BT help please
 

Hello,
Just joined. I should as an electrician know how to sort this problem out but have got out of depth.
my house has a new style BT incommer box (NT5??) and is a
ADSL enabled and working fine with my new BT Home Hub 2.0.
I have two Cat5 cables run from the BT box for extension phones. As soon as I hard connect either to the customer side punch down of the BT box I loose the broadband. Am i being stupid or is there another way I should connect. All connections are good.Cheers :erm:

Sounds like the telephones are dropping down the line power to much for the ADSL to work.

For example in the past phones and even ADSL modems had a REN number, something between .2 and 1, all the phones connected to the same network could never when added up have a REN greater than 1.

It's one of the reasons as to why multi handset dect cordless became really popular..

You could talk to BT but as they only tend to cover the outside witing upto the master socket (and or the BT homehub for which they'll ask you to unplug all extensions to test) they'll charge for an engineer to fix...

Makes sense, thanks. I will call bt first, if no joy ther must be some kind of amp?

When you say you have CAT5 to extensions - how is the connection being made at the NT5 ? :confused:

Re: BT help please
 

I presumed he was getting mixed up with CAT5 and standard telephone extensions...

Which does bring me back to my original point as most people don;t realise but long extensions will have an effect of lowering the maximum ren number that the system can cope with

I hope that you don't forget to use filters on every extension that you use?
