the DS DOCSIS channel.
Note The DS LED blinks before the US (upstream) LED blinks.
The US (upstream) LED lights up and flashes when the cable
modem scans for a DOCSIS channel and tries to lock on an
upstream signal. The LED stays solid when it has locked on to the
US DOCSIS channel.
The Online LED flashes when the cable modem is establishing a
connection to the router. It stays solid when the cable modem is
synchronized with the router.
