The Connection Status page allows you to set the downstream frequency for the cable
modem. Configuring the downstream frequency enables the device to quickly obtain a
direct frequency lock with the CMTS upon bootup and helps to save several minutes of
scanning for an available downstream frequency from the CMTS.
