District C branch office (connected to OLT 3/0/1) has20 type-A ONUs under it. The network administrator believes version 109 can meet the currentrequirements and has worked normally. Thus, the network administrator asks to use version 110on a trial basis in the branch office building (ONU 3/0/1:1 is bound with type-A ONUs for FTTBaccess to the building) and use version 109 for other ONUs.
