in my job fixing internet connections (here in the UK) I constantly collide
with bad adsl signals and dodgy home telephone wiring and I need a device
that tests the presence/level/quality of the adsl signal on the line -
something I can plug into the BT socket and get an accurate reading. I
specifically want to test for any deterioration in the adsl signal in
extension sockets coming off the main socket.
I figured there must be a gadget somewhere that can do this but I've never
seen one. I've heard the argument about using routers but I'm not
interested in that, I'd rather get a dedicated device. Does anyone know of
such equipment?
thanks for any advice. |

These (DSL) line test systems have existed and do exist. They are
available to industry, but are rather expensive, so you need to reveal
your budget before I'll bother researching and posting a list. We're
talking tens of thousands, IIRC for a reasonable tester.

Consider a simple signal strength meter, with a 20 KHz high pass
filter.
Study DSL some more. Understand the bands used, the frequencies used.
Then you can come up with something realistic to test with, assuming
your budget doesn't allow for a dedicated tester.
But... Why are you running DSL to multiple sockets? Catch the DSL line
as it enters the premises and run the modem there, then split the POTS
line to the sockets as needed. Don't try to run the DSL places where
it is 'not needed'.

What does a router have to do with this problem. That's an ethernet
device, and knows zip, zero, nothing, nada about DSL.

I see your logic, but most domestic grade routers sold in the UK
are hybrid devices and include a DSL modem and often a wireless
access point too. I suspect you are not in the UK, are things
different where you are?
Oh and we pronounce it "rooter" and not "rawter".
I certainly carry such a device for diagnostic purposes.

They are available but expect to have to pay lots for one. Google ADSL
handheld for a range of them.

Get a router that's compatible with DMT [http://dmt.mhilfe.de/] and you'll
be able to get a frequency response graph from each point where you'd like
to test.

thanks for your feedback, that search did bring up some gadgets. The first
one was over £3000...oh dear. I did see a Vonaq 100 pretty cheap but I'm
not sure if this device will serve my needs. I liked the look of the argus
testers but again I'll make sure I'm sitting down when I check out the
price. |

I can't do that. If the customer wants the adsl 'there', I've got to make
it work there.

some routers give detailed info about the adsl signal they're connected to
but I'm not going to do it that way. I'm talking about the home/plastic box
routers here, not the pure ethernet devices. |

[/quote:b7d548d117]
Of course you do, but that is not at odds with Peter's advice.
Ideally use a filtered faceplate on the master socket and
connect all the extension sockets to the filtered side.
Only the socket for the router (wherever the customer wants it)
should be direct from the line (use an RJ11 plate to prevent a phone
being plugged in).
Using multiple filters, one on each POTS device is not ideal,
despite what some ISPs might have you believe.
Tackling installations, especially marginal ones, using this
central filter approach is more important than investing in expensive
test equipment.

[/quote:dc5ef844fe]
US, and they go either way here. I use stand alone DSL modems, and
then feed a router which is a seperate box. Oh, and at least around
here, we say rooter too.

[/quote:dc5ef844fe]
I know of some that do give diagnostic information, but I'd be
reluctant to depend on it.
But again, why wire DSL to all the phone jacks, instead do the jack
nearest the entry point, put the DSL modem (or router/modem) there,
and put the rest of the house's sockets on the other side of a DSL
filter. |

thanks for all the responses here. I think that once funds allow, I'll be
getting a Vonaq 500 tester. It's closer to my (recession-hit) budget and
from what I gather it will provide the info I want from the line. If anyone
has used one of these devices and wants to enlighten us all about it's
pro's and con's go right ahead.. |
