I believe, and don't quote me on this, but the term "biscuit jack" referred to the one-piece surface jacks that were made by Communications Apparatus Corp. (CAC; later Siecor) that had the corners chopped off so that they were nearly round in shape. They did almost resemble the shape of a biscuit. They were pretty stupid looking in my book, but Contel used them everywhere around here.

Oh and while we're on the subject, the Bell guys around here referred to B wire connectors ("beenies") as mouse rubbers.
