Double Current signalling

Probably a question for Fred, but very happy for anyone to comment.

Attached is a small section that describes how the UK telex system interprets the various states of the S and R wires on telex lines - this I think is important for UK "FSG" to work with I-Telex.

Sadly programming is well beyond my grasp - I am still developing a single to double current converter with Jeff, but would also still like to see a direct implementation within I-Telex.

What other areas of development are a problem from making this easy to solve?

Hi Sean,
fine document, this helps a lot.
Questions: What's "S.L.C." and what's VF circuit?

Hi Fred, VF is almost certainly Voice Frequency - this would apply to Telex circuits that work on conventional phone lines I think.

SLC - a very good question!

can you PM me your email address, and I can send you the full document - not for public eyes unfortunately

SLC - Station Line Circuit. From my understanding this can be ignored for the purposes of I-Telex
