Ref:l In UMTS mode, only the UBBP board in slot 2 or 3 can provide CPRI ports.

Can you please confirm if this is correct. I am pretty sure I have seen some working U+L Site with Separate MPT and Slot 5 had the connection to the RRUs through it's CPRI Ports.
If this statement is correct, how come that site had working UMTS Cells ?
