SV9500 MWI... Still only SDT, or is FSK available now?

In 2015 with an AVST CX-E voicemail upgrade I switched all the 16LCBY SP3396 A 2A cards in our SV8500 to stutter dialtone and turned off the previous 90V MWI system. The latest circuit card manual I have is when the SV8500 was still an IPX, with no mention of FSK MWI available on any analog cards. Looking at newer 3rd party analog sets though, the push seems to be to FSK signalling rather than SDT for MWI.

If we upgrade the SV8500 to SV9500, does NEC have analog cards that support FSK for MWI now ?

Thanks!
