A telecommunication switch for operating in a CS-2 intelligent network architecture. The telecommunication switch comprises: 1) integrated service logic (ISL) objects that perform requested services; and 2) a service control function access manager object that receives a first service request and determines if one of the ISL objects can perform a first requested service associated with the first service request. The service control function access manager object, in response to a determination that none of the ISL objects is capable of performing the first requested service, transmits the first service request to a service control function object external to the telecommunication switch. The service control function access manager object, in response to a determination that a first one of the ISL objects is capable of performing the first requested service, causes the first ISL object to perform the first requested service.
