Question: What determines the timer tolerance for testing in a telecom network, when not explicitly specified in a test document, with a base value of 10% or an alternative calculation involving TTI and a delta time constant (tdelta of 55 ms)?
Option 1: The timer tolerance is always fixed at 5%, regardless of the calculated values.
Option 2: It's the lesser value between 10% and the sum of 2 TTIs plus tdelta (55 ms).
Option 3: The network operator's discretion, which can vary by region.
Option 4: The greater value between 10% and the sum of 2 TTIs plus tdelta (55 ms).
Explanation: According to telecom testing standards, for consistency and reliability across different networks and devices, timer tolerances are standardized. When not explicitly overridden by a specific test's requirements, the tolerance is dynamically determined by taking the greater value between a flat percentage (10%) and a calculation incorporating the transmission time interval (TTI) plus a constant delta time (tdelta of 55 ms), ensuring flexibility with varying TTIs while maintaining a minimum tolerance level. This approach balances precision with adaptability in network testing scenarios.
