Notes:
You need an optional cable signal splitter and additional standard RF coaxial
cables if you want to connect a VCR, a Digital Home Communications Terminal
(DHCT) or a set-top converter, or a TV to the same cable connection as your
cable modem.
If your product supports telephone service, cables and other equipment needed
for telephone service must be purchased separately. Contact your service
provider to inquire about the equipment and cables you need for telephone
service.

Front Panel Description
OL-31573-01 5
Front Panel Description
The front panel of your cable modem provides LED status indicators that indicate
how well and at what state your cable modem is operating. See Operation of Front
Panel Indicators (on page 21), for more information on front panel LED status
indicator functions.
1POWER—ON, power is applied to the cable modem.
2DS—ON, the cable modem is receiving data from the cable network.
3US—ON, the cable modem is sending data to the cable network.
4ONLINE—ON, the cable modem is registered on the network and fully
operational.
5LINK—ON, a device is connected to the Ethernet port. BLINKING indicates that
data is being transferred over the Ethernet connection.
6TEL1—ON indicates telephony service is enabled. Blinks when line 1 is in use.
OFF indicates that phone service for TEL 1 is not enabled.

Chapter 1 Introducing the Cable Modem
6 OL-31573-01
7TEL2—ON indicates telephony service is enabled. Blinks when line 2 is in use.
OFF indicates that phone service for TEL 2 is not enabled.
8BATTERY (optional model only)—ON indicates the battery is charged. Blinking
indicates the battery charge is low. OFF indicates the unit is operating from
battery power, the battery charge is depleted, or the battery is defective or
missing.
Notes:
After the cable modem is successfully registered on the network, the POWER,
DS, US, and ONLINE LEDs illuminate continuously to indicate that the cable
modem is active and fully operational.
The high-speed data operation is disabled when operating on battery power;
only the telephone service (if available on this model) is active when operating
on battery power.
LEDs may behave differently when the cable modem is running on battery
power (without AC power). Most LEDs are disabled if the unit is operating on
battery power. In this mode, the POWER LED blinks to indicate that the unit is
operating under battery power.
The cable modem should only run on battery power when AC power has failed.
If the POWER LED indicates that the unit is running on battery power, but the
AC power has not failed, verify that the power cord is plugged into a working
AC outlet.
