OK: QAM BCASTQAM1 172.16.4.201 is alive.

OK: BIG CVLab 172.16.4.101 is alive.

OK: TED dncsted 192.168.1.2 is alive.

Important: Non-responding QAMs may have an old CVT table retained in memory. If non-responding
QAMs do not become active, then the device may attempt to download software because it is receiving
conflicting information from a non-responding QAM. This may cause the device to download incorrect
software.
