A someone else pointed out, you found a list of requirements for the USA where their rules have to take into account their 'blanket' Class E airspace and the fact that many airfields in the USA aren't connected to AFTN and instead have their own system of forwarding plans from the closest ATCC or FSS (Flight Service Station).
That was part of the training for my instrument ticket, fly an instrument approach into a non towered field then call the FSS and file a departure IFR plan over the phone. IIRC I had 30 minutes from hang up to get in the air and make contact.
