My mum just moved into her new house, i just went around to check the place out and it looks like the place is wired with cat5 and she seems to have a combination of rj45, bt, rj45/bt ans rj45/rg45/bt wall plates.              
The thing I want to know is shouldnt all the cat5 go to a central location? Try as I might i cant find where it goes to.

Hi, yes it should, but you assume the person who installed it knew what they were doing, unfortunately the current state of the electrical trades industry does not train electricians (who are most likely to have installed said cabling) as to what they should do.

I suggest you start pulling faceplates off and try nut out what they have done.

Thanks for the reply.
I did pull of the faceplates when I was there. Looks like they used cat5 for the telephone, using just one pair from it.
Each of the rj45 sockets has cat5, apart from that thats all I could see. Could it be in the crawlspace under the house? I thought it would have been somewhere inside.

Wish they wouldn't spend money on those expensive BT outlets instead of spending time to get the topology right.

But yeah, without any mandatory standard there is lots of house wiring is being done by techs who are more interested in doing the cheapest possible job than in designing a network, so its too late when you find out its all been done to the old standard (and there's more than one premises standard to choose from). Not sure if there will ever be a solution, but some compulsory training would be a start.

I guess you haven't found a network cabinet anywhere yet, do you know where the line comes in from the street? Its normally at front of the building unless you can see an external termination point around somewhere else. The cabinet should be reasonably close to that. I'm guessing there must be one even if only for the RJ45 outlets since they can't be done without a central distributor located somewhere. It might be hidden in a cupboard or something.

Does one of the faceplates have 4 or more RJ45's on it, if so then all the other single RJ45 sockets may end up their as the hub.

This just frustrates the heck out of me ...... Cry

But hey it's not complosury and some tradesman always know best ...

This has been pushed to any many industry bodies as we can, builders, electrical, suppliers and yet we still see this ... oh well suggest you get the tradesman back to redo the job.

Yes I am a employee of WxC (My Profile) ... but I do have my own opinions as well Wink

I still see looped wiring being installed in new houses........

As Cyril said; pull off the wall plates, get a torch and see if the cables run up or down the wall.

Then have fun crawling either in the roof or under the floor to follow it all.
