if it is, MMU is the Modem Unit, where you connect your IF cable going to the RAU- radio unit that will be connected to the antenna. you will extract or map the E1s from the MMU going out to your cross connect terminal or DDF. SMU-switch multiplexing unit is used if you are going to do a Hot/Standby 1+1 mode.. 2 MMUs..
means 6 transceivers per sector. approximately 6 x 8 = 48 subscribers simultaneously per sector. so the whole site can provide approximately 48 x 3 = subscribers.. i dunno math…

try this on your OMT, create 3 antenna with uncombined TX combining/RX antenna sharing using CDU-G.. then choose 1+1+2 on your SCC.. its really possible.. 1 TX cable from first dTRU to the TX1 of first CDU, then 2nd TX cable of 1st dTRU to TX1 of 2nd CDU, then connect TX cables from the 2nd dTRU at position 5 (start count 1 to 6)to TX1 & TX2 of the 3rd CDU.
