Indicator Lights for the WTM552G/H Models
The Touchstone Telephony Modem has fourteen indicator lights to assist in trouble-
shooting.
Wiring Problems
If the Telephony Modem begins flashing all its lights for more than 10 seconds, this
indicates a problem with the telephone wiring — the red and green wires may be
shorted (touching), or there may be undesired voltage on the lines. If this pattern
persists for more than 10 seconds, disconnect the telephone lines from the Tele-
phony Modem, then call a wiring technician for assistance.

Using the Reset Buttons
Use the
Router Reset
button to reset the Ethernet and wireless connections with-
out affecting the cable or telephony connections. You may need to reset the router
if you are having problems connecting to the Internet, but the phones are working.
To reset the Telephony Modem to factory defaults, hold the
Router Reset
button
for about 8 seconds.
Use the
TM Reset
button, on the back of the Telephony Modem, to reset the mo-
dem as if you power cycled the entire unit. The phones will be out of service until
the Telephony Modem finishes reconnecting to the cable system. You may need to
reset the Telephony Modem if you are having problems connecting to the Internet
or with the phones. This button should be used rarely.
The
TM Reset
button is recessed to prevent accidental resets. Use a pointed
non-
metallic
object to press this button.
The diagram to the left shows the location of the Reset buttons.
