name: RCA
full_form: RC Analysis
context: RCA identifies the cause of a number of alarms. AC1 correlation result can provide hints of the cause of alarms (see 5.1.1.1). It is noted that root cause may not be singular in that alarms can be caused by multiple causes. Furthermore, root cause may not be an alarm itself. It can be a configuration change gone wrong (e.g. wrong version of software is loaded into NE, wrong NE attribute values are configured). We question the feasibility of using standardized pre-programmed rules for RCA function. This document recommends: The use of experienced operator, knowledgeable of network configurations, network activities and NE peculiar behaviours, with hints from AC1 function outputs, to identify root cause of alarms. The use of AC1 function (see 7.3.1) to report the root cause of an AC1 Group (see 6.1), in case it identifies the root cause of the AC1 Group.
description: Root Cause Analysis (RCA) is a procedure used to identify the underlying cause of a set of alarms or issues within a telecommunications network. It involves analyzing data and using experienced operators, knowledgeable of network configurations and activities, to determine the root cause of problems.
explanation: The context describes RCA as a systematic process for identifying the origin of network issues, making it a procedure.
