Today's handy tip for keeping my brain working: do eat lunch, don't let it be stodge (bread and vegetables; lard a bad idea), do caffeinate severely afterwards, add sugar as needed for half-hour bursts of brainpower. I got a spare web server with a dodgy serial console server running Solaris 9 with Solaris Volume Manager (formerly DiskShite) and iPlanet 6.0SP7 successfully serving 404s! (Which beats refusing connections.) Unfortunately, I have to install 6.1 instead. That can happen tomorrow.

Our DSL appears to be running on the same quality of damp string as our voice line. It's acting like there's bursts of noise every now and then that wipe out the connection for ten to a hundred seconds. That you can pick up the phone and hear background hiss and crackle almost as loud as the other person's voice doesn't augur well. I'll try swapping out all possible plug-in devices before moaning at BT. Has anyone else tried reporting a DSL that's acting like a bad dialup connection?

Also, could people please offer unqualified non-lawyer advice on the legalities of putting a sign out front that says "THIS DOOR IS UNDER 24-HOUR SURVEILLANCE. IF YOU LEAVE A CARD WITHOUT KNOCKING, I'LL HAVE THE EVIDENCE." Just a thought.

non-legal advice on the legalities... that, sir, is a contradiction =P

You need to get yourself a copy of the Royal Mail book - its a guide of what the minimum service requirements the post office/royal mail must give.

Is the door going to be under 24-hour surveillance?

The problem with 'IF YOU LEAVE A CARD WITHOUT KNOCKING, I'LL HAVE THE EVIDENCE.' is, it could be construed as a threat... which is bad.

If it were me, I'd collect the evidence then go and LART the postmaster/mistress

Some lines (for various reasons) can just be noisy and at Bulldog we used to advice customers to put them on all extensions. Have you got them on all the extensions with stuff plugged in? BT wouldn't have installed broadband if it was too noisy. We could lend you a couple to see if it helps before you go buy some.

you only need a microfilter on the telephone line to which your DSL modem is connected. The fact that the dsl is dropping out sounds like an exchange problem, or the line joining your local RCU - remote concentrator unit (the green boxes you see at the side of the road). In any event, you can always dial 17070 and run your own line checks before calling an engineer.

Huh? Surely you only want the filters on the lines that the modem is not on? And an unconnected socket shouldn't need a filter. Only lines with stuff plugged in (that's not the DSL modem).

Yes, but the DSL line filters take out all the high frequency signal... that's the point - all those other devices hanging off the line generate random noise up in those frequency ranges, so you need the DSL filter to prevent them from leaking back into the line. Now, it's also possible that really badly wired sockets with nothing plugged into them could be generating signal noise too... but plugging a filter in front of them is hardly going to help. As someone else said, though, they do usually test line quality before okaying a DSL connection, and it's intermittent, so it's unlikely to just be bad wiring. Could be bad wiring plus a persistent damp/drip... that'd do it.

More seriously, definitely do the master-socket isolation test thang everyone else has recommended, if you can. You may not be able to, depending on how badly the place is wired, though...

the filter acts to connect the remaining pairs. DSL runs on the 2 unused pairs that phonelines have. Your phone connection doesn't change - still reds and greens.

*blink* AFAICT, you guys are using some different version of phone-fu than we are down here in .au then. We get "ADSL line filters", that are specifically for use only on the lines that the DSL modem is not plugged in to. This "microfilter" sounds like something different...

Ah, right. Here we go:

http://www.hometech.com/learn/dsl.html

DSL doesn't necessarily run on unused pairs... It only does that if your telco/ISP sets it up that way. If it does, it's a lot cleaner, because theoretically you're on an otherwise unused line. It can run on a in use pair too... that's when you need the line filters on everything that's not the DSL modem, in order to filter out the interference generated by those devices that will affect the DSL signal on the line.

I can't think of any good reason why there'd be a problem with leaving out a sign like that. OTOH, it does create the expectation that there is surveillance... I think there have been things like that with fake cameras installed in building hallways, in which crimes were then committed, and then when surveillance tapes requested... Ooops. I'm not sure whether that resulted in problems for the fake camera installers...

Back when I lived in Cardwell Terrace, Holloway, we got broken into only six weeks after moving in. The landlord put up a fake camera outside the door. In the following three months there were eight muggings, one shooting and one stabbing just outside our flat, and the local CID guys became regular visitors (so much so that we were on first-name basis). Of ourse, we had no tapes to give them, but the formalities had to be followed. I think the landlord got thoroughly LARTed by them - and in retaliation he kept part of our deposit when we left a few months later.

Oh yes. It's just the data storage that's the issue... if you're actually setting up surveillance, then go right ahead, including putting up the sign.

After Steve took a day off work last month while the British Gas man silently left a calling card downstairs (a literal one, thankfully!) and the call-centre wench refused to apologise for the loss of a day's holiday, I feel your pain and am also sorely tempted by the sign you mention.

Hmmmm. Americans are reputed to enjoy hanging signs out such as "THIS HOUSE IS GUARDED BY SHOTGUN THREE NIGHTS A WEEK - YOU GUESS WHICH THREE" and they seem to get away with it. Perhaps you just need to inject the right amount of humour into your sign, or threat.

More seriously, ideally it'd be possible to find the first fork in your internal wiring, put the DSL modem on one leg, and a filter on the other leg keeping your signal from doing strange stuff in any of its multitudinous legs. An unterminated extra pair ("bridge tap" in Telcoese) tee'ing off is bad for your signal, though reputedly the ones preventing me from having DSL are multiple kilometres long, and that's beside the point that 10 km of old copper are on the live path and I'm "only" 5 km from the CO.

Meanwhile, a webcam on a Yvahk box *should* be easy to organize, though I've never quite had the CFT. A senior co-worker has, and we have lovely JPEGs of people coming in and out of the front door and various machine rooms at work.

Have you tried tracing all the wiring and disconnecting all the phone sockets you are not actually using? I suspect bad wiring, either inside or outside your premises.

"This area is monitored by CCTV with recording. This system is operated by D Gerard for the purposes of prevention and detection of crime and monitoring the actions of callers. Please ring bell."

I could do with CCTV on my front door too, having a noticeable occurrance of parcels left by my back gate in the rain while I was in.

We had a package left on the front doorstep - in full view of the road and therefore all of the passing students of the two nearby schools - for a whole day. Despite the fact that the package contained expensive jewelery, despite the fact that jewelery was clearly listed on the content and despite the fact that it was sent registered post. The card they were supposed to have us sign before turning the package over to anyone, was conveniently still attached to the box, unsigned.

Attempts at complaining to Australia Post about the current contractor's habit of leaving packages where they can (and possibly have been) easily stolen have produced naught but a useless complaint number.

So, at least you get the card :)

For DSL connectivity, find your master socket, remove _everything_ after that, so there is nothing at all except the master socket. Now plug your DSL modem in as the only device. Does it still fuck up? If so then there's a BT issue; if not then it's an internal wiring issue and you have to fix it yourself. The same test would be good for your voice circuit; plug a microfilter and a cabled - not cordless - phone in; do you get the bursts of noise? If so, BT issue. If not, internal wiring issue.

Everything up to and including the master socket is owned by BT. After that it's yours.

The "leaving a card without ringing" is a world-wide phenomenon. I have a List of carriers and couriers that I will not use domestically for this reason. I work out of my home. I *am* home every minute of every business hour anytime I'm expecting a delivery or tradesman. Notably, United Parcel Service and the US Postal Service are not on the Do Not Use list. DHL heads the list in bold print and italics.

The suggestion of checking from the master jack at the point of entry is an excellent one, and should be your first/next step. The filters exist only to keep shoddy phones from causing problems with the high-freq DSL signals (which in spite of the name, are radio freqency analogue signals -- "modem" is spot on for the device). You will probably be able to get a good feel for the likely result of the master jack test by plugging a normal phone into the master jack. If you hear the same noise on the line, it's likely also just as noisy up in the DSL's frequency. Those test results in hand will allow you to face the telco with "Someplace, you must have a pair of wires not affected by damp or being chewed by squirrels. Find it."

I'm coming in a bit late, but thought you might like to know that when we first got ADSL the line was incredibly noisy -- eventually worked out that one of the microfilters that came with the modem was faulty, and when it was replaced with a new one (from clarity.it, as it happens) the problems went away.

If you have a modern master socket (NTE5) then checking what happens when all extension wiring is disconnected is best. Unfortunately we don't have one, which made life a bit difficult.
