適用范圍：The Subscriber PIN Intercept (SPINI) feature enables a subscriber to restrict outgoing call origination usage of their mobile. The subscriber is required to enter a SPINI Personal Identification Number (PIN) authorization code (i.e., a subscriber-specific string of digits) in order to originate calls meeting a specified criterion (e.g., local call type). If the correct SPINI PIN authorization code (or, simply, PIN) is entered, call originations are allowed. If an invalid SPINI PIN is entered, call originations shall be given denial treatment (e.g., an announcement indicating the reason for denial). Calls so denied may, optionally, be logged.
