The common cable labeling follows THX standard.
In general, the scheme in the room follows our left-to-right-reading fashion, but groups left/right pairs
Left/Right 1/2 Center/LFE 3/4 Left Surround/Right Surround 5/6 Back Surround Left/Back Surround Right 7/8
For a better structuring of the normal surrounds and back surrounds, I often see
Lss for Left Side Surround and Lrs for Left Rear Surround
Note that Ls/Left Surround is for 5.1 systems, and Lss/Left side surround is for 7.1, as they do no carry the same signals. Still for a 7.1 system, physical wires should be labeled with Lss/Rss and Lrs/Rrs. For people with some basic knowledge about the difference between 5.1, 7.1 and Hifi/Home cinema, the common mix of labels should pose no problem, like SW, BSL, SL, SBL, RS, RRS.
