Running 5 or 6 telelphone extensions from 1 socket?

Hi guys,

How would it be possible to run 5 or 6 new phone extensions from one main socket? We're fine with cabling, crimping etc if needed.

Thanks!

I thought you could not exceed an REN of 3 per line. Add up the REN of each device connected to one line and if it's above 3 then you will have problems?

Afaik wiring it wouldn't be a problem, but you can only have 4 (i think) ren on the line so too many devices might cause problems.

Modern digital phones might be ok, its says in that article.

My post is kinda assuming you wanna use the extensions for phones

REN isn't an issue, I don't think, if the phones have their own power source (ie, a battery for a cordless). If they don't, just be sure the ringer isn't enabled on more than a couple phones.

I don't know how you guys wire stuff together in the UK, but here we just tie green and red together and branch it off.

edit: yeah, yours is definitely tricker than ours:

You can have as many sockets as you want really as long as you don't exceed a REN of 4 for all the equipment connected (it should state the REN on a sticker on the device). As a rule, a modern phone is between 0.5 and 1. If you go over 4, the line may stop working or the phones may stop ringing.

You can buy a REN booster though if you need more.
