Not a standard phone line per say. They are talking about ADSL
which should work on most pairs that don't go more then a couple
miles from
the local CO. It also assumes that a high error rate for most
applications
is acceptable.
Of course, I'd love to have my bell put this equipment in the
local CO and offer connections to some sort of ISP, but there are still
hurdles involving what type of connection do you have past the CO
and how much should they charge. Great technology, but the bells
aren't
quite ready for it.

Not unheard of. There are aDSL users getting 20Mb/s if they're close to
the CO.
Verison offers 7Mbs, I think if you can get the 3Mbs then they can do the
7Mbs over the same distance as well.
Brighthouse offered me 40 Mbps, on a cable modem.

Yes, and they are lying to their customer base too.Cable is now 120 Mbps here, but expensive.

They are building out more fiber right now. I got that offer last
year. It was about $65 more than my current bill, so it went into the
trash.

MAYBE they can get 2 or 3 Mb/s SUSTAINED RATE. All the other claims

total bullshit.
Tell the dumbass to DL a fresh distro ISO off kernel.org or other

fast pipe. HIS hooks will be the bottleneck, and NO, he will not EVER
get 20Mb/s.
I HATE goddamned liars!

IOW, to nearly no one. It also slows when saturated, as it would be in
a residential area, so even within the 4k limit, the actual attained rate
is significantly less on any given day, and dog slow on many if not most.
Lots of folks streaming A/V and DLing iso images and the same files
getting streamed.
Nice incorrect assumption there.When it is slower then there is a
rate limit on the other end.

You have no way of knowing if it isn't your pipe if you do not try to
fill it (multiple high rate streams). For all you know, it could be
(likely) slowing due to simple provider saturation.
Your test is to DL say an Ubuntu or Fedora iso image.Bart! <B@rt_The_Sheriff_Is_A_Nig***!.org> wrote:

If you see a constant download rate, it most definitely is a rate
limiter on the other end. If it is a bottle neck at the provider
you'll see the download rate going up and down erraticly. And slower
downloads at night. But over here that is not an issue anymore. Most
providers are so big that they are actually part of the internet by
peering with other internet traffic exchanges.

You try a direct DL and note the data rate, then you grab the torrent
and see what data rate it feeds. THAT is the test. Hard and fast speeds

Thanks, that's interesting. Can you tell me more about that resistor thatThe metal gate parts are very nice, except for the dead zone in the
phase detector.
The HC parts are far more nonlinear--more like 3:1 in slope, if not
worse, and with VDD = 5V, they crap out at 1 to 1.3 V--they just stop
oscillating. We had a thread about this back in July--see
http://groups.google.com/group/sci.electronics.design/msg/528c22e578dc8c2a

Thanks, that's interesting. Can you tell me more about that resistor that
helps the dead zone problem (which I also don't understand yet)? Is it
loading the output to ground?
AFAIK all 18-volt CMOS logic parts are metal gate. That's one of theAs far as I know, using CMOS will be better not least because better
performance seems to come from larger voltage ranges in all cases.
Also, as I
mentioned in answer to Jim Thompson, if the HEF4046B VCO isn't a
metal gate
type, but according to the datasheet appears to be more linear than the
MC14046, then I have some confusion that the datasheet won't bail me
out of
because it doesn't say anything about metal gates.
CheersThe main problem seems to be that datasheets (and Spice) tend to
emphasise
defined behaviour. If I'm after something most PLL makers don't consider
important, I'm S.O.L... but as there ARE soem more linear than
others, and
linearity of VCO is important to me, I'd like to know anything I can
about
fixing any deficiencies in those 4046's that do have high linearity,
and also
what undocumented details of manufacture might make them so much more
linear
than others, often touted as 'improved' in any way.
PS. Added S.E.D to the group list because this isn't so much about Spice
now..
