Suggested Action
Wait until the cable voice adapter finishes its
power-up sequence. If the blinking is
continuous, contact your service provider.
Check power connections.
Check the outlet or try another one.
Replace the power supply.
This is normal behavior when the Ethernet
interface is not used.
Verify the PC is powered on.
Reseat the Ethernet cable at both ends.
Verify that the Ethernet cable is the correct
type (straight-through or cross-connect) for
the equipment used. If using an Ethernet hub,
try connecting a PC directly to the cable voice
adapter using a straight-through cable.
Install the proper driver and TCP/IP software
for the Ethernet card and verify that DHCP is
enabled on the PC.
Replace the Ethernet card.
This is normal behavior when the USB
interface is not used.
Verify that the correct cable (host-device
cable with type "A" and type "B" connectors,
maximum length 5 meters) is being used and
is firmly inserted in both connectors.
Install the USB software according to the
instructions in the booklet that accompanies
the USB driver CD.
Windows 95 and Windows NT do not contain
support for USB networking. Install Windows
98, Windows 2000, or Windows Millennium.
