Procedure
Step 1
Cofnigure a clock on OLT_A.
1.
Add a system clock source.
Configure the E1/T1 line clock input from port 0/5/0 on the EDTB board as the system
clock 0. Set the priority to
0
(highest priority).
huawei(config)#
clock source 0 0/5/0
huawei(config)#
clock priority system 0
2.
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
------------------------------------------------------------------------------
Index Board Source Clk-type State Priority QL
Selected

0 ---
YES
------------------------------------------------------------------------------
Run the
display clock mode
command to query the clock working mode. Ensure that the
clock daughter board works in tracing mode.
huawei(config)#
display clock mode
Clock manage-mode:Third-mode
Clock subboard work-mode:
Tracing
Step 2
Cofnigure a clock on OLT_B.
Obtain the system clock through the GICK board in synchronous Ethernet mode. The clock is
transmitted to the ONU over the GPON line.
huawei(config)#
clock source 0 0/19/0
huawei(config)#
clock priority system 0
Step 3
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.
