Indicator Lights: Startup Sequence

The following table shows the Telephony Modem light patterns during each phase

of the startup sequence. There are two phases of startup; the Telephony phase and

the cable modem phase. Both are outlined below.

Note: The DS and US indicators ﬂash yellow during startup, and turn green if

the Telephony Modem establishes an ultra-high speed connection. For

some cable companies these colors may be reversed.
