the time to the ONU through the GPON line. After recovering the time, the ONU transmits the
time to the base station by means of the 1588v2 or time interface.
This scheme does not require a 1588v2 server on the OLT. Therefore, this scheme is
recommended when the upstream network of the OLT supports 1588v2 hop by hop.

Item Data
1588v2 clock source When the 1588v2 clock packets are injected by using the GICK/SPUF
board or the 1588v2 clock packets of the upstream network are
transparently transmitted:
l GE ports of the GICK board: 0/19/0 and 0/19/1
l 10 GE ports of the SPUF board: 0/2/0 and0/2/1
l Clock source selection mode: priority
l Clock priority: p0 > p1
