<p>In a telephone network, customized advanced intelligent network (AIN) services are provided to standard IN/1 '800' service customers. An IN/1 service switching point (IN/1 SSP) (130) receives a call directed to the standard IN/1 '800' service customer (112), and generates an '800' query to an '800' services data base (156). An '800' service control point ('800' SCP) (150) generates an '800' response containing a carrier identification code, and the IN/1 SSP routes the call via a trunk group designated by the carrier identification code. An AIN-equipped service switching point (AIN SSP) (126) then generates an AIN query to an AIN service data base (174). In response, an AIN-equipped service control point (AIN.SCP) (170) executes AIN service records corresponding to the standar IN/1 '800' service customer to generate an AIN response containing call processing instructions. The AIN SSP (126) then uses the call processing instructions to complete the call.</p> |
