DSL connection offline?
The following troubleshooting steps (1-6) may require disconnecting the phone/phone line/filters in order to make sure all phone devices are correctly filtered.
The first step you want to do is check cables and filters.
- Confirm that all telephones using the DSL telephone number are connected to a DSL line filter (see illustration) and there is a strong dial tone present.
- If you are DSL Direct (no dial tone service) you do not require any DSLfilters. Some DSL Direct customers in California have Quick Dial Tone in order to dial 911. If you have a phone device connected to the DSL Direct telephone number, you will require a filter for that device.
- If removing the devices resolves the issue and you need the additional telephone devices, contact AT&T to schedule a dispatch.
The following troubleshooting steps may require disconnecting the phone, phone line, or DSL filters in order to isolate the DSL signal and restore a solid green DSL or Broadband light to the modem.
- If the DSL/Broadband light is still not solid green, plug the DSL modem directly into the telephone jack without a filter.
- Also try plugging the telephone cable in an alternate wall jacks.
- Verify that the telephone cable is in good condition (e.g., no worn insulation, no exposed wires, etc.); if available, swap out the phone cable to rule out a bad cable.
