I think I understand what you mean - does what I've put below make any sense:

He has a building, say (for the minute) there is three rooms and, in each room there will be three CAT5(e) outlets.

Now, there is only one cable running into each room, and he wants three cat5(e) outlets hanging off one cable.

Is that right?

There is a possible way to do this, and that's to wire them in series using what we call in the UK a 'BT Tool'. Basically, what you do is run the cable to the first female socket and use the 'BT tool' to push the individual wires onto the recepticle, then you cut another length of cable, and match the wires up and push the second set on to the first socket, and the other end goes to the next socket... and so on - you could call it wiring in series I suppose.

This would look like the ascii art(?) below

Each '-' is one twisted pair, in reality you'd need to do the same for each individual wire but I'm not gonna use eight dashes

[code]
[ SOCKET 1 ] [ SOCKET 2 ]
-------------| | | | ------------------| | | |
---------------| | | --------------------| | |
-----------------| | ----------------------| |
-------------------| ------------------------|

And so on, depending on how many outlets you need.

Now, if more than one PC is on this arrangement - it won't work so it sounds like it'll suit you down to the ground. A graphical rep would look something like this:

[code]
|========WALL================
|
----CAT5-----|-----[S]-------[S]-------[S]
|
|========WALL================
|
----CAT5-----|-----[S]-------[S]-------[S]
|
|========WALL================

</pre><hr></blockquote>

etcetera - you get the picture (I hope!) - if you hadn't guessed, [S] is a socket, '-' is the cable and '=' is the adjoining walls.

All you do then is simply hub-off the other ends of the cat5 (the ones above with CAT5 at the start) and plug a file server into the hub.

IMHO I'd prefer a switch cos it would run full speed for every cable instead of negating down to a fraction of the speed but that's just me though You can pick up unmanaged 8 port switches for a couple hundred quid (UK£)

If this isn't right, then I'm not sure what you meant! lol - sorry

Good Luck!
