I was asking last week about getting cable installed for telephone. I
have booked Virgin to do an installation but I gather that the broadband
comes via the tv coax not the paired telephone cable.
I assume therefore that a router connects directly with what ever tv
terminal that they install, not the telephone box.

They will provide a cable modem (typically by Cisco at the moment it
seems) with a single ethernet port on it. You can also elect to have them
provide a 4 port wired/wireless router (DLink), or provide your own. The
modem will come with some additional co-ax fly-leads and a F type two
port RF splitter to insert between the cable entry point and the TV box.
Hence allowing a split to the cable modem.

In mine, the cable enters the house, runs round for a bit and ends up at a
two-port F-type wall outlet in the living room, one of which port is
blanked off with a screw-on blanking plug (it appears to be intended for
FM radio, but doesn't seem to work as I once tried connecting it to the
hifi without success). The second port of the wall outlet connects to a
second, in-line, 2-port F-type splitter which divides the cable between
the cable modem and TV box.

Out of interest - because I'd like to do it to mine - is there any reason
why I shouldn't move the in-line splitter so it's before the wall outlet?
ie, is the wall outlet just a simple splitter too? That would be much
better as I could then site the cable modem with my PC kit, rather than
having it contribute to the spaghetti pile behind the TV in the living
room.

Its not a splitter, its a filter.
Don't do anything to it or they may bill you.
If you do move it, or alter the wires before it you may alter the levels of
everyone on that bit of the cable and may require someone to come out and
adjust it, if they find its you they can charge you.

I have often thought about doing something with the redundant one I have to
see what intermittent faults I could put into the cable network now I am on
Sky and can actually get some broadband speeds all times of the day. Skys
18M speed really is 18M all day.
