Actually yes I would, I pride myself on the fact that every bit of work I do is completed to the best of my abilities and that the end result dosn't just work but that it works as well as I can make it. Perhaps these days having pride in the work you do and striving to excel are out dated concepts but not for this engineer.

Yes perhaps the the STB's and SACMs that ntl deploy arn't the best that money but would you be willing to pay more for a STB that costs £500 instead of £300 I think youd probably be in a minority. This thread isn't about the customer equipment though its about trying to maintain the integrity of the network that is used to deliver the data to those devices.
What many forget is that a cable network is a two way system, signals go down to the customer but also come back all through the same bit of cable. The way a system is designed is roughly funnel shaped every thing going out to the customer starts at a single point and spreads out, but everything includeing the interference has got to come back to that single point.
Admitedly if one person does somthing like this it possibly wouldnt impact either themselves or anyone else. But where does it end? if 4 or 5 connected to each street cabinet do it you end up with 40 or 50 at each fibre node multiply that again by the 700-800 plus fibre nodes feeding back in to the Headend and the result is a network that firstly breaches the DTI regulations for egress and secondly that won't be able to carry any decent traffic because of ingress. The network around London used to be the best example of it. Theres still to this day areas of that city that don't have DTV or broadband becuase it takes years to repair that sort of problems.
Anyone wanting anymore info on this sort of thing is invited to use this new fangled internet thingy which I believe has somthing called search engines to search for return path ingress problems, funneling effects within CATV systems etc.
Also worth a guick google is common path distortion just highlight the fact that theres enough problems inherent within a CATV system without adding to them.
