They were modified telex system which were circuit switched devices - so
when ,message were sent there was a "copper loop" between device,IIRC
signalling was done via current not volts and so guaranteed messages.
The company I worked, one of their products was a compatible terminal-
final testing at airline meant checking failure tolerance - throw as
much volts and current until the device literally was burnt out.
