[GreenKeys] TWX-TELEX history

[Jeffrey D Angus]

Indeed an interesting read, thank you Henning.

Looks like the big difference between switch telephone and switched
teleprinter equipment was the end-to-end continuous copper
connection. Excluding the use of tape equipment in the central office.

Towards the last periods of operation of the Telexs and TWX networks,
didn't they switch over to modems, so they could send the data over
traditional voice circuits?
