    Must be a little slow today -- at first thought HSI was some sort of
acronym for Home Shopping xxxx, as a slight on Radio Shack equipment, which
used to be better before they tried to widen their market and imploded.
    Yes, I get my internet from Comcast, but I wouldn't call it high speed,
unless compared to the DSL I used to have -- dumped that when I had to
reconnect my modem to get a faster data rate!

Oh, and do you have voice via your cable provider


    No. Cut that cord completely.

(the need to support emergency calling during a
power failure requires some different design points
for amplifiers, which can be addressed multiple
ways, but the easiest is not having to deal with
it at all :-)).


    Yeah, the demark test would be a hassle.
    As for a description of the connection, it starts with Comcast's
cheapest cable buried from distribution post at the back corner of my lot
along the fence line to the side of the house. As I recall, there are at
least two splices in that line because I cut it while mowing when they took
9 months to bury it (then sent a guy out with a shovel and a barrel
connector -- not even electrical tape) and the second is because they cut
it below the service entrance box rather than knock on the door to say the
police department reported RF interference in the area and try to fix it.
Can't recall what the issue really was, or even if it originated in my
service, but they just spliced another foot of cable on rather than pull a
new line drop. %-(
    In the SE box is a splitter to separate the Internet and video feeds.
The video enters at the top of the basement wall and runs about 10 feet to
where all my connections/distribution HW are. Most TV connections are
abandoned and unused ports on distribution amp (combo "low noise" amp and
1:4 splitter) were terminated with F-connector terminators (probably from
Radio Shack, too). Yesterday I replaced that with a passive 1:2 splitter I
had on-hand. Feed from there to Ceton runs about 15 feet and then up two
stories (basement ceiling to second floor baseboard), maybe another 12 feet
to a wallplate barrel connector; total run from splitter to wallplate ~27
feet. Another run of about 10 feet along two walls reaches the combination
surge arrestor/outlet strip. (It has surge arrestor options for RJ-11,
RJ-15, F-connectors, besides protecting the 120VAC.) A short drop cable
from there connects to the Ceton box. Cable jackets mostly just say CATV,
except the one to the Ceton, which is RG-59/U.
    I should add that the video problems appeared on the tv connected to
the Comcast settop box, too.  Haven't been on the passive splitter long
enough to be sure, but so far picture has been stable.
