This post should be moved to 1A2.

Real quickly though.

It is a semiautomatic ringdown card. Only 1 required per circuit. Automatic at the distant end, manual at the local side.

It's a 20 pin card, so you need a 259 or 359 panel. I don't think the WE 551 or the ITT 601 has 20 pin slots. (I don't know what a 611 is)
