Hello friend!
Figure 1 UMPTe panel

The UMPTe provides FE/GE0, XGE1, GPS, USB, CLK, CI, and RST ports. The functions of these interfaces are as follows:
FE/GEO, FE/GE2
FE/GE electrical signal transmission port
The FE/GE electrical port on the UMPTg provides surge protection. When the outdoor cabinet uses Ethernet electrical transmission, the SLPU surge protection box is not required.
XGE1, XGE3
25GE optical signal transmission port with a maximum transmission rate of 25000 Mbit/s
GPS
The GPS or GNSS port on the UMPTg1 is reserved.
The GPS or GNSS port on the UMPTg2/UMPTg3 transmits the RF information received by the antenna to the satellite card.
The GPS or GNSS port on the UMPTg supports surge protection and does not need to be configured with a GPS surge protector.
CLK
Cl
Used for BBU interconnection or USU interconnection.
RST
Reset switch.
I hope it helps you.
