CableTelephone Service
The MXD is compatible with cable
telephone service. Verify that the unit is
connected properly and displays a green
STATUS light, and verify that the correct
dialing instructions and telephone
number have been programmed into
the unit. Then test the unit.
PBX
Confirm that the correct dialing
instructions and telephone number
have been programmed into the unit. If
this does not correct the problem, the
unit may require an analog line (e.g., a
fax line) to work properly.
VoIP
The MXD is designed to work with VoIP
systems. Check that the residence
power is on and that the Internet
provider is in operation. The MXD will
not function if there Internet provider is
experiencing an outage or if AC
power/backup power is not available for
the residence’s Internet equipment.

dial 9)
No
Yes
The Unit needs to be programmed to
dial a prefix. Call your provider for
programming.
Use monitor mode as described in advance troubleshooting techniques, or call your provider’s customer service.
