Support inputting 1 way of GPS clock signals for GPS timing.
Support inputting/outputting 2 ways of 1PPS+TOD level signals, with the interface type
of RJ45.
Support inputting/outputting 1 way of 1PPS signals, which is configurable, with the
interface type of BNC.
Provide an E1 external clock interface in the form of RJ45. It inputs/outputs 2.048 MHz
or Mbit/s clock signals. The electrical features comply with ITU-T G.703 standards.
Support IEEE 1588v2 and thus support receiving and processing IEEE 1588 v2 packets;
support OC master/slave clock mode, BC clock mode, and TC clock mode.
Support hot swapping.
