If I understand the situation correctly (I'm no NDS expert, so bear
with me, but I was in the middle of defining the prtChannelInformation
entry), the way the prtChannelTable is organized, your example would
break out into multiple prtChannelEntry objects. Each of these would
have its own prtChannelInformation value, and they might potentially
differ in other prtChannelEntry fields.
