3 PC Link Status

- Indicates that the cable modem is

connected to the Ethernet card in your computer. This light
is solid green when this link is established and your
computer is on.

4 PC Link Activity

- Indicates that data is being transmitted

to or from your PC over the Ethernet port. Flashing orange
indicates traffic. This LED should blink when data is being
transmitted or received over the Ethernet port.

Upgrading to CMX Functionality

If your BSP decides to upgrade their service to two-way
functionality, they may automatically upgrade your TMX to
CMX functionality. You will be alerted if this happens. In
this even, you will want to download our 3Com U.S.
Robotics Cable Modem CMX documentation at:
