Run the clock source command to configure the line clock of E1/STM-1 port 0/5/0
on the TOPA board as the system clock source. Set the ID of the clock source to 0.
The clock module automatically judges the type of the specified clock source (E1/
STM-1) and selects a reference source for phase lock based on priorities.
huawei(config)#clock source 0 0/5/0
2. Configure a priority for the system clock source.
Run the clock priority command to set the priority of clock source 0 to the highest
priority.
huawei(config)#clock priority system 0
3. Query configurations and the status of the system clock source.
Run the display clock source system command to query configurations and the status
of the clock source. Ensure that configurations of the system clock source are correct
and the status is Normal.
huawei(config)#display clock source system

Run the display clock mode command to query the clock working mode. Ensure that
the clock daughter board works in tracing mode.

l Configure a clock on the ONU.
1. Configure the GPON line clock as the system clock.
The system clock of the OLT is delivered to the ONU through the GPON port on the
OLT, achieving clock synchronization between the OLT and the ONU.
a. Run the clock source command to configure the clock recovered from the GPON
upstream port as the system clock of the ONU.
b. Run the clock priority command to configure the priority of the clock source.
huawei(config)#clock source 0 0/0/1
Clock source set succeeded
huawei(config)#clock priority system 0
2. Configure the system clock as the transmit clock for an E1 port.
a. Run the interface tdm command to enter the E1 port configuration mode.
b. Run the tx clock or port portid udt system command to configure the system
clock as the transmit clock of the port.
c. Run the display port state command to query the transmit clock of the E1 port.
huawei(config)#interface tdm
huawei(config-if-tdm-)#port 0 udt system
