I am looking for help understanding Trunking Tables.

As my local system is being rebanded (2 sites done, 39 to go) I am working with my GRE scanner to enter the custom Trunking Tables. There is another thread that covers teh exact values, but I would like to understand what they mean.

The table below is what I would like clarification on...
