Confidential and Proprietary Information of ZTE CORPORATION
In the uplink direction, the antenna feeder processor receives RF signals
from MS, and sends them to the RF unit to convert them into digital
signals. Then, the signals are sent to the base band processor for rate
signals. Then, the signals are sent to the base band processor for rate
conversion, decryption and de-interleaving. Finally, after being converted
to the code pattern suitable for long-distance transmission, the signals are
sent to BSC through the Abis interface.

The main functions of each module are as follows:
1. CMM
CMM implements Abis interface processing, BTS operation &
maintenance, clock synchronization and generation, internal/external
maintenance, clock synchronization and generation, internal/external
alarm collection and processing and other functions.
2. TRM
TRM controls and processes the radio channels; transmits and receives
the radio channel data; modulates and demodulates the baseband
signals on the radio carrier; and transmits and receives radio carriers
signals on the radio carrier; and transmits and receives radio carriers
in the GSM system.
The TRM is divided into three units by function:
i. Transceiver Processing Unit (TPU)
