Implementing ain concepts in an existing switching system

Lee Davidson; Eric Valentine

Ericssons Traffic Management System (TMS) embodies the basic principles and much of the functionality of the future widespread implementation of an advanced Intelligent Network (AIN). TMS introduces AIN concepts into the existing telephony network, thus giving service providers an immediate revenue-enhancing tool as well as a real-world proving ground for AIN principles. The first TMS release begins commercial service in 1990.
