other systems need to be bonded per 250.94.
the Leviton structured media systems , as far as i can tell with those i've installed, seem to be an'inside'
goodie placed by the panel.
These 'other systems' (read~tele,cable)
that usually come from the street and end up near the meter location usually expect a means to bond there (so the service dude doesn't need to come in?)
The NEC changed a cycle or two ago to express this, many started simply extending a piece of bare cu out of meter bases on all-pipe services to comply
(can you believe a poco guy said to me that my GEC wasn't long enough)
and yes, i use the green G-screw to make a small piece of bare cu into the panel 4 square to terminate with the EGC there also....
when in doubt, ground it!
