this for later reference because you can't be connected for some steps!)
you would dial "508-437-5599,,".
This will make your modem blind to the v.90 connection tones. You can
experiment with anywhere from 1 to 4 commas.
Some of our
customers have reported problems with either getting connected or frequent
and random disconnections. These problems are almost always due to
incompatibilities in how different brands of modems communicate with each
other, or signal quality issues arising from older phone lines. In an
effort to help those customers experiencing problems, we've put together
the following troubleshooting guide. This does not mean that your modem is
bad. It is only a reference to facilitate a better connection.
1) What type of modem do you have?
How do I find out? Under
Windows 95/98, click on the Start button, Settings, and then on the
Control Panel. Then double-click on the Modems icon. Your modem type
should be listed there. Unfortunately, some modem manufacturers will not
give a very detailed description; something like "56k
Voice/Speakerphone" is often not very helpful. Ideally, knowing what
brand and model you are having trouble with helps us fix your problem.
Why is this so important?
Somewhere around 90% of the calls we receive about
disconnections are from users of a few specific types of modems. While we
have selected our modems with an emphasis on compatibility, no single type
of modem can communicate correctly with all other modem types. In addition
to this, modems have a software component, called "firmware"
that is revised frequently, and often even new computers /modems come with
slightly outdated versions of this software. Also, you should be aware
that some computer manufacturers (e.g. Hewlett Packard and Compaq) include
troublesome (HCF) modems even with their most expensive computers.
2) So how do
I fix it?
What's the easiest way?
The quickest and easiest way to eliminate random
disconnections is to connect using the older (but more stable) v.34
protocol. This protocol has a maximum connection speed of 33.6k, slower than
the newer protocols (v.90, K56Flex). However, if you are having trouble, a
stable 33.6 connection is most often actually faster than an unreliable
What's the best way? The
best way to fix these problems is to install a "firmware" upgrade
onto your modem. These upgrades are often available for no cost on your
modem manufacturer's website, or at http://www.56k.com/links/Firmware_Updates/.
If you are unable to find your modem or computer maker on the list, or have
trouble installing the update, you should contact their technical support
3) How do I
tell my modem to connect using v.34?
Each modem chipset has a different way to do this. You should try an init
string from the following chart
Chipset Winmodem (HCF)
Chipset Hardware Modem
How do I use the init string in Windows
95/98/NT? Click on Start, Settings,
and then Control Panel. Then locate the Modems icon and double click on
that. A dialog box should appear that lists your modem. After making sure
your modem is selected, click on the Properties button. This will bring up a
window with some tabs at the top, the second one should be labeled
"Connection". Select this tab. In the bottom right hand corner
there is a button that says "Advanced". Clicking on this button
brings up a window with a box labeled "Extra Settings". Type the
init string for your modem into this box. Close all the windows by clicking
OK, and the change should be complete. After doing this, you should try to
connect. If your computer has trouble communicating with the modem, you
probably used the wrong init string. Remove it and try another.
init strings didn't work! What do I do now? You should try to disable
v.90 by adding some commas to then end of our access number. For example,
instead of dialing "
4) Can you
connect by dialing around your local telco loop?
If you continue to have problems, you may want to run a little test. If you
dial "1010321" and then "1231" and then our phone number
(long distance charges will apply) you will be dialing around the local loop
and your call will be placed on an "all digital, zero signal loss
network". If this solves your problems, you'll know right away that you
have a problem with the phone lines or equipment near your home or office
and should contact your local phone company for a resolution. In some remote
areas, there may be no resolution until the local phone company upgrades
their equipment. If this is the case, your only choice for a reliable
connection is to downgrade to v.34 in step 2.
5) Does your
modem pass the 56k line test?
Another test for testing local line conditions is to use the free 3COM
56k Line Tester. You can do this by using Hyperterminal and dialing into
847-262-6000 (long distance charges will apply). Use firstname = line,
lastname = test when logging in. This will run a brief test on your modem
and will give you a report of how your modem and phone line tested out.
6) Have you
adjusted your FIFO Buffers?
What's a FIFO Buffer? Your software allows you
to lower your FIFO Buffers in an effort to correct for poor line conditions.
How do I change it? Go to Start, Settings,
Control Panel. Double click on Modems. Select your modem and click on
Properties. Click the Connection tab and then the Port Settings button.
Lower the Receive Buffer and the Transmit Buffer.
7) Do you
have the latest version of Dial-up Networking for your computer?
If you are using Windows 98/ME , you should be fine.
If you are using Windows95, you can download the update from Microsoft's
website at http://support.microsoft.com/support/kb/articles/q191/4/94.asp.
