Ok...to answer some questions:
Cable Guy... i see alot of RED and BLUE labeled coax tips or jack's on most cables i see when i look into a neighboorhood box... if blue is digital that makes sense... but the red label doesnt make any since what do u mean by it is voluntary and involuntary disco? im pretty familar with the filter system around here... comcast will send a regular basic signal to a line but a technician must go to the house and place a filter which im geussing will block freqeuncies or channels 37 and up... and if you want digital comcast your going to need the digital box and a digital or regular basic signal on your line
These aren't coax tips. These are like the seals that the power company puts on the power meter to make sure that you don't steal power...they're made by the same company. We just clamp them on the coax line themself...either to identify or to secure the disco'ed tip.
You've got the premise of filtering correct...from the head end, you can get regular cable...but if you only want basic cable, they have to roll a truck to your house and have a tech trap or remove the channels from your line. If you want them back, they roll the truck again, and then the trap gets removed from your line, and you get your channels back.
There are two types of filters, by the way: Positive filters, and negative filters. Positive filters, although rarely used, add a frequency or a harmonic shift to the line so you can receive a specific channel. Negative filters remove a channel or a set of channels. Back in the "day," the positive filters were audited by your boss at Time Warner weekly. Now, they just look at the converters on your truck and make sure they're in "T" status either on ICOMS or CSG. (really old back in the day: my college town's MSO, Adelphia, used negative filters. Bring out ladder, remove traps, volia...free HBO, Showtime, and Cinemax. Kept that way for 4 years)
another thing if u know can u explain how a regular neighboorhood is network i know you have you local boxes what is done at the main cable office for digital cable.. how do they determine and give u more channels and service on digital cable... cause i tried ordering some PPV... and never got it i called up and the operator said some thing was wrong with my cities system and will be fixed by the end of the month....
Most cable systems today use HFC (Hybrid Fiber Coax) technology. Basically, the HFC plant uses fiber to carry video and telephony from the "headend" or CO to the optical node serving a particular neighborhood. At the optical node, downstream optical signaling is converted to an electrical signal and carried via coax to drops at individual customer locations.
Because the carrying capacity of fiber is much higher than that of coax, a single optical node will typically support a number of coaxial distribution feeds. A typical ratio is four multidrop coaxial cables from a single optical node.
This is how cable companies can save money in the long run. One HFC Headend can serve many different communitites...or deliver content per specific zip code or however they break their HFC plant down. Your PPV ordering goofup might have been caused by a problem in the upstream bandwidth. Upstream data works in the same way...goes from node to the converter, then back up the fiber to the headend.
ok about hacking the cable boxes what will i need ima search google on this too but u know any sites or tuts on this? this cable shit is kinda tricky... OH YA and in my local box out side my house is that silver metal box placed in the out side cable box a phiber to coax conveter? or what is it?
Hacking cable boxes isn't for the faint of heart. There really aren't a lot of sites or tutorials on how to do it...like I said...try to go to the Salvation Army or Flea Markets in your area, and pick up some of the digital boxes that they have. Then take it home, break the seals, and play. Good tools to have are a scope, logic probe, and multimeter.
how can i determine what line has a broadband signal on it? im tryin to ge some free broadband cuz im going to get a broadband modem and i already got like 20 comcast SN's from friends and fellow enemies
Unless they put a pancake filter on your line to specifically dissalow signals on your line, most of the lines have broadband signals on it. Specifically, the pancakes just prohibit the signal from being sent upstream. Now, I'm not sure how your cable system does things, but we use something called DOCSIS for cable modem authentication. Each cable modem has two MAC addresses...an ethernet address, and an RF Address. When it's plugged into the network it goes something like this:
Cable modem scans the channels, looking for data.
Cable modem thinks...Hey! I found data! Let's listen for a few seconds to make sure that it's stuff that I need to be paying attention to.
(In cookie monster like fashion, the cable modem snarfs up some packets, but, is careful not to leave crumbs everywhere)
The cable modem then decides: Yes, this is data I need to be paying attention to, or no, this isn't what I need, I'm going to keep looking. It'll keep looking until it finds something it is suppossed to be paying attention to.
Then the cable modem still listens for a little bit more, for the data to say, "Hey! This is how we're sending the data back. Wait your turn, then send your information to this channel."
The cable modem does just that....it waits its turn in line, then says, "Hey! Mr. Head End. I am MAC address 00-04-BD-94-DB-42, and I need to get a configuration file." It'll repeat that every 5 seconds or so until it receives a configuration file.
The configuration file that it receives contains the upstream and downstream limits for your cable modem, as well as what the internal RF ip address is, and tells the cable modem to finally allow information from the ethernet port to start talking on the network, and the cable modem will send it.
and about the cable pirating... how often to technicians go around neighboorhood checking lines? i heard about every half a year the audits do so? thats pretty neat though how they can send a carrier signal and catch hot lines... but will they do this to lines that connected with out those white tags with the houses address on it?
That honestly depends on the cable company, and the rate of theft in the area. I know that there are areas where I live where the cable company audits on a weekly basis. Otherwise, they will do tap audits about once a year or so. They will also scan for signal leakage usually about once a week, or so, if they're in the neighborhood.
Hope this helps;
