get accelerated.
The Flow Aware Packet Accelerated ECS is controlled by the FAPA license, and a CLI at active-charging service. The
CLI is visible only if the license is present and is available only on ASR5500 and QvPC platforms. The FAPA path will
be functional, only if TRM/FP is enabled and the CLI is configured.

This feature provides the operator with additional capacity on deployed systems without any HW addition. The
operators could get 30-40% of the system capacity based on their traffic pattern and deployed call models.
