1.4 Smart-ALC Function
The Repeater’s power amplifier includes power-monitoring circuits with Automatic Level
Control (ALC) that prevents excessive output power while maintaining the power
amplifier linearity
The Smart Automatic Level Control (Smart-ALC) is an innovative algorithm for
automatic Repeater gain adjustment. Combined with advanced control algorithms, S-
ALC is capable of learning the traffic load characteristics and adjusting the Repeater RF
Gain to the desired value. Smart-ALC effectively reduces isolation problems.
NOTE: To reset the Repeater to its highest set gain value, disconnect the Repeater power cable for
several seconds and re-connect.
1.5 Interfaces
All the Repeater interfaces are located on the units’ underside panel. The following
figure shows the interfaces on the D-MBR.
NOTE: The NFPA unit is colored RED.
