I take your point, of course. But there *were* other regional devices back in the Bad Old Days. Each country had its own (usually monopoly) telecom carrier(s), and very many of those had non-standard (or rather, local standard) interfaces of their own invention. So in the 1960s-70s there were endless regional feature codes for the 37x5 comms controllers to connect to these different lines. Even somewhat more recently, North America used the "T1 interface, at 1.544 Mb/s which can carry 24 voice calls at 64 kb/s, while Europe and most of the Rest Of World (ROW) used "E1" at 2.048 Mb/s to carry usually 30 phone channels. T1 and E1 also have different and incompatible protocols at several levels, so there was no question of just plugging in like an Ethernet cable, and each end negotiates the best connection. Very amusing to see an IBM box with a connector labelled "customer equipment" plugged into a Telco box connector also labelled "customer equipment". All in one's point of view. I digress, but it's Friday.
