A service designer´s functional view of intelligent network

Ameritech´s view of IN (intelligent network) Release 0 is described, and some of the technical issues to be addressed as the intelligent network evolves over the time period 1991 to 1995 are highlighted. The service switching point (SSP), which resides in local or tandem switching systems, is a critical component of the IN architecture and provides functionalities required and used by the service designer. The IN Release 0 SSP-SCP (service control point) interface is the initial step in developing a flexible service-independent interface, enabling switching programmability for the intelligent network. Initial implementation is planned for the existing generation of digital switches, and IN will evolve to extend its usefulness to the service designer
