That means that the modem cannot detect the correct (or any) dial tone when it picks up the line. Connect a normal; telephone to the line and lift the receiver. If you hear a normal dial tone, then the line is ok. Ithat is the case, then the modem may be faulty. You could try atz command and see what happens. If it is on a pabx or fax machine or something, the dial tone may be non-standard and teh modem won't recognise it. In that case, consult the modem manual for the AT command that tells it to ignore dial tone and dial anyway. You may have to enter that command as well as teh correct command to store that setting, alternatively you can enter the commands as an initialisation string in whatever software you are using to dial.
Hope that helps.
Disconnect the telephone-cable from the computer's modem.
Does your telephone regain the dial-tone?
If so, then replace the computer's modem -- it is going "off-hook" as soon as you turn on the computer, not just when you try to use the modem to open a dial-up session.
This problem can
be due to the software not handling a certain dial tone rather than a
specific hardware fault. Around the world there is a variance in the
signal quality of the dial tone which causes a report of no dial tone
detection. Disable the dial tone detection to prevent the system from
trying to detect a dial tone.
Disabling dial tone detection for modems: Windows XP
Click Start
Select Control Panel
Click Switch to Classic View to change the control panel view
Click Phone and Modem Options
Select the Modem Tab
Select the installed modem (Example: Lucent Technologies Soft Modem AMR)
Click the Properties button
Select the Modem tab in the Properties window
Click Wait for dial tone before dialing to remove the check from the checkbox
Select the Advanced tab
Add X3 to the Extra initialization commands field in the Extra Settings box
Click OK twice
Select Switch to Category View to change back the control panel view
Close Control Panel
if this does not work trying re-installing modem drivers.
Typically, a fax machine is connected directly to a telephone wall jack with a known working connection. Try plugging the fax machine directly into a wall jack first and pick up the handset on the fax machine if it has one. You should get a dial tone. Then try to fax something to someone you know.
The machine can also usually be routed through the modem in a computer by connecting the "line" cord on the modem to the wall jack and plugging the fax machine into the the "phone" jack on the modem. You may need to install the software that came with the fax machine to get this to work.
If you have no dial tone, check the wall jack with a known to be working single line phone. If there is a dial tone, it's something to do with fax machine, the computer modem or the connections.
Some fax machines can take advantage of internet faxing through a cable modem or DSL connection. Check your manual for the options available.
Look at the log on your 4100. Select "keep log on restart". Look for log outs and about 4 steps down Log ins (mine were about 20 seconds apart). See if your modem reset (watch your lights) coincides with taking your phone off hook. Take phone off hook for about 20 seconds until you loose dial tone (mine would reset at this point about 50% of the time and show several log off-on in the log. My phone company tech (SBC/AT&T) said that there engineering department had them install some line equipment at drop site that caused this problem. If you can do something to force the reset, then you'll get some action by your telco. Otherwise the testing they do will not show a problem. If this does not work, contact your state PUC. Your phone company will be more cooperative when they are contacted by the PUC.
Error 680--- No dial tone
A) Test modem by dialling a number through HyperTerminal or phone dialler. This will test the Modem without using Dialup Networking.
B) Make sure you are using the correct and/or original cable. Some modems used specific wiring which is not compatible with standard modem cables.
C) Check that you phone line is working with a normal phone.
D) Make sure the phone line you are trying to dial on is not a non-standard line, this can cause problems also.
E) If all the above are OK then get a new modem or test in a different location.
All versions of Windows are affected by this error.
No dial tone: There are many possible causes of a No Dial Tone Error.
First,
try testing the modem's ability to detect dial tone and to dial by
using HyperTerminal with the direct to COM port connect method - see
Using HyperTerminal. If you give your modem an AT&FX1 command, and
then a dial command, dial-tone detection will be disabled; if you still
do not get dial tone, the modem may not be installed correctly
(especially if it is a PCI or soft-modem); or the cable from the modem
to the phone-line jack may be bad or installed in the wrong connector
on the modem - try another line cord, and make sure you are plugged in
to the LINE - not phone - jack on the modem. Plug a regular phone into
the phone jack on the modem and make sure it has dial tone. The modem
may also be defective. Many new modems come with an electronic circuit
instead of the traditional electro-mechanical relay used to take the
modem off-hook. Some of these designs are proving less reliable; often,
they will be 'stuck' in the off-hook position, so unplugging, the
plugging in the phone cord may give dial-tone. If this is the case, the
modem needs repair or replacement.
If the modem will blind
dial (x1), but not detect dial-tone otherwise, the problem is likely to
be in the proper selection of the Country in
Windows->ControlPanel->Telephony or in improper installation of
the modem or lack of support for your country in the driver you are
using. Check to see if there are updated drivers for your modem.
If
the modem dials properly with detection (x3) in HyperTerminal, but does
not detect dial tone when using DUNs, the problem may be DUNs (check
for upgrade or re-install) or the proper setup and modem selection for
the DUNs connectoid.
For Embarq telephone service customers,
this error can indicate that you have a message waiting in your
voicemail. Embarq changes the dial-tone sound to a "fast" busy signal
when a new message is present in your voicemail box. This "fast" busy
signal can confuse the modem into thinking there is no-dial tone
present on the line.
Yes.Get rid of it.I have a Satellite also and do agree configuration was dodgy at first but the range in Wi-fi was not even 50 ft. as opposed the 100 ft. promised.But finally,after it shorted out my dial tone like most other 6520's I just went back to my trusty speedstream 4100.Good-luck.
