This European Telecommunication Standard (ETS) defines the requirements for the handling of network addresses for the identification of entities which use telecommunication services offered by Private Telecommunication Networks (PTNs). The standard covers numbering, including the requirements for the support of a Private Numbering Plan, and the support of subaddressing. The use of more than one PTN numbering plan in a single PTN is excluded from the scope of this ETS. However, this ETS does not exclude the possibility that physical equipment may be part of more than one PTN.
