[GreenKeys] Telex Circuit Needed

[Lester Veenstra]

Is this a private line (point to point circuit) or one interconnected with
the real world telex network.  And what Common Carrier in the US still
offers actual DC Current loop telex service as opposed to the voice channel
dial up TWX.

Harry's message prompts me to ask a question of the brain trust here on
Greenkeys.

As Harry states, Telex is still used in the shipping industry.  And of
course KPH had several Telex lines serving the station, driving 60ma and
later 20ma loops.  

My research shows that it's no longer possible to order the classic Telex
line we'd need to reactivate true Telex service art KSM (the call of the
station now operating using the KPH facilities).  So my question is this:

Is there a way to simulate Telex service using other technology such as a
dial up modem driving a 60ma loop or other arrangement?

Ideally we'd be looking for full answerback, etc., just as was the case with
the original Telex.

One problem we have at the receive station (where the Telex service would be
put in place) is that we have no Internet connection beyond a slow, rural
dial up line.

All suggestions appreciated.
