Telecommunications licences and rights: IRUs: particular points
International private leased circuits
An international private leased circuit is a circuit leased from an international facilities operator that crosses one or more international boundaries. If it is an IRU (or a right derived from such a right) then the rules in FA00/SCH23 will apply.
If rights are to use only the ducts then they are not rights to use a telecommunications cable system and are not within the rules in FA00/SCH23.
