of the device on one side of the network after the port loopback or hardware loopback is
configured on the E1 port of the device on the other side of the network.
Procedure
Step 1
Configure a local loopback on the E1 port.
If the E1 port of the ONU is used to provide access for the private line services, the configurations
are as follows:
huawei(config)#
interface tdm 0/1
huawei(config-if-tdm-0/1)#
loopback 0 local
This operation will interrupt the service, continue? (y/n)[n]:
y
If the E1 port of the EDTB board is used to provide access for the private line services, the
configurations are as follows:
huawei(config)#
interface edt 0/2
huawei(config-if-edt-0/2)#
loopback 0 local
Step 2
Use the E1 line test instrument to send packets.
NOTE
Ensure the synchronization between clocks. It is recommended that the E1 line test instrument should use the
self-generated clock, the OLT should trace the clock of the E1 line test instrument, and the ONU should trace
the clock of the OLT.
The test duration must be equal to or longer than 12 hours. No alarm information is displayed
on the test instrument, and the bit error rate (BER) must be lower than 1E-9.
----End
Follow-up Procedure
You can collect the packet statistics to check whether the CESoP and TDM connections are
normal.
l
Collect the statistics of packets sent and received by the CESoP connection on the ONU.
huawei(config)#
display cesop-connect statistics 0
------------------------------------------------------
CONNECTID : 0
------------------------------------------------------
Lost Packet Count: 0
Received Packet Count: 58733
Transmitted Packet Count: 58732
Overflow Jitter Buffer Times: 0
Underflow Jitter Buffer Times: 0
Received Abnormal Packet Count: 0
Received Sn-error Packet Count: 0
Received Ssrc-error Packet Count: 0
------------------------------------------------------
In the command output, the number of received packets must be the same as that of sent
packets.
l
Collect the statistics of packets sent and received by the TDM connection on the OLT.
huawei(config)#
display tdm-connect statistics 0
---------------------------------------------------------------
Statistics on ONU side:
Discarded Packets : 0
Received Packets : 132252
Transmitted Packets : 132253
