LBI-38965

1. INTRODUCTION

This manual contains installation instructions, physical and functional descriptions, specifications, and usage information for the Enhanced Digital Access Communications System (EDACS) Billing Correlation Unit and the Centralized Activity Logger (BCU/CAL). A block diagram of the BCU/CAL is shown below.

The BCU/CAL works as a subsystem attached to an Ericsson GE Integrated Multisite and Console Controller (IMC) and can be set to operate as a BCU, a CAL, or both. Each IMC node must have its own BCU/CAL.

BCU and CAL are two separate capabilities which can run independently of each other on the same machine, yet still utilize resources and utilities common to both.

lAdditional information for BCU/CAL can be found in the following publication:
