8.1.3 Set the Downstream Frequency (optional, but recommended)
By setting the downstream frequency received by the modem from the ARCell Transceiver,
modems will correctly center its downstream frequency. If this is not set, the modem may be
slightly off frequency resulting in poor performance.
Select the Downstream Frequency button and enter the center downstream frequency in
Hertz, then click Save.
8.1.4 Assigning an Upstream (optional, but recommended)
Assigning the modem to a specific will prevent the modem from locking on the wrong
upstream channel. When a modem can see multiple upstream channels it does not
automatically pick the best one. Setting the upstream ID will guarantee that the modem will
never lock on a different upstream channel
Click on the Upstream Channel ID button and enter the upstream ID that you want the
modem to be on, then click Save.
