Experiences in prototyping the intelligent network

The authors provide an update on the intelligent network (IN) testbed under development by GTE, discuss their experiences in prototyping INs, and present some plans for the testbed. The testbed includes prototypes of AIN switch capabilities (on a GTD-5/sup 1/ EAX switching system), service logic execution environment, service creation environment, intelligent peripheral, and m-specific operations support systems. The testbed, originally based on the advanced intelligent network (AIN) release 1 architecture, as proposed by Bellcore, has evolved with the industry and is maintaining compatibility with AIN releases 0.1 and 0.2. Nonetheless, as the call model implemented in the first phase of testbed development represented a substantial subset of the AM release 1 call model, the testbed provides richer functionality, particularly for mid-call services, than other flavors of INs under consideration by the industry.<
