Abstract
A communications network system having an advanced intelligent network (AIN) controlling the system provides narrowband and broadband communications to customer premises. The system includes a narrowband network for narrowband communications including at least one signal switching office and a signal system. The signal switching office routes narrowband calls and detects an outgoing narrowband call from a customer at a customer premises and also detects dialed digits corresponding to such outgoing narrowband call. A broadband network for broadband communications is connected to video equipment at the customer premises. The video equipment includes a video display and is connected to the broadband network via an addressable settop box. A services control point in the advanced intelligent network is operative to perform network service logic programs for routing narrowband communications in the narrowband network. At least one of the network service logic programs is responsive to a query from the at least one signal switching office resulting from detecting the outgoing narrowband call and also detecting the dialed digits corresponding to that call. The service logic program instruc…
