b. Variations in filtering, amplifiers, and optical loss may cause the actual system gain to vary

+/- 6 dB. All paths can be normalized by adjusting uplink attenuation settings in the BIU.

3. This procedure should be repeated for each frequency band in the system

Note: Uplink Pilot Frequency Switch should be off during normal operations. This function is intended for testing, verifying,

and adjusting uplink performance and will interfere with normal operation of the system.

5.5 Monitoring and Alarms

5.5.1 Operational Status

5.5.1.1 Host Unit

The EMS Local GUI graphical interface will notify users of an error or malfunction in the Host Unit with a red

popup “alarm indicator”. The alarms will also be displayed in the lower section of the component window.
