My Zoom ADSL modem does not sync with my ADSL service provider. What should I do?

1. Is there a line filter used on the same telephone line as the Zoom ADSL Modem? If so, the modem will not be able to sync with the service provider.
2. Are the Zoom ADSL Modem drivers installed correctly?

If the problem still persists, please answer/verify the questions below and submit the information to Technical Support by clicking here. If you are unsure of the answers to questions 1 - 7, contact your ADSL service provider.

1. What ANNEX (A, B, or C) does your Service Provider support?
2. What type of DSLAM (Lucent Technologies-based, Globespan-based, etc.) is used to connect to your modem?
3. What is the DSLAM chipset (ADI, GSI, Alcatel, etc.)?
4. Which protocol (RFC 1483-LAN, RFC 2364-WAN, ATM, RFC 2516-PPPoE, etc.) does your service provider support?
5. What is the VPI (Virtual Path Identifier) number (e.g., VPI=0)?
6. What is the VCI (Virtual Circuit Identifier) number (e.g., VCI=35)?
7. Did the Service Provider activate your ADSL line/service?
8. When the telephone line is plugged into the Zoom ADSL Modem, does the Data light(LED) flash and then turn solid? This process normally takes 30 seconds to 1 minute.
9. What is the version of the drivers? This is found under Control Panel | Zoom ADSL Modem | System Info tab.
