Transmission Cable Connections for a GSM+UMTS Base Station in Common
Transmission Mode
When a GSM+UMTS base station works in co-transmission mode, TDM co-transmission or IP
co-transmission can be used. Based on the IP co-transmission, the GSM+UMTS base station
can implement route backup. That is, four FE ports on the GTMU and LMPT panels are used.
Of the four FE ports, two FE ports of one type are used for interconnection, and the FE ports of
the other type are connected to the transport network.

connect to the BSC and RNC. The GTMU communicates with the WMPT using the backplane
to implement TDM common transmission.
