Question: What happens to non-completed free format data in a logical call record when a new Functional Charging Indicator (FCI) operation is received to overwrite it, and what is the maximum additional free format data that can be sent by the gsmSCF per leg afterwards?
Option 1: The non-completed data is appended to the new FCI operation, with no limit on additional free format data.
Option 2: The non-completed data is discarded, and the gsmSCF can send another 160 octets of free format data per leg in one or more FCI operations.
Option 3: The non-completed data is stored separately, and the gsmSCF can only send an additional 80 octets of free format data per leg.
Option 4: The logical call record is deleted, requiring a new initial FCI to start anew, with the standard 160 octets limit applying from scratch.
Explanation: This correct answer reflects the specified behavior in the context of Customised Applications for Mobile network Enhanced Logic (CAMEL) Phase 4. When a new FCI operation is received to overwrite non-completed free format data, that existing data is discarded. Following this, the gsmSCF has the capability to transmit up to an additional 160 octets of free format data per leg, split across one or more subsequent FCI operations, adhering to the defined maximum limit for efficient network management and data handling.
