wiring this up advice......

hi these photo show my adsl nation xte-2005

I may want to do an extension from the back of it as shown in the photo.

Can I use one length of cat5e from this to the point I then want phone and ADSL outlet or would I have to do two cable runs?

But I may not want to extend the VOICE/Phone part. Just the adsl and if so. What colours on a Cat5e cable would I attach to the back of the adsl nation socket? (adsl part)

thanks

On a Cat5 cable there are four twisted pairs of cable. For an ADSL extension you should use one of those twisted pairs and connect to the A / B ports on the back (labelled ADSL).

For a voice extension, connect a separate twisted pair to pins 2/5 of the voice section.

To make any connection, you should be using an IDC punchdown tool.

You should be fine to use the same CAT5 cable for both voice and ADSL. That said, you might find it better to connect a router at the master socket then run a cat5 ethernet connection from it (in order to keep a strong sync speed).

I just really want or rather would prefer to move router. Why BT put master sockets in such stupid places in new houses I don't know. Think it must be just easy for them as on wall closest to pole.

I need to route the cat5e wire anyhow so will try it one way, if it doesn't work I can always stick router back there & stick a rj45 on it then get. 'Switch' for other end.

I would personally go for the leaving the router in place and running a length of cat5e to the room you want access, terminate it in nice dataport !

Ports 2 and 5 for voice extension.

A/B for DSL.

Run 2 cables.

Cheers Sin. I may try it this way. Just wasn't sure if there was any need to run x2 cables. You know from the other thread what I am trying to achieve.

Now I have the tools (punchdown krone/crimpers etc) rj11/rj45 plugs. I can have a go. If it doesnt lower my broadband speed then router can move. If it does then it will stay where it is.

I thought the A/B terminals were just unfiltered terminals? So you could just run one cable connected to these going to another socket. Once you've got that other socket you can then decide whether you want to just use it for ADSL only (so just use a BT to RJ11 cable to connect the socket to your modem/router) or you can use it for ADSL and voice, in which case you just use a filter/another filtered faceplate.

Edit: Yes this would appear to be the case. No need to run two cables or use two pairs of cables, simply make use of the unfiltered A/B terminals then re-filter off the new extension if you need voice as well.

It shouldn't matter if you run the adsl and voice wires in the same cat 5e cable. Just make sure you terminate the same each end and use pairs and it should be fine.

Which totally destroys the point of putting a filtered faceplate on the master socket. Why on earth would you want to put voice back onto your now nice and clean DSL line?

235 are for Voice extensions and NOTHING else.

AB are for DSL extensions and NOTHING else.

I would run 2 cables personally. Do not like the idea of running DSL and Voice signals down the same cable, despite being in different pairs. Cable is cheap, running 2 gives you more flexibility and really is no additional cost/effort.

That's a fair comment but it really wont make much difference. Cat 5e is unshielded so all you get is an extra two plastic sheath which provides no additional interference or noise reduction. The twists in cable are what reduces interference.

I'd use 2 pair BT Spec CW1308 for internal telephone cabling, and indeed I already have. It has less pairs, it has a solid conductor for good and solid termination in the IDC connectors and the 6p6c connector. The number of twists are ideal for the frequencies too.

Cat 5e will do but it's thicker ad has more twists which are not needed.

Sin_Chase · 14 Aug 2011 at 23:46

I used proper 2 pair BT spec cable also.

A DSL extension is just an unfiltered socket in the first place

When you use a filter to plug in your ADSL modem/router, your ADSL kit connects straight up bypassing any filtering going on. The filter part is for the phone socket itself, that is, the voice part. If this wasn't the case then you wouldn't be able to just plug an ADSL modem or router straight into a phone line using BT to RJ11 cable (ie. no filter at all), but you can.

In other words the whole point of a filter is to split off the VOICE part only. DSL signal is and always has been raw unfiltered so you can't put voice back into it as it was always there in the first place. The ADSL kit will use the frequencies it needs, the filter stops the ADSL frequencies 'spilling out' onto the voice part of the line. The XTE2005 documentation even states that the DSL terminals are unfiltered.

However with that said I personally agree with the point of keeping it DSL extensions only when running off the DSL terminals.
