10-MHz and PPS ports

 

The 10-MHz and PPS input clock connectors are used to connect to an external clock source, such as a GNSS receiver with precise timing outputs. The 10-MHz and PPS outputs provide debug information for the Synchronous Ethernet and IEEE 1588 timing circuitry.

The LEDs on the BITS port are used to convey the status of the T1/E1 BITS timing interface. Table 1 describes BITS LEDs.
