your 1st card is the old loop 1 terd your supporting, the next card is a network card, has 2 places to plug a cable in the front, if your uising both, that gives you loop 4 0 and 4 1, if your using just j2, it's for 4 0. the next card looks like your pri card (loop 12) then your 1st conf/tds. . the next shelf, 0,1, starts with another network card, using post 16, because that is a network card it takes slots, 15,16,17, and 18. it's not a double wide card, but it takes 4 slots just the same, in load 97 (supl and xpe) the phyiscal location is defined as left or right hand side of those two slots. the next 4 cards i see are both dual pri, 20,21,24 and 25. i would have put those next to each other, and saved 24 for a possible network, the next card looks like a misp, (bti switching, vidio conf).. the last card in that shelf would be the confer/tds. that will give you a fair start, when i 1st started, i came in off hours and disl'ed loops and conf cards to locate the counts. it wasn't after an install that it made semse. remember, just to make it a liitle more fun, msdl cards can plug into any slot, now you have to tell software which network, but the device number is a switch setting only. don't let those confuse the issue, i usually build one loop on the right and the next on the right, leaving a otherwise unusable space in my shelf, the msdl only get power off of the backplane
