Have a USR 56k Voice Win RS, Model #2974, using Windows ME on Dell Dimension XPS 500Mhz, P3. MSN is ISP. Have been connecting at 45K. Present access number is being replaced with 7 new numbers, none of which we can connect at anything better than 26.4 or not at all. Do have another computer which connects at 44 or 45K every time. Appears our phone line is OK and in the soon to be replaced number, our modem is OK. Have contacted MSN Tech Support and followed all their suggestions, but nothing has changed. Not real experienced at this, but any suggestions would be appreciated. Is this my problem or MSN's?

Suggest you use Hyperterminal connected directly to modem's COM port as described at
www.modemsite.com/56k/x2-hyperterm.htm

then, give modem
AT&F1
and dial your current 'good' number; wait a minute or so, and click the hang-up icon; then get the diagnostics (and post them here):
ati6i11y11

The, dial the new numbers and do the same thing and post those results here too.

Aloha! Richard.

Might try disabling X2 by using S32=34 in the Extra Settings.

Thanks Bob,

Made the change you suggested. Still connect at 26.4.

I have just been through a long process of trying to get a 5610B to connect consistently using the V90 protocal. What I see right away in your post is that the low speed connection has a SNR (signal to noise ratio)that will prevent you from getting a fast connection. It needs to be in the 40's like your good connection shows. I thought it was noise on the line at first. Did everything possible to clean it up. Finally got an IRF filter from Radio Shack for $11 and now it connects at 50.6 all the time. Your problem suggests something different since you connect to at least one number OK, but you might want to consider this. Some people have reported dimmer switches, overhead fans and all kinds of stuff interfering. Worked for me.

After trying Bob's suggestion to delete x2 which didn't change the connection rate on new numbers, tried S32=66, which disables V.90. Increased our good connection from 45K to 49K, but had no effect on the new numbers.

Don't believe anything about the CONNECT speed when you use x2 (V.90 disabled).
x2 is infamous for reporting connect speeds that have no relationship with the actual connection.
Check your throughput.
www.modemsite.com/56k/x2-thru.asp
And post-call diagnostics which show initial and final up and down rates.

Richard,
Throughput for this number is really meaningless, since that number will be eliminated March 6th. Really interested in your comments on hyperlink data submitted above.

The 3750 values in both the aty11's at
43 and 41 are getting close to the '56k=no' value of 50.

Where you got 56k:
Roundtrip Delay (msec) 8
Status uu,5,12N,12.3,--0,1Y,0,43.0,16.5

The --0,1Y indicates the modem hasn't detected any line padding (probably incorrect, but not impossible), that there is 1 RBS link and you are on a really old type of coedec (1Y).
If you get throughput anywhere near the mid-40kbps you connect at, and it holds - you should thank your lucky stars. (I'd like to see the ati6i11y11 after at least 30 minutes online with browsing and some downloading...)

New line:
Roundtrip Delay (msec) 12
The new number probably goes to a more distant CO, possibly involving more RBS links, and you probably should disable 56k and see if you can get higher than 26.4k. Thank your lucky stars you had such a good connection with a very marginal line, and if you really can sustain the mid 40's on the old line, perhaps check out the numbers of other ISPs available to you....

Oh, and if some of those terms I've used are Greek to you - there's some explanation of RBS & Line Coding and how it affects 56k modems at
www.modemsite.com/56k/why56kis.asp

Aloha! Richard.

Richard, Not trying to be a pest but, have taken computer off the phone line and replaced it with a laptop which has a 3COM 3CXM356 modem. The same phone line and same dial ups, that we previously submitted data on, give us 44k at either number. That says to me my phone line is good. Is that bad, or am I not understanding the term line??

I still think your line is 'marginal' and I'd really like to see the
ati6i11y11
after a 15-30minute on-line session.
IE - use your regular connectoid; surf/download; disconnect; then go to Hyperterminal and issue
ati6i11y11
and post the results from your high-speed connect.

Aloha! Richard.

> Last Call 00:00:46

The link diagnostics show that the last call was only 46 seconds, make sure you're using Hyperterminal setup direct to the com port the modem is on and NOT using the modem name.

See http://modemsite.com/56k/x2-hyperterm.asp for setting up Hyperterminal.

Then make at least a 30 minute connection to the internet of normal browsing and downloading, then disconnect. Once disconnected, don't let the modem reconnect or dial out again, start the Hyperterminal session and first issue ate1 (may be entered blindly so be sure to enter it correctly) then issue the ati6i11y11

Obviously, I am not doing something right, as I tried again today with the same results. What I did was:

1. Connected to my "good number", surfed for over an hour, disconnected.
2. Setup hyperterminal session using COM port 2 (not my modem name), and after approximately a minute hit the disconnect icon. Then issued the ati6i11y11 command. It still shows the last call as about a minute.

What am I doing wrong?

Are you dialing out in Hyperterminal? Not suppose to, just query the modem with ati6i11y11.

Did you setup Hyperterminal and save the session as shown at http://modemsite.com/56k/x2-hyperterm.asp ?

Try it this way:

1. Click Start, Run, enter Hypertrm.exe and click OK

2. Type in for Name: Terminal ,then click OK

3. Next in the "Connect using:" box, select 'Direct to Com X' (X being the Com Port your modem is on, Com2 in your case), and click OK

4. In Port Settings set 'Bits per second' to 115200 and click OK

Now enter a couple of commands to verify that you can "talk" to the modem.

5. Type ATE1 <hit enter> (E one, entered blindly, allows you to see what you type afterwards)
(modem will respond "OK")

6. Type AT [init string] <hit enter>
(modem will respond "OK")

Now in the Hyperterminal menu click 'Call', 'Disconnect'

Close Hyperterminal and you'll be prompted to save the session, click YES.

Then make at least a 30 minute connection to the internet of normal browsing and downloading and then disconnect.

Start the 'Terminal' session.

Type ate1 <hit enter> (E one, entered blindly, allows you to see what you type afterwards)
(modem will respond "OK")

Type ati6i11y11 <hit enter>

Highlight the data, click Edit, Copy

Click Call, Disconnect

Close the 'Terminal' session.

Connect to the internet, come back here and paste the data in a post.
