Ah. Yes, we used to call the 50-pin version a telephone or telco
connector because, well, that's where we used to find most of them:
going to a 5-line office phone, or on the side of a punch-block.

But HP-IB and Centronics printer connectors didn't have enough pins to
be called telco connectors. Besides, HP-IB used bigger, stackable
screws, and Centronics printer connectors had those ears. It wasn't
'til I saw the 50-pin Centronicsish SCSI connector that I started to
get confused.
