Inter-network application VSC - A Vertical Service Code used to provid

12、e access to a feature or service that requires multiple individual networks to act upon the code in a consistent manner on a given call. The code must have the same meaning to more than one public switched telephone network on a single call. For example, a call originates from a LEC network, is deli

13、vered to an interexchange carrier, and is terminated on another network. An inter-network VSC dialed by the originating caller would be understood by each network involved with the call and acted upon within an individual network accordingly. Intra-network application VSC - A vertical Service Code u

14、sed to access a feature or service within an individual network providers network. The use of this code is internal to a particular network. It does not require a standard assignment, nor is it dependent on a standardized assignment process. Multi-network application VSC - A Vertical Service Code us

15、ed to provide access to a feature or service that is common across more than one network. Multiple networks use the same code to access the same service, i.e. there is no interaction between networks. This allows for consistent accessibility throughout the PSTN of a feature or service. For example,
