repl-qam - slot 3, port 6, chan 1 (config-qrg)# no replicate-qam Qam-red3/21 Removing replicate from the group repl-qam - slot 3, port 4, chan 1 repl-qam - slot 3, port 5, chan 1 repl-qam - slot 3, port 6, chan 1 (config-qrg)# exit (config)# interface Qam-red3/21 (config-subif)# cable downstream rf-power 310 (config-subif)# exit (config)# cable qam-replication-group 1 Edit qrg - group number 1 repl-qam - slot 3, port 4, chan 1 repl-qam - slot 3, port 5, chan 1 repl-qam - slot 3, port 6, chan 1 (config-qrg)# replicate-qam Qam-red3/21 repl-qam - slot 3, port 4, chan 1 repl-qam - slot 3, port 5, chan 1 repl-qam - slot 3, port 6, chan 1 (config-qrg)# end Mute and Unmute a QAM Muting (shut down) and unmuting (no shut down) a pilot carrier performs the same operation on all its corresponding replicates The following example shows how to mute and unmute a pilot: (config)# interface Qam-red3/11 (config-subif)# cable downstream rf-shutdown (config-subif)# no cable downstream rf-shutdown The following example shows how to mute and unmute an individual replicate carrier This administratively shuts down the QAM Note The rf-shutdown command cannot be used on a replicate QAM (config)# interface Qam-red3/21 (config-subif)# shutdown (config-subif)# no shutdown Mute and Unmute a Port We recommend that you do not mute (shut down) a port that contains QAMs that are part of QRG If the pilot QAM port is muted, all its corresponding replicate QAMs on other ports are muted 15

The following example shows how to administratively shut down or no shut down the port Note The rf-shutdown command cannot be used on a replicate QAM (config)# interface Qam-red3/1 (config-int)# shutdown (config-int)# no shutdown Not Recommended ASI Monitor Configuration on a Replicate Port We recommend that you do not configure Asynchronous Serial Interface (ASI) monitor on a replicate port If it is configured, a warning message is displayed and unexpected system behaviors may be observed Default Configuration on a Pilot/Replicate Carrier or Port We recommend that you do not to use the default configuration command on a pilot or replicate carrier if it is for remote learn DEPI If the default command is used, you cannot reconfigure the QRG after the default configuration of the pilot or replicate channel 16
