What Type of Cards Are These?

[ccastillo]

We have two cards in our PBX (Option 61C) that are labeled CONF/TDS NT8D17FA. What are they for? Nothing is connected to them.

Does anyone know where I can get documentation on them?

Thanks In Advance,

I had the air conditioning go out in the switchroom of one of my remote Opt11c's in Nashville one time and all of the TDS ports locked up in the switch, so it stuck in my head.
