Country Selection Functional Descriptor.
The Country Selection functional descriptor identifies the countries in which the communication device is qualified to operate. The parameters of the network connection often vary from one country to another, especially in Europe. Also legal requirements impose certain restrictions on devices because of different regulations by the governing body of the network to which the device must adhere. This descriptor can only occur within the class-specific portion of an Interface descriptor and should only be provided to a master Communication Class interface of a union. The country codes used in the Country Selection Functional Descriptor are not the same as the country codes used in dialing international telephone calls. Implementers should refer to the ISO 3166 specification for more information.
