Homer,
Take a look at this link from Dolby Labs:

As I stated earlier, Dolby intends the primary surround speakers to be at the side location. So, in DD 5.1, the speakers are L, C, R and L side, R side. For 6.1, you add a center back speaker and for 7.1 you add a L back and R back.
In the instance of your Lexicon, they went a step further and actually labeled the surround outputs as "side", which is where Dolby recommends the primary surround speakers be placed.. However, in my experience, this is not typical. Typically HT receiver manufacturers label the default surround outputs as "surround" L and "surround "R". This would correspond to the ones marked "side" L and "side" R on your Lexicon.
If the receiver supports additional channels of processing/amplification, they are typically marked as "surround back" for 6.1 channel receivers and "surround back L" and surround back R" for 7.1 receivers.
Sorry I've replied so late, but this may also help folks who search the topic in the future.
Enjoy,
TIC
