Indicator Lights for the WTM552A/B Models
The Touchstone Telephony Modem has 13 LEDs to assist in troubleshooting.
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.
