• Is the Online LED lit?

If not, check the coax connection at the Telephony Modem 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.

• Is the Telephone (Tel 1, Tel 2, Tel 3 or Tel 4) LED lit?

If not, phone service has not been provisioned 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

• Is the phone plugged directly into the Telephony Modem?

Make sure the phone is plugged into the port on the back of the Tele-

phony Modem labeled “Tel 1/2” for line 1, “Tel 2” for line 2, “Tel 3/4 for

line 3, or Tel 4 for line 4.

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.

• Is the Telephony Modem plugged into a wall outlet?

If so, unplug the phone connector at the back of the Telephony Port and

plug in a known working phone. If you now have dial tone, the problem

is with the house wiring. Contact your MSO or a qualiﬁed wiring techni-

cian to correct the house wiring. If you still do not have dial tone, con-

tact your service provider.
