     I visited the Mahwah NJ hub in the early 1970s.
They were using UNIVAC 494 real time mainframe computers for
switching.  The international gateway for message traffic across the
Atlantic was there.

    The amount of traffic was tiny by modern standards.
Undeliverable messages popped up on the screen
(a UNISCOPE 300) of a telegram operator. About once
a minute, she had a message to redirect. That's
out of all transatlantic traffic.

Here's the console of a UNIVAC 494 system.
The UNIVAC 1108 used the same console.

Inside that is a custom variant of a Model 35 typing unit.
6-level, no shifts, FIELDATA code.
Keyboard was electronic and built by UNIVAC.
