1 INTRODUCTION
This section outlines the concepts and performance objectives involved in the gain
management and fault detection (continuity) of the Digivance CXD system. This section
breaks these topics down into the following areas:
Forward gain management
Reverse Automatic Gain Control
Forward delay management
Reverse delay management
Forward continuity
Reverse continuity.
PA Overpower Protection
Hub Overpower Protection
2 FORWARD GAIN MANAGEMENT
The Digivance CXD system has a compensation feature in the forward path to account for
changes in gain as a function of temperature.. This feature applies on a per RAN basis and is
enabled by default. The operator can disable this feature if desired.
