UMPTb2/UMPTb1 working in LTE mode is three times the maximum number of UEs in RRC

connected mode.

Function:

The UMPT performs the following functions:

• Manages configuration and devices, monitors performance, and processes signaling.

• Processes signaling and manages resources for other boards in the BBU.

• Provides the USB port, transmission port, maintenance port to provide signal transmission,

perform automatic software upgrade, and support BBU maintenance on the LMT or

U2000
