[GreenKeys] Telex Network undergoing a revival (UK)

[Jack]

Larry,

I assume the UK folks are using TELEX signalling protocols
as a means to utilize an existing backbone network. A neat idea.
Unfortunately, our networks are long gone...most of the internal
TELEX systems in the US were ancient when they were phased
out in the 70's (I think Western Union still had terminal centers
with vacuum tube technology). 

I worked on some low-speed data/alarm applications in the late
1970's while with the Bell System in New York. But I think
that those kinds of systems were very short-lived due to the
quick growth of higher speed networks (packet and so on). The
IBM PC pretty much killed any other types of proprietary
systems. 

Many of the alarm systems are now RF-based using packet
protocols.
