Question: What is the maximum total amount of free format data that the gsmSCF can send per leg for completion of a logical call record, and how can it be transmitted?
Option 1: 80 octets per leg, which must be sent in a single Furnish Charging Information (FCI) IF
Option 2: 160 octets per leg, but only through a single Furnish Charging Information (FCI) IF transmission
Option 3: 160 octets per leg, which can be sent in one or more concatenated Furnish Charging Information (FCI) IFs
Option 4: 320 octets per leg, divided into two separate transmissions of Furnish Charging Information (FCI) IFs
Explanation: This is the correct answer because the gsmSCF can send a total maximum of 160 octets of free format data per leg for completion of a logical call record, achievable through either a single FCI IF or multiple concatenated FCI IFs, offering flexibility in data transmission.
