We are planing on swapping out a Samsung OfficeServ 500 and trying to find documentation on the card PinOuts. More specifically the 16SLI and 16MWSLI

For example 16SLI sounds to me like an Analog card for 16 lines (FXS) I was assuming 1-16 but testing the pins directly on the card, I get dial tone on all the pins. The first 16 produce extensions numbers while the rest came back "blank"

Does this make sense?

Any help would be appreciated!
