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!

The pin outs for the 16(mw)sli are the same as the 16dli if you have those.
They use a 25 pair amp champ which is either terminated into blocks on a telco frame, or direct into a patch panel.

Thank you for confirming they are alike. Is there suppose to be dial-tone on pair 17?

To clarify on 17,18,19,20,21,22, etc.. I was getting dialtone, I thought only on the first 16 should there be dialtone..

From memory every 3rd pair was skipped on the 25 pair.
Ie p1, p2, p4, p5, p7, p8 and so on.
You need to find an idcs500 or os500 manual and look in there.
There is no manual specific to those cards

There is. As Nameless said, the pinouts on a 16 port SLI card is two pairs, skip a pair throughout the block. So pin 17 is port 12.

PINS PORT
1,2 1,2
4,5 3,4
7,8 5,6
10,11 7,8
13,14 9,10
16,17 11,12
19,20 13,14
22,23 15,16

Carl, remembering why I hate iDCS... and formatting in this post

@Carl @Nameless, Thank you for the updates- So if I am understanding you the below mock up would be correct?

(I did find a manual but no mention of layout Link)

Perfect! Stolen!
