Usage Guidelines

Usage Scenario

By default, the packets carrying TOD information abide by the UBX protocol.

Based on the signal type of an external BITS clock, you can run the clock tod protocol command to configure the protocol type that the packets carrying TOD information abide by.

Precautions

The TOD protocols at both ends of the 1PPS+ToD signal of the external time interface must be set to the same mode. Otherwise, the 1PPS+ToD signal cannot be used.

After the clock tod protocol ccsa command is configured, the input and output signals of the TOD convert the second pulse status of external time signals to the clock class according to the ccsa standard.

Example

# Configure ccsa as the protocol type that the packets carrying TOD information abide by.
