The cable modem further retains the cable modem to work with the DOCSIS 3.0 standard upon the condition that the primary channel and the subsidiary channels are all locked or retains the cable modem to work with the DOCSIS 2.0 standard upon the condition that the MDD message is not received or the subsidiary channels are not successfully locked.
