Hi gb
I agree!
I also was not quite clear in my statements either.
We only daisy chain each rooms telephone circuits from a central
locatiion using loops in the pullboxes, having blank cover plates over
those pullboxes until it is decided which one will suffice for the
room furniture layout.
For computer we usually use the 75 ohm cable direct to the central
area for internet, and for internal networking the 6 wire cable is
used. It too runs from each room to the central area. If the
internal network only goes to rooms B and D only those two connections
are made in the central area.
In my house I have a shielded twisted pair going to each room, in each
room it is daisy chained to all possible outlets, at least 1 on each
wall, in some cases two on a couple of the walls. Unless it was used
at one time, there are no connections within the pull boxes.
However one decides to handle their wiring and extra's it's better to
have and not need than to not have at all.
Price is also a consideration! Running 6 telephone lines from a
central area to each room in the home can get quite expensive and
overly redundant for most home installations.
In addition, some cities charge 10 to 13 bucks extra on the permits
for each pullbox installed, even when those pullboxes are used for
non-permit required applications.

I would like to know which municipality or government entity these building
codes (permit charges) are coming from. Category 5e cable is very
inexpensive and the number of telecommunication outlets does not change --
whether daisy-chained or home-run.
Daisy chaining STP cable just introduces potential ground loops, since no
single ground potential point is established (grounding section of NEC and
EIA/TIA),
Luckily as long as the contractor does not staple the wire continuous along
the studs (just at the "rough-in" plate) .. these nuisances are relatively
easy to correct.
Who taught you this physical cabling method? It is also contrary to BICSI
certifications.
The National Electrical Code has been changed to reflect the EIA/TIA
standards for structured cabling and often takes precedence over local
codes, UNLESS the local code is more stringent or specific for
fire,health,safety reasons. For example, although ROMEX is permitted under
code, DuPage county (IL) as well as city of Chicago strictly forbid its
usage for electrical wiring. This stems from tragic fires and safety (e.g.
1959 elementary school fire in Chicago with large loss of life)
