• If not, check to make sure the Telephony Gateway is plugged in and the outlet has
power. Use only the external AC power adapter (if provided) and power cord included
with the equipment.
•
If the LED is lit, go to the next step.
2. Is the Online LED lit?
•
If not, check the coax connection at the Telephony Gateway and the wall. Ensure they
are connected and tight. If they are and you do not have dial tone, contact your
service provider.
• If the Online LED is lit, go to the next step.
3. Is the Telephone (Tel 1 or Tel 2) LED lit?
• If not, phone service has not been set up on that line. Contact your service provider.
•
If it is blinking, there is a phone off hook somewhere in the house. Find that phone and
hang it up.
•
If it is lit, go to the next step.
4. Is the phone plugged directly into the Telephony Gateway?
•
Make sure the phone is plugged into the port on the back of the Telephony Gateway
labeled "Tel 1" for line 1, and "Tel 2" for line 2.
•
If so, try a different phone. Make sure the new phone is a working phone.
•
If a known good phone is used and you still don't have dial tone, try a different phone
cable. If a new phone and cable do not restore dial tone, call your service provider.
5. Is the Telephony Gateway plugged into a wall outlet?
•
If so, unplug the phone connector at the back of the Telephony Gateway and plug in a
known working phone. If you now have dial tone, the problem is with the house
wiring. Contact your service provider or a qualified wiring technician to correct the
house wiring. If you still do not have dial tone, contact your service provider.
