Question: What happens when a User Equipment (UE) encounters multiple occurrences of the 'DTMF Control Digits Separator' in an Abbreviated Dialling Number record, in terms of sending DTMF digits to the network?
Option 1: The UE sends all DTMF digits immediately after the first separator, without any additional delays.
Option 2: The UE ignores all but the first set of DTMF digits, pausing only once before sending the initial set of DTMF digits.
Option 3: For each subsequent occurrence of the separator, the UE pauses for an additional 3 seconds (± 20%) before sending any further DTMF digits.
Option 4: The UE requires manual intervention to proceed with sending DTMF digits after encountering multiple separators.
Explanation: This is because, according to the specified behavior for handling multiple 'DTMF Control Digits Separators', upon each subsequent occurrence of the separator, the UE is required to pause again for a specified duration (3 seconds ± 20%) before transmitting any additional DTMF digits. This ensures a structured and timed delivery of DTMF inputs in scenarios where multiple sets are predefined with separators.
