How to Adding an ONU to an OLT Huawei.

In this text, Hong Telecom will tell you how to add an ONU device to an OLT in the FTTX scenario.

Generally, services can be configured for an ONU only after the ONU is successfully added to an OLT.

Data Plan:

Procedure
Step 1 Configure GPON ONU profiles.
GPON ONU profiles include the DBA profile, line profile, service profile, and alarm profile.
DBA profile: A DBA profile describes GPON traffic parameters. A T-CONT is bound to
01, DBA profile for dynamic bandwidth allocation, improving upstream bandwidth
utilization.
02, Line profile: A line profile describes the binding between the T-CONT and the DBA profile, the QoS mode of the traffic stream, and the mapping between the GEM port and the ONU-side service.
03,Service profile: A service profile provides the service configuration channel for the ONU that is managed by using optical network terminal management and control interface (OMCI).
04,Alarm profile: An alarm profile contains a series of alarm thresholds to measure and monitor the performance of activated ONU lines. When a statistical value reaches the threshold, the host is notified and an alarm is reported to the log host and the NMS.

1. Configure a DBA profile.
Run the display dba-profile command to query existing DBA profiles in the system. If
the existing DBA profiles in the system do not meet the requirements, run the dba-
profile add command to add a DBA profile.
Create the same DBA profile for different types of services. Set the profile name to
ftto_dba, profile type to type3, assured bandwidth to 8 Mbit/s, and maximum bandwidth to 50 Mbit/s.

huawei(config)#dba-profile add profile-name ftto_dba type3 assure 8192 max
51200

2. Configure an ONU line profile.
Create a GPON ONU line profile, named ftto_line, and bind it to the DBA profile
ftto_dba.
huawei(config)#ont-lineprofile gpon profile-name ftto_line
huawei(config-gpon-lineprofile-1)#tcont 4 dba-profile-name ftto_dba

Create different GEM ports according to different service types, in which
– GEM port 11 is used to carry management services.
– GEM port 12 is used to carry voice services.
– GEM port 13 is used to carry video services.
– GEM port 14 is used to carry Internet access services.

huawei(config-gpon-lineprofile-1)#gem add 11 eth tcont 4
huawei(config-gpon-lineprofile-1)#gem add 12 eth tcont 4
huawei(config-gpon-lineprofile-1)#gem add 13 eth tcont 4
huawei(config-gpon-lineprofile-1)#gem add 14 eth tcont 4

After the configurations are complete, run the commit command to apply the parameters
settings.
huawei(config-gpon-lineprofile-1)#commit
huawei(config-gpon-lineprofile-1)#quit

3. Configure an ONU service profile.
Create a GPON ONU service profile, named ftto_ser. Configure the capability set of the ETH port and POTS port to adaptive. Then the system automatically adapts to the ONU according to the actual capability of the online ONU.

huawei(config)#ont-srvprofile gpon profile-name ftto_ser
huawei(config-gpon-srvprofile-1)#ont-port eth adaptive pots adaptive

After the configurations are complete, run the commit command to apply the parameters
setting.
huawei(config-gpon-srvprofile-1)#commit
huawei(config-gpon-srvprofile-1)#quit

4. (Optional) Add an alarm profile.
– The default GPON alarm profile 1 is used. The alarm thresholds of the default
alarm profile are 0, which indicates that no alarm is generated.
– In this example, the default alarm profile is used, and therefore the configuration of
the alarm profile is not required.
– Run the gpon alarm-profile add command to configure a GPON alarm profile,
which is used for monitoring the performance of an activated ONU line.

Step 2 Add an ONU.
Connect two ONUs to GPON port 0/1/0. Set the ONU IDs to 1 and 2, SNs to
3230313126595540 and 6877687714852901, passwords to 0100000001 and 0100000002, discovery mode for password authentication to once-on, and management mode to OMCI. Bind the two ONUs to ONU line profile ftto_line and ONU service profile ftto_ser.
There are two methods of adding an ONU: add an ONU offline and confirm an automatically discovered ONU.

A, Add ONUs offline.
If the password of an ONU is known, run the ont add command to add an ONU offline.
huawei(config)#interface gpon 0/1
huawei(config-if-gpon-0/1)#ont add 0 1 password-auth 0100000001 once-on no-
aging omci ont-lineprofile-name
ftto_line ont-srvprofile-name ftto_ser
huawei(config-if-gpon-0/1)#ont add 0 2 password-auth 0100000002 once-on no-
aging omci ont-lineprofile-name
ftto_line ont-srvprofile-name ftto_ser

B, Confirm automatically discovered ONUs
If the password or SN of an ONU is unknown, run the port portid ont-auto-find
command in GPON mode to enable the ONU auto-discovery function of the GPON port.
Then, run the ont confirm command to confirm the ONU.
huawei(config)#interface gpon 0/1
huawei(config-if-gpon-0/1)#port 0 ont-auto-find enable
huawei(config-if-gpon-0/1)#display ont autofind 0
//After this command is executed, the information about all ONUs connected
to the GPON port through optical splitters is displayed.
huawei(config-if-gpon-0/1)#ont confirm 0 ontid 1 sn-auth 3230313126595540
omci ont-lineprofile-name
ftto_line ont-srvprofile-name ftto_ser
huawei(config-if-gpon-0/1)#ont confirm 0 ontid 2 sn-auth 6877687714852901
omci ont-lineprofile-name
ftto_line ont-srvprofile-name ftto_ser
C, (Optional) Bind the alarm profile to the ONU.
The default profile 1 is used in this example.
huawei(config-if-gpon-0/1)#ont alarm-profile 0 1 profile-id 1
huawei(config-if-gpon-0/1)#ont alarm-profile 0 2 profile-id 1

Step 3 Check ONU status.
After an ONU is added, run the display ont info command to query the current status of the ONU. Ensure that Config flag of the ONU is active, Run State is online, Config state is normal, and Match state is match.

When Config state is failed, Run state is offline, or Match state is mismatch:
l If Control flag is deactive, run the ont active command in GPON mode to activate the
ONU.
01, If Run state is offline, a physical line may be broken or the optical module may be
damaged. Check the line and the optical module.
02, If Config state is failed, the configured ONU capability exceeds the actual ONU
capability. In this case, run the display ont failed-configuration command in the
diagnose mode to check the failed configuration item and the failure cause. Then, rectify the fault accordingly.
03 If the ONU does not match, that is, Match state is mismatch, the port types and number of ports undermatch the actual port types and number of ports supported by the ONU. In this case, run the display ont capability command to query the actual capability of the ONU, and then select one of the following modes to modify the ONU configuration:
– Create a proper ONU profile according to the actual capability of the ONU, and
then run the ont modify command to modify the configuration data of the ONU.
– Modify the ONU profile according to the actual capability of the ONU and save the
modification. Then, the ONU automatically recovers the configuration successfully.
