An S7900E switch at the city TV & broadcasting central office (CO) has 12 OLT ports connected to 
150 type-A ONUs. 

 

The type-A ONU vendor recently released an enhanced software version 110 for type-A ONUs. 
This version solves some software bugs found in the previous version 109 and provides some new 
functions. 

 

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