huawei(config)#clock priority system 0
2. Configure the system clock as the Tx clock of the 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 Tx clock of
the port as the system clock.
c. Run the display port state command to query the Tx clock of the E1 port.
huawei(config)#interface tdm 0/1
huawei(config-if-tdm-0/1)#port 0 udt system
huawei(config-if-tdm-0/1)#display port state 0

3. Query the configuration and status of the system clock source.
Run the display clock source command to query the configuration and status of the system
clock source.
huawei(config-if-tdm-0/1)#quit
huawei(config)#display clock source

Result
After the configuration of base station access service is complete, use the test meter to perform
tests on the E1 port of the ONU and the upstream E1/STM-1 port of the TOPA board. The long-
term bit error ratio (BER) and delay should be able to meet the application requirements.
14.3.4 Configuring Ethernet Clock Synchronization
When OLTs access a base transceiver station (BTS) that requires only frequency
synchronization, such as GSM/WCDMA/FDD LTE and when the OLTs are connected upstream
to the packet switched network (PSN) by using the GE/10GE port, the clock can be recovered
from the bit streams on the Ethernet link, implementing synchronization between over the entire
network.
