status and alarm management, software version management, 

device test and external alarm collection. 

ii. DBS 

The whole application layer is designed with the database as a core. 
The database coordinates to assign configuration parameters. It 
also synchronizes data between the active and standby CMMs and 

between the foreground and the background. 

iii. LMU 

It is the local O&M unit, including two parts: foreground agent and 
background operation interface. 
It works with the database synchronization module to complete the 
local parameter configuration, equipment status and alarm 

collection. It also includes operating interface of equipment test to 
implement test functions of the local BTS. 
The system tool part is a series of developer-oriented tools for 

system diagnosis and test to rapidly locate faults. 

FUC 

The FUC software module is located in the TPU of the TRM module. It 
processes the radio signaling over every radio carrier and signaling on the 

BSC interface and manages all channels. Its major functions are as follows: 

1.  It processes and converts GSM signaling protocols, including the layer-

2 protocol LAPD with BSC, the layer-2 protocol HDLC with CMM, the 
layer-2 protocol LAPDm with the Um interface and the layer-3 radio 

resources management protocol of GSM. 

2.  It is responsible for the TDMA multi-frame framing on the Um interface, 

frame number (FN) receiving, frequency hopping calculation and 
management & control over CHP. 

3.  It manages OB06 and loads the FUC software and DSP program. It 

supports packet switching services (GPRS or PS for short).
