Hardwiring an ADSL modem

Anyone done this?

I've just moved my office (hence I've been quiet for a bit) and the new place is right on top of the main BT telephone exchange.

BT had to run a brand new cable from the top of the building down to the main frame inside the exchange, so we have one long unbroken cable from the building into the frame.

At the top end, I can therefore hardwire the ADSL modem to the ADSL modem and have the same unbroken cable run straight from modem to exchange.

As I understand ADSL, the signal is actually analogue, so could benefit from the lack of connectors and cable joins?

Anyone done this and, if so, is it worth it or am I wasting my time and should I just stick the BT ADSL V1.0 box on the wall and use a plug?

I wouldn't try and rock the boat too much as far as BT are concerned; they rely on the fact that everything is "the same", whether you are 10 feet or 10km from the exchange.

If your service fails and an engineer is called to your premises to investigate, they will expect everything to be as normal, regardless of the fact that you are lucky enough to have a single bit of wire direct into the exchange!

It won't make any difference.
If you're close enough to the exchange for ADSL to work, then it won't work any better / faster / more reliably hardwired.

mole is right as long as you have new cable and connectors. If you solder the connections, you risk a cold solder joint and thus shoot-self in foot.

CAT V (and other telecoms cabling) is never soldered.

The BT box on the wall has push in style fittings (standard BT issue) which is what I would hook the modem cable into.

I know the BT engineers reasonably well here - would be no issues there.

It's a case of whether or not an ultra clean line is a benefit. I can't actually see how it couldn't be - ADSL must presumably use some kind of error correction?

I worked at Motorola for 11 years. When someone said 'hard wire' it meant a solder connection vs a removable connector. Perhaps I didn't get your point of what you meant by 'hard wired'

Sorry, my fault - bit misleading with my terminology!

What I mean is rather than putting a socket on the wall, and connecting the socket to the BT frame in our office, I just cut one plug off the modem lead and hook that straight to the frame.

The closer you are the faster it can go. They could give you a 7MB SDSL connection if they wanted to. I had an office in Seattle once and we were down the street from the phone company they said we could get 7MB SDSL if we wanted to.

Precisely. And I'm assuming the reason is line quality.

Which is why I'm thinking of doing what I'm doing - keep error correction to a minimum by offering the cleanest possible audio signal path.

I used to work for BT Openworld ADSL department and satellite on tech support and billing support.

If an engineer was to ever come around for any reason and see that you had tampered with any of the equipment they had provided to you then you could either have your account disabled or if you were ever to call for support they could refuse you as you have modified it yourself.

Lock it away and have another ADSL modem that you can hook up real quick if somebody were ever to come by. I really don't think that hard wiring would give you a noticeable performance boost. It would only help if they gave you all the speed it could give. They are probably throttling it anyhow. It would only help if that was the weakest link and I doubt if it is.

My understanding of the way that UK ADSL works is that it is capped at the exchange and tinkering with your modem wont give you any increase in speed.

That's really not an issue for me.

This is the question - performance. I realise that the speed is capped at 512/1mb/2mb etc at the exchange end - I guess the info I'm after relates to getting as close to that theoretical maximum as possible.

I guess I'll just do it anyway - it certainly can't degrade performance.

As you seem to know the BT guys well why not ask them to fix you up with one of their 500Mbps connections :)
