This is done daily? Why the hell would we need to callibrate all the network daily Return path insertions are done but certainly not at 70dBmV and by people who have an idea what they are doing and that they'll get fired if they shove something that powerful down there.

you are certainly showing ignorance by saying the strong signal would break it....duh. but then again it wouldn't take much signal injected at a customers isolator box to take out the directional coupler, that would be no use as it would most likely have affect on the silly customer or neighbouring ports on the tap. If any of the network techs have taken a tap apart they will tell you they are grouped.

You are showing extreme ignorance with the figures you put, +70dBmV is like saying that plugging a 110V device into 220V current will break it, you know as well as I do that in normal function the levels hitting the fibre nodes are nowhere near +70, christ by the time they get to the uBRs which is pretty much all fibre to the headend they are only +0 or +4. The amount of return path nodal drop out faults suggest you are talking crap sir even mentioning this, it's like saying a snow storm kills Sky reception, yes we know but it's so rare it's not worth talking about.

There is a lot of things that the vast majority of ntl employees on this board don't know about their HFC network, there are many who think they do but the people with hands on experience at optical/RF level are very few and far between here. I raised issues with a former boss about the silly information on frequency allocations that were being made available on .com for the return path. ntl employees were openly giving out the safe combination numbers to would be sabotage/disgruntled employees and customers.

Most don't need to know about it. Tech and IP network support don't need to know, is that such a problem?

Frequency allocations? You what? A quick google will show the forward and return path ranges, a look on Robin Walker's site will show the downstream frequencies and some of the common upstream ones.

Go away and talk to someone who understands to component level, and they will tell you it only takes about 5 capacitors, 4 resistors, 3 coils and 1 transistor, and a PP3 battery to give 1 watt of RF, enough to wipe out an entire node!

How often does this happen? So why talk about it? What exactly is your problem if you weren't sacked etc, etc, that you feel the need to undermine the people that are there, and when is it going to enter your head that there are two sides to every story, not just the one you hear, and the franchaise you worked in isn't the only one in the company?

If I was such a bitter twisted ex-employee with all the components at hand to make hundreds of these, wouldn't I of been knocking them out by now?

Dunno? Next on your hitlist maybe? You clearly are pretty bitter and twisted otherwise why go on about it? Why are you posting on this forum, most of the time you're about as helpful as a waxwork in a furnace and about the only thing you do is complain about how evil ntl are, some of it I agree with but you just go on, and on, and on about it. Doesn't it ever get boring? Don't you have better things to do? I'm here to help people, you sir are trolling this forum and nothing else. You rarely bring anything of value to this forum and your main source of assistance to people is telling them how crap ntl are, the local management, how many people have been made redundant, how much the RF engineers hate their job. They have a lousy deal, I know this. I do actually try and help make their lives easier. Your posts just make them look like they are constantly whinging as you seem to feel the need to.

Gonna leave this thread has become another forum for 'Escapee' to vent his frustration and belittle ntl, not that he's a twisted or bitter ex employee
