1.1 Purpose and Scope

This document defines the procedures to activate the Policy and Charging Application (PCA) feature on a DSR Network Element (NE). These procedures can be performed either:
  1. as part of a new DSR installation, after the standard DSR installation is complete, but before the NE is in-service, or
  2. on an in-service DSR NE, where the PCA feature is activated during a planned maintenance window to minimize the impact to network traffic.

This document also provides a procedure to deactivate PCA after it has been activated. For deactivation procedures, see Feature Deactivation Overview.

PCA configuration following activation is beyond the scope of this document. For information about PCA configuration postactivation, see PCA User Guide.

No additional software installation is required before performing this procedure. The standard DSR installation procedure has loaded all the required software even if the PCA feature is activated later.
