What does 1+1 radio protection mean?

what does 1+1 radio protection mean?

It’s I presume related to microwave transmission where the ODU is protected through 1 redundant link while there’s already an existing working link

Dear it is related to traffic node. MMU 2B/C/D:1+1 radio protection

Traffic node of Ericsson MiniLink which is a MW unit. It’s related to the port protection of the IDU where E1s are protected through redundancy in case of port fluctuation or SES. 1+1 means there’s only one redundancy.


Thanks a bunch
