So, I guess the reverse would also be true, if the incoming feed was lost, then presumably the outgoing would be lost as well?
In which case what would happen?
If a station couldn't air a programme to the network due to a down 'out' line, would each company have to fill locally, or would someone like Thames provide a network filler?
Or, if there was plenty of time - get that VT
in a fast car to a neighbour region (Thames to Southern / Granada to Yorkshire etc) and get the programme to air that way?
My user name might look like Hatton Cross, but it's pronounced Throatwobbler Mangrove.
