Indicator Lights for the TG1682
The Xfinity Telephony Gateway has several LED indicator lights to assist in trouble -
shooting.
Wiring Problems
If the Telephony Gateway 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 Gateway, then call a wiring technician for assistance.
Patterns: Normal Operation (LAN and Telephone)
The following table shows light patterns for the Ethernet, MoCA and wireless LANs,
