Basic Functioning
After you turn on power to the modem, the following sequence of events should occur:

the self-test procedure is running (see
“The Modem’s Front Panel” on page 1-5 for an
illustration and explanation of the LEDs).
2. After approximately 10 seconds, verify that:
a. The Power LED changes color from red to green.
