The call data is dialed by the caller and comprises a credit card or station number together with a PIN (Personal Identification Number) used by authorized callers in placing the special service calls. The data base system includes a memory table of authorized numbers to which the calls are charged and billed. The data base transmits CCIS direct signaling verification messages through the signal transfer system to the TSPS signifying the entitlement and nonentitlement of the caller to the call service. | |
