Guys I shared with you the problem and solution about the "Displayed Indicating InsufficientBandwidth When I Attempt to Add an ONU" in iManagerU2000. Sometimes my customers asked me about this.

[Knowledge base - U2000 Access Network] - Displayed Indicating InsufficientBandwidth When I Attempt to Add an ONU-2648539-1

very good !

when add ONT notice bandwidth is not enough ,check how much this pon port bandwidth left first :

Huawei(config-if-gpon-0/5)#display port info 6
-----------------------------------------------------------
F/S/P 0/5/6
Min distance(km) 0
Max distance(km) 20
Left guaranteed bandwidth(kbps) 512
Number of T-CONTs 132
Autofind Enable
FEC check Disable
Admin State On
ONT encryption key switching interval(m) Disable
PON-ID switch Disable
PON-ID identifier 6
-----------------------------------------------------------


1. if left bandwidth verify less , calculate each all the ONT upstream bandwidth occupation :

find all the ONT of this port bind line-profile occupation , the fixed and assured type of DBA should be consider .

for example , if there the line-profile DBA fixed type occupy 5M ,assured type occupy 10M , if ONT bind this profile , this ONT will cost 5M(ONT OMCI management )+5M fixed +10Massured =20M , if GPON port added 60 ONT , it will cost 20M*60 =1200M ,it almost reach to the maximum of bandwidth(GPON upstream 1.25G) ability can be assign .


2. check if opened bandwidth compensate , if opened this feature it will cost double bandwidth .
dba-profile add profile-id 11 profile-name "15M-FTTH" type1 fix 15296 bandwidth_compensate yes

3. if configure ONT from U2000 , after change the line-profile or delete some useless ONT ,please sync OLT data then do other configuration .
