TP ---
WHAG ( Wild Hairy A** Guess) as I didn't invent it, but 13 CO lines and 1 ICM. ??? :rofl: :dance: :idea:
Actually, check your manual --- so many slots were wired for CO lines, some have to be strapped for other use --- maybe --- depending on the manufacturer.
Normally factory wiring is connected on the bottom of the 66 block lug. WECO, ITT, everyone seemed to do it that way. Field installed wiring was on top.
The 66-blocks are for termination of the rack mounted card slots. Most installers would extend the wiring to outside the KSU onto blocks to do the x-connects, etc., to make maintenance easier.
But back to your question, ITT called their version a 512 but it was wired for 13 COs. WECO had a later version called the 513 (totally different configuration) with a 514 adapter which then became a 515 (or could be ordered as a 515). The 513 was only good for eight COs without the 514. (If my memory isn't too bad.)
TP, have fun and don't forget to get a butterfly tool for your museum.
