What speeds does everybody get with their 56K modems when downloading
COMPRESSED files via ftp. I want to compare it to my 28K modem to see
if its worth it to upgrade. I get about 2.8/2.9Kb/sec, in theory, this
should jump to 5.6?

I used to see something like 5200-5300 cps on good days (I usually got
48000/48000 connections using x2 and V.90, sometimes 48000/46666).

Keep in mind that "56k" modems actually negotiate speeds which are no
more than 53k and possibly lower, at least in the US, due to limits on
the signal they can produce and still fall within legal guidelines.

I've heard this before -- if correct, I need to adjust my thoughts on
the subject. I know I still get about 48kbps with V.90 (same as my old
x2 connections), so there must be other limiting factors.

That applied to USR's "X2" technology. It never applied to
K56flex (although it had other problems) and does not apply to
V.90. Getting 56K connections is still pretty unlikely for most
people though for lots of other reasons.

I have a Zoom V90. My usual ftp speed is between 4.2 to 5.2Kbs. On one
occasion compression kicked in and I sustained 10.2Kbs for a 1.2MB
download from France!

The manual for my Sportster 56k V90/X2 external modem says, in a
footnote: "Due to FCC regulations, receiving speeds are limited to 53
Kbps." No mention that this is limited to X2.
Has anyone *ever* achieved 56k on any protocol?
BTW, I'm in Canada -- and presumably beyond the reach of the FCC -- and
I've never done better than 31.2, thanks to a crummy phone line.

one thing you have to understand is that it going from digital to analog and
depending how far you are from a telco will determin how fast you will
connect. As far as the 10.2 kbs that might have beena uncompressed file to
begin with, when i was using an x2 connection anywhere from 42k to 51k most
files would avrg 4.5 to 5.5 now if i would dl a text file i would see as
high as 10k or so.
as far a the 56kflex and v90 they are just differnt proticals so there is
really no diffence in speed between them, v90 is just so x2 and 56kflex
modes are saported instead of isp's beening one or the other.

hope that clears up a few things

the best way to test the speeds is connecting the two modems directly:

modem <--------> modem
not
modem <----telco----> modem

that will give you the maximum speed without the problems of noisy lines,
analog lines, etc...
you can connect the modems with the modem-to-wall cable to both modems LINE
or WALL input

hope you try that, and sorry for bad english

I don't think this works as you have do dial-tone for the modems to detect. KAS
