Dial-up Error 680- Article no. 2104

Dial-up error 680 occurs when:

Modem is not hooked up to the phone line correctly
There is no dial tone
The modem drivers are not initializing properly to detect a dial tone on the line
Dial tone is non-standard (PBX), digital, or they must dial outside access code to get dial tone
There are additional services on the line such as voice mail, or hunt services which cause a non standard dial tone

Verify the modem is connected to the phone line
The phone cord is going into the correct jack on the modem (marked Line)
The phone line is connected directly from the modem to the jack and not into surge protectors, line splitter, etc.
Verify dial tone and plug a phone into the same jack the modem is using, listen for dial tone
P lug a phone into the phone jack on the modem; listen for dial tone
If dial tone isn't detected, refer customer to their local phone company

Office / Hotel / PBX

If you must dial a number to get an outside line, you are using a PBX system (often found in office buildings, hotels, corporate apartments)
With PBX phone systems, you may have to dial an outside access code to get a dial tone
Also, the dial tone may be a tone the modem cannot recognize; the wait for dial tone before dialing option must be disabled

Voice Mail

Check for voice mail and disable it before attempting a modem connection
You may add commas (,,,) after the phone number to disable voice mail
If none of the previous solutions solve the problem, please contact the modem manufacturer
