Possibly, after all that's what the BBC regions had/have, along with a cue dot and 'Presfax'. I don't think ITV had a similar network of tallback/comms circuits - they had the red phone network, however that worked.
I wonder if, when necessary, Channel 4 liaised with the nominated contractor (THS/LWT) who passed on the info to the other regions via the red phone? I’m not aware of them having any talkback or direct voice link to the regions. That said, Tony Currie (presumably in his STV days) contacted C4 pres to advise them of a problem, so maybe C4 would call regions direct too. I can’t see them wanting to make 13/14 phone calls though to say “break 17 will be 30 seconds later than planned”.
Could the ITV regions have received a voice telling them how long til the next ad break, as well as the cue dots?
