TEC has exempted till June 30, 2023 or till further orders for a few parameters from Precision Timing Protocol ER as there are no labs as yet designated in India to carry out testing which are as follows:
- Max Peak Voltage for 10 MHz Interface
- Min Peak Voltage for 10 MHz Interface
- Profile for frequency synchronization
- Profile for time and phase synchronization with full timing support
- Profile for time and phase synchronization with partial timing support
- Pulse Shape for 10 MHz Interface
- Pulse Width for 1 PPS Interface
- Rise Time for 1 PPS Interface
