Mystery Nubus Card - SCII RNIS MAC V1.1

[chrisdunderdale]

Hello,

I have a SCII RNIS MAC V1.1 card, pulled from a machine some time in the late 90s, and I can't remember what it did/was for!

Any ideas, much appreciated!

That's an ISDN card of some sort. Seems ISDN is known as RNIS in France.

ah yes ok - It has an RJ-11 and RJ45 connector on the back, so that makes sense. Are these of any use to anyone these days?

@Compgeke (and I) do have use for them

RJ11 would be for telephone passthrough to use one of the B channels for telephone. ISDN's really cool

what use do people have for these cards today? What can you do with them?

If you happen to be lucky enough to have a POTS emulator sitting around, you can connect the card up to that and run a real ISDN connection

Alternatively, if you have TWO of these cards, you should be able to connect them directly with a crossover cable. You might even be able to leverage such a system to spin up a software-driven POTS emulator using the ISDN channel (essentially, phone "passthrough" that really just connects to an internal Asterisk server).
