As best I know here are some of the things to look at:
SW = Software
T2 = Tier Two
BNDL = Bundle
Based on that you put up, it looks like you are looking at the following:
If you saw "SW-T2C-VRTL-BNDL-P" and "SW-T2-NFS" I would extrapolate that you are adding NFS to a bundle.
There is now way of stating what the first one is, with out having access to customer edge or the vendors quote tool.
You need to go back to the vendor and figure out what is in the bundle that they are quoting.
Good luck.
