faceplate you will see the test socket within.

So, it seems as though you do not have any DSL filters in the system.

The router (inc filter) has been plugged directly into the "test" socket i.e the BT netwiork, having removed the NTE-5 face plate. The download speed registers as approx 4.5Mbps the same as with the face plate in situ and router connected to face plate and the same as when plugged into the secondry socket in the office

As mentioned. the router, telephone and bell are connected to the socket outlets via approved filters.

What are the attenuation and noise margin figures and exact sync figures?

Even with twisted pair cable it is feasible to still get noise causing problems, and lots of extensions like you have is not good.

Is all wiring uses the twisted pairs, and NOT split across two pairs? i.e. blue and white, and white and blue are used, rather than a mixture of blue and white and orange and white.

Andrew,

Thanks for reply . As regards the attenuation, noise margin and sync figures I can't tell you. If you let me know how to get I'll try.

Only two secondary boxes are in use. The one in the office for router connection and the one in the garage for the external bell. the one in the lounge is unused but there for possible later move to Sky services.

I hope this answers your query on the cable; Standard internal BT cable is used. Connection are to pins 2 (blue/white), 3 (orange/white) and 5 (white/blue). This configuration is used throughout.

For stats http://kitz.co.uk/adsl/frogstats.php has details for many common ADSL routers.

The wire on pin 3 is possibly causing an imbalance, and picking up noise particularly on the longer extensions, lift it off of the connector like in the photo above

Andrew,

Thanks for link to obtain stats. I know my friend is off on holiday to Bermuda (lucky fella) very soon for 3 weeks so I'll try and get rhese asap. Would you know what figures would be the norm?

Andrew,

re ring wire. I'd recommended that a i-plate be purchased and connected. This has arrived but not yet installed. I've told my friend that the external bell will no longer work and that he should consider purchasing a electronic telephone ringer which he can plug into any socket. - hopefully it will be load enough to hear outside.
