So I have started the process of stripping down my Dell Optiplex G1 i recently acquired and it had this combo of ISA cards installed in the bottom. As it has come from a recycler i deal with there is no HDD or history about the unit itself - however i am intrigued as to the purpose of these cards...

Motorola DSP's, noise reduction?

Relay units?

I doubt that is SLI!

My assumption based on what i have seen and worked with in the past is that this is some kind of PABX or POTS interface or controller perhaps.

I haven't attempted to research the card yet as i figured it would be more interesting to show it on here and open it up to you all 😁

Dialogic make voicemail and IVR systems - the card with the DSPs probably processes compressed audio, the card with the relays switches the lines...
