What Does a Flashing DS Light on an Arris Touchstone Telephony Modem Mean?

The standard Arris factory settings for the indicator lights are the yellow light at the DS position, which indicates that the modem is connected to the Internet at high speed, and the green light at the DS position, which indicates an ultra-high speed Internet connection. It is possible that individual cable companies can reconfigure the lights to show green regardless of Internet connection speeds or swap the meaning of the green and yellow lights.
