Question: What is the significance of the value '65535' for the 'Length of private extension' parameter in a Charging Data Record (CDR) file header?
Option 1: It indicates the maximum allowed length for a private extension field, which is 65534 octets plus the 2-octet length parameter.
Option 2: It signifies that no private extension field is included in the CDR file header.
Option 3: It represents the default length for all private extension fields in CDR file headers.
Option 4: It is reserved for future extensions, specifically for private extensions exceeding 65534 octets.
Explanation: The value '65535' (with all bits set to '1') is explicitly reserved for future extensions, accommodating potential private extensions that would exceed the current maximum length of 65534 octets, excluding the length parameter itself, showcasing a forward-thinking approach in the CDR file format design for flexibility and scalability in telecom charging management systems.
