Figure C.1 - EDACS Billing Fault Tolerant Architecture

Redundant MIM processors are added to each RF System interface within the IMC. A duplicate CAM is added, which connects to the redundant BCU/CAL and tape drive.

REDUNDANT OPERATION

The primary and redundant MIM processors operate in a hot standby configuration, i.e., once primary unit failure is detected, the backup becomes the active processor with minimal disruption to calls in progress. The redundant CAM, BCU/CAL and tape drive are operated as on-line mirror duplicates. This eliminates any changeover operation; in the event of failure of one BCU/CAL, or its associated components; the remaining unit continues to operate and process call activity.
