• Is the Telephony Modem plugged into a wall outlet?
If so, unplug the RJ-11 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.
