l Configure the ONU-side clock (the ONU provides the base station with a clock by
using the clock interface on the panel to implement time synchronization).
This configuration is applicable to time synchronization in the base station where
synchronous base station technologies (TDS-CDMA/CDMA2000/LTE is a representative)
are adopted. If a base station provides the ETH port but does not support 1588v2 packets,
the ONU outputs 1PPS+ToD time for the base station synchronization.
1. Add a system clock source (frequency synchronization).
The 1588v2 clock is issued to the ONU through the optical path of the PON port,
implementing the clock synchronization between the OLT and the ONU.
a. Run the clock source command to add the 1588v2 clock source as the system
clock source.
huawei(config)#clock source 0 0/0/1
b. Run the clock priority command to configure the priority of the 1588v2 clock
source.
huawei(config)#clock priority system 0
2. Configure the 1588v2 time source (time synchronization).
a. Run the ptp enable command to enable the 1588v2 function.
huawei(config)#ptp enable
b. Run the ptp source command to add the 1588v2 clock source as the system clock
source.
huawei(config)#ptp source 0 0/0/1
c. Run the ptp priority command to configure the priority of the 1588v2 clock
source.
huawei(config)#ptp priority 0
3. Configure the time output mode of the clock output interface.
The ONU provides an independent output clock through time output port 0 on the
panel. Configure the clock output signal to 2 MHz and time signal to 1pps+ubx.
NOTE
Configure the clock/time output mode according to actual conditions.
