Problem to access the Internet with windows xp

[G.B.]

I'm with a problem in my windows xp.
When I try to connect to Internet (dial-up modem) I got the 680 error, like if my telephone line it was not connected to my PC, but then I made a test and look what happened ...
I took my phone off the base and then my modem got the signal and had connect normally ...
So I had seen that my modem is with a problem to take the signal from the telephone line ..
But the worst ...
I got online only a 29.2 Kbps (my modem is a 56Kbps).
What is happening ??
Please help me ...

For 2K & XP:

The most important thing to remember about dial up is that the maximum you can download ANYTHING under absolute perfect conditions is 6.7kb/s, so don't be frustrated with your speed, remember it is only 56K (actually 53333). To understand a little better, most dial up connections have a connect speed of somewhere in the mid 40K range, which is very good, so say you connect at 48000, to find your maximum throughput divide that by 8 which gives you 6kb/s, which actually very good for dial up. The tweaks I have provided will help you maximize that throughput as best possible, don't expect super speeds by tweaking your dial up, be happy if you are getting 6kb/s.
