The table describes relationships between destinations
defined in the chmgrODescrDestinationTable, channels and
source routes. To make a connection to a destination 1+1
protected, create two rows representing the two channels in
the table. Note that this is only allowed if the bit
allowProtection(5) is set in chmgrODescrCapabilities.
If no conceptual row exists for a destination, it is assumed
that there shall be only one channel to the destination and
that no source route is shall be used.
A channel to a destination may have its route through the DTM
networks defined by one or many source routes. If multiple
source routes are defined, any one of these source routes is
chosen when the channel is established.
