It turns out the CNF cards don't count towards ports-- so I have 540 ports in the system.
I filled in empty spaces with "dummy" extensions, and even had to create two dummy lines on GS cards (which then I busied out with Line Maintenance), but for now there's no worry that I'm "over" capacity.... I might move card 48 into slot 32, to see if a card will work there. Right now, Stn 48 has 12 DVAs on it, so I'll probably move it late at night.
