Phone and 10base T FREE cabling and networking Helpdesk

 Phone and 10base T
I am planning to install a structured cat5 installation of around 20 devices. The existing phone system is to be upgraded later.
The phone company's equipment is nowhere near the data wiring closet, so, I was proposing to run two cat5 cables to each wall plate, fit an RJ45 outlet and a blank (using only the data for now, then later fit an RJ11 socket for the phones)
Basically is it OK to run phone and data cables in the same conduits? and to have data and phone sockets in same wall plates?
Finally, in one or two locations, laptops will be used on the network, but for short durations.
Would it be ok to use one data cable to serve two RJ45 sockets and use both simultaniously?
I live in UK so the terminology may be a little differant as so the technology but not much!
thanks in anticipation

Hi, Jeremy!

Here are the answers:

1) It is absolutely OK to run phone and data cables in the same conduits.

2) I would not recommend to install two RJ-45 sockets and then split one cable between them. By the way, this is a non-standard compliant solution in the USA. Instead, use an external adapter called "splitter". It plugs into the RJ-45 socket and has two RJ-45 sockets as output.

3) I would not recommend terminating your cables with RJ-11 sockets. Instead, use a normal Cat5 RJ-45 socket and then again use an external "Rj-45 to RJ-11" adapter. Using RJ-45 sockets will give you "universal" sockets that can serve both data and phone.

If you have any other question, please feel free to use Helpdesk again.
