Level of the DSL pilot tone?

But you have an ethernet connection between your router and modem, so
I would think it has an IP address as well -> the assigned IP address
from your provider. But then, it only passes on packets, so it doesn't
do you any good It may have diagnostics, but perhaps not accessible
through a tcp/ip connection and a common protocol.

I don't think PPPoE uses IP...

isp home modem router
. . . . . . . . . . LAN
ADSL \ \ . . Ethernet . . ethernet
PPP ---------\ \------------ ------------- ---------
IP --------------/ /--------------------------------- |
================/ /===================================================
-------------\ \---------------------------------- |
---------\ \------------ ------------- ----------
. . . .
. . . . . . . . . .


IP isn't the only network service than can be provided over ethernet
or over PPP for that matter.

Often (but not always) a device that combines the modem and router
is used. Using a separate modem can reduce hardware cost in extreme
situations where cheap modem/routers get "gummed up" and need to be
reset.

We had a modem-router at work that would stop accepting inbound
connections at random times, we switched it to modem only mode
("passthrough") and used a linux box to do the ppp and router
function. Reliability has improved.

ipconfig /all /p

Surely you mean "ipconfig /all | more".

( "|" is the pipe command, shift-backslash).

That works with ipconfig, I just tested it. I had forgotten that you
can "pipe" into "more".

/p for "pause" seems to work for most commands, and is faster, but /p
doesn't work with ipconfig.

I used to use | "pipe" to feed the output of one executable into
another in batch files.

Ah, the obsolete knowledge I've acquired over the years... ;-)

Anyway, Joerg, you have a modem, and not a router? I think you're
right, a modem probably wouldn't have such an address - it's when you
are talking to a router (especially a wireless one) that you'll really
want to configure it with the IP address...

Hello Jim,

My cable feed is 18" down and comes up to ground level enclosed in
what looks to be 3/4" ABS, then has something like a shrink tubing
cover where it enters the splitter.

That's not how they do it out here. It's all on top of the dirt. We had
a wee brush fire down the road started by some stupid kid. It was out in
minutes but the house behind it promptly lost cable.

I had to re-lay my CAT5 to the swimming pool controller due to "teeth
marks". Used the 1/2" black stuff that is used for bubbler
distribution tubing. My electrician buddy says the underground
creatures don't like to gnaw on it.

We have a fox litter born here almost every year. The kits like to play
with anything. Pull air mattress plugs and what it hiss, toss over a
firewood stack and stuff like that. So we have to keep our yard "kid proof".

 

[Joerg]

Hello Jim,

I know. But with ipconfig this delivers:
"Error: Unrecognized command line argument "p"

[snip]

I only get a single page, but since you get lots of stuff, try...

ipconfig /all > filename.txt

Thanks! Oh man, DOS knowledge seem to be fading from my brain just like
a foreign language that I haven't used in a long time. This worked. But,
no IP address for the modem :-(

Yes, I can talk to the router but it's menu is a bit sparse. No speed or
line tests at all.

Hello Michael,

http://www.dslreports.com/speedtest?more=1

Is it safe? I remember that whenever I entered that site in the past I
got warnings and sometimes my router blocked it. Yesterday the ISP
called, saying my modem might be slowing things down and coached me
through their own speed test. Didn't work, guess the router blocked it.

Hello Tony,

I don't know that much about it first hand, only
what has been seen in newsgroups or websites.

AFAIK only the downstream stats are important, particularly
the Attenuation and Noise Margin. Note that Noise Margin
is not the same as SNR. NM is the margin above the minimum
SNR required for your ADSL modem to reliably sync with the
DSLAM in the telephone exchange.

See for example <http://www.kitz.co.uk/adsl/linestats.htm> .

Your line stats don't look bad, but that final negotiated
downstream rate looks very slow, compared to the upstream rate.

AFAIK AT&T caps at around 1.5Mbit/sec for their DSL.

Ah, thank you. Not everything has a technical reason.

Hello Tony,

Or to put it more bluntly, at the end of the day everything has a
financial reason ;-)

IIRC they used to have two tiers with the lower cost one being capped
around 400Kbit/sec or so. Maybe they still do but with cable among the
competitors that wouldn't make much sense anymore. In the really old
days there even was a third tier but I believe not with the former
Pacific Bell.

 

[David DiGiacomo]

Ah, thank you. Not everything has a technical reason.

But note that this tier of service only costs USD 13/month.

There is also 3M/512K service at USD 18/month and 6M/608K service at
USD 28/month.

Then you are very lucky. We pay $50 for 1.5Mbit/sec (AT&T). Lack of
competition, I guess. You can get those $19.99 deals but that's only for
new customers and the cable guys are really not much of a competition
for some users because they are pushing the whole TV/web bundle. Plus I
don't like the haphazard way they "lay" cable out here.

Nope, AT&T has the same prices everywhere, see http://att.com/1299

An existing customer can get into the new promotion by signing a new 12
month contract or upgrading a tier.

Another option would be to transfer to another ISP such as DSL Extreme
(same pricing at AT&T).

This is assuming you have your service listed as residential... DSL on a
business line is higher.

Thanks. Interesting. I asked a similar question when dealing with those
email issues and they said they didn't know and that the standard rate
is $49.95. I'll call them again to see (that 1299 website doesn't work
here).

Yes, but then you lose your first email address. Since I have my own web
site it's not used much anymore but occasionally I do get an email from
a really old client or their engineers.
