4.2.4. Description of PWDB-GWRU [Forward path] The RF and modem signal sent from optic module of MHU is first divided into RF and modem signal at Divider in RU, then the CDMA RF signal is amplified and filtered at the RFBS module and the modem signal is conveyed to CPU of NMS controller through FSK modem. The CDMA RF signal input from the RFBS module is linearly amplified up to high power level on HPA, passed through the Front-End Filter Unit, and finally transmitted through an antenna.

6.8.5. Firmware download Download of firmware is normally required when functional upgrade is needed or when bug or erroneous actions of firmware are fixed. Downloading improper images (executable file of repeater CPU) may cause seriously harmful damages to equipment. Download takes the following steps. ① Convert firmware source file (*.bin) to a downloadable file format. Main menu: Action → Image Compression, toolbar: ② Open a pop-up window showing the status of the target equipment for firmware download.
Download procedure Display selected file information Select file Perform operation Display progress of firmware download 6.9. Additional features 6.9.1. ASD (Auto Shutdown) Function 1. If the power level is above the shut down level for longer than 1 second, turn off HPA. 2. During shut down state, monitor RFCHS output power. If the level is below 5dB from shut down level, turn on HPA automatically. 3. Monitor HPA output power in normal operation, and monitor RFCHS output power during shut down.
6.9.2. ALC (Auto Level Control) Function 1. If the power level reaches the ALC level, prevent to increase more than ALC level by using ATT control. 2. By memorizing the existing ATT value, the ATT value before ALC can be reused even when the power is reduced.
