BT infinity cable between BT socket and modem - is it RJ11 or RJ45

[ Edited ]

Hi all,

 

Hope you can help. I'm due to have BT infinity installed on the 9th Sept. I currenly have a master socket at the foot of the stairs, where a high quality RJ11 cable runs between the socket and my current DSL modem which lives under the stairs (where standard RJ45 LAN cable takes the service to the rest of the house).

 

I've been unable to find out for sure from what I've read so far, if the cable between the wall socket and the modem for BT infinity is the smaller RJ11 (where hopefully my existing cable can be re-used) or the larger LAN style RJ45 (and therefore I need to change it) and was wondering if someone could advise?

 

This is because whilst not a long run, changing the cable is a little fiddly and would like to do this before the engineer arrives.

 

Many thanks for your help.

The BT chap will fit a NTE5 socket, as I understand it, this is not RJ11 compatible, then attach a cable that is slightly thinker and  looks like the usual telephone extension.

This will run to the modem (he brings it with him) then a RJ45 will connect to the Infinity Homehub.

 

This is how mine has just been fitted if it helps.

Hi

The Openreach engineer will replace your main front plate with one of these

The socket on the left will accept either RJ11 or RJ45, the right hand socket is standard telephone jack.

Thank you for your replies so far. Just to clarify it is BT infinity fibre optic broadband I'm having installed where I belive they replace the adsl v1.0 faceplate (which I currently have) for a different one for BT infinity.

Infinity is only fibre to the dslam out in the street .... (from an exchange msan)

 

Your "old" copper pair connect your vdsl modem, to the fibre in the cabinet.

 

All supplied info accurate.  :smileywink:

BT have a special data extension kit to connect from the master socket in situations like the OP's see http://bt.custhelp.com/app/answers/detail/a_id/13751/c/346. It seems these have better screening than standard to avoid interference.

 

Not exactly sure if you have to order one in advance or whether the engineer carries them and uses them where required.

from http://www.productsandservices.bt.com/consumerProducts/displayTopic.do?topicId=29023 Installing BT

 

Infinity in your home

The engineer may install a small data extension kit and some extension cabling within your home if needed to make sure your equipment gives you the fastest possible speed.

 

so he/she will bring it

Re: BT infinity cable between BT socket and modem - is it RJ11 or RJ45

In answer to my own question (now the infinity has been installed and excellent it is too...) The new vdsl faceplace takes RJ11 *and* RJ45 :-) In my case the engineer re-used the existing high quality RJ11 cable from my previous modem so no re-running of cables was required and made the whole job take less than half an hour for the engineer. :-)

 

The faceplace socket is an RJ45 which RJ11's fit by design. If the engineer had used a network extender socket this would have been wired to the faceplate with an RJ45 ethernet cable.
