What's on the splitter?

Ok, was watching my brother in law have his (brighthouse) cable modem
hooked up today and was talking to the installer as he dropped a new line
and installed a new gray box to the house. I noticed he ran the drop
down, ran it into what appeared to be a trap in the grey box (trap had a
blue label on it and little else) and then it hooked into a grounding
block and out to another cable with a splitter on it. Now the part I
can't figure out is, on one side of the splitter it had a brass looking
cylinder that looked like a trap, and on the other side was the output to
go in to the house.
I asked the installer about it and he said it was a cable drop, saying
since this is a straight drop off the main wire, it would be at 27 db,
much too high for the house, I asked if it worked as a terminator and he
said yes.
So I asked him, if he orders cable tv will they be able to just switch
him from the main office, he says "no, they'll have to come out and
remove this trap and remove this terminator from the other side of the
splitter and run the tv service off of that.

I found it odd that a totally seperate line is really neccesary, and I
gathered from what he said, that the cable tv uses a stronger signal than
a modem which I found a little backwards.

So it was installed in this order.
Main line.
Trap
short cable.
splitter.w/ output to cable modem
/ output to a another cylinder looking thing that screwed directly into
the splitter.

What purpose does the terminator/signal drop on the splitter really
serve?

What brand/model # of traps does bright house in tampa use?

How does the company audit people? I've had my brighthouse service for 8
yrs and I've never seen someone come to my house and physically inspect
my box, my gate stays locked and I have a 6' privacy fence. (btw- I
already pay for everything so one look at my $110 bill should let them
know I'm not stealing anything and probably why they've never come out)

If someone was to remove the trap and put in a dummy trap and use a
splitter in the cable modem line in the house, would they be able to tell
the trap is not there without physically opening the box and inspecting
it? What if I was to replace it with a trap that looked like that one,
but only blocked a couple of channels?

Is there anyway of making an existing trap a dummy trap where it passes
all signals?

I'm just curious and was hoping that someone in the tampa bay area that
had specific knowledge on this could help me out, but I'll take whatever
help I can get.
TIA!

I'm having cable internet and tv hooked up this Saturday and plan on
finding out some of these very same questions. From what i know,
internet uses the same 6mhz frequency as a TV station for download and
a 2mhz for upload (you'd think they'd stop assuming people are going
to download more than upload and just go with 6mhz for both). The
Internet Signal can be decoded by newer TV's with a micro-processor
and MAC card else the modem will do that. As far as traps go.. there
are MANY different methods to trap a line. I know newer service are
using RF chips to set and remove traps remotely or even allow a user
to login to their account and add remove services this way. It's
smarter, easier and safer for them. I think Charter (who will hooking
up my Cable Sat) uses this method. I'm not positive, but there is no
trap in my gray box at this point, so i'm curious as to where else it
would be. I've heard of people buying a wireless transmitter that they
attach to the underground line (so that it's hidden and undetectable)
which then can be picked up from an inside receiver which will process
the signal accordingly to "steal" the signals.

I'll let you know what i dig up from the Tech this Sat. Any specific
questions you'd like me to ask?

Good luck. The way you're thinking, you're gonna need it.

Dear Cy,

It's a trap to block certain frequencies, such as phone or internet
services. It's not a terminator, in the fact a terminator is there to
control signal leakage on unconnected lines. It sounds too big to be an
attenuator which is what they use to decrease too high a signal level.
Attenuators are itty bitty things that look like an extra long connector.
The thing the two lines were joined at is called a ground block. Very
necessary to keep from frying your equipment next thunderstorm and can also
affect pix quality if poorly grounded. The extra cable is used to keep
moisture out of the connection as well as providing slack to keep connectors
from pulling loose or anything from snapping off when they shut and tag the
interface. If you know someone inside the system they can tell you by trap
color and the color of the tag the interface is locked with what the trap is
for. Don't expect an honest answer from a technician, a confidentiality
agreement not to give subscribers technical information is as signed as soon
as a clean urine screening is obtained from a prospective employee. Too much
knowledge can be a dangerous thing and cost you rewiring of your house at
the least. I can't count the number of service calls, at $25 a truck roll
(shows how old I am) to turn around a splitter someone wired backwards or
remove a house amp they had cranked up, just killing pix quality.
