for data transmission on both the GSM and UMTS sides when a GSM+UMTS base station works
in separate transmission mode.

Transmission Cable Connections in the GSM+LTE Base Station in Co-
Transmission Mode
A GSM+LTE base station implements IP over E1 and IP over FE/GE co-transmission based on
the interconnection between the FE ports (optical or electrical type) on the GTMU and LMPT
panels. Based on the co-transmission, route backup can be implemented. 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.
IP Over E1 Common Transmission
shows the transmission cable connections for a GSM+LTE base station when the
E1/T1 port on the LTE UTRP is connected to the transmission equipment and the FE/GE optical
port on the LMPT is interconnected to the FE/GE optical port on the GTMU.
