Note 1: Your cable company may configure the Telephony Gateway to always display the
US/DS indicator in green regardless of the connection speed or swap the meaning (speed
indication) of yellow and green.

Patterns: Startup Sequence

The following tables show the Telephony Gateway light patterns during each phase of the
