2.5 Frequency Channel
The cable modem will automatically search for the active channels, will go through a
handshake with the CMTS, will be told all the parameters it will need to join the
wireless network and will be authenticated/authorized to join.
2.6 Modem http Interface
The modem status can be determined by the LEDs and by a browser interface.
The typical modem LEDs and their use are:
Power: ON = power OK
Cable: ON = ranged & registered with CMTS, blinking= in process
LAN: ON = connected
USB: ON = connected [some modems have both USB & LAN connectors]
Activity: blinking = data (transmit or receive)
The browser interface is available on some modems and contains more information.
The typical instructions in the user manual are to follow these steps:
Connect a PC to either the modem’s USB or the Ethernet interface
Launch the PC’s browser, such as Microsoft’s Internet Explorer
