OSS and Network Management Flashcards

What does Ericsson's OSS (Operations Support System) primarily enable operators to do?

Answer: Monitor, configure, and manage network elements across the RAN and core

Ericsson's OSS provides centralized tools for network monitoring, fault management, configuration management, and performance management across the operator's infrastructure.

What is the primary role of Ericsson's Network Manager (ENM)?

Answer: To centralize FCAPS network management for Ericsson network elements

Ericsson Network Manager (ENM) provides Fault, Configuration, Accounting, Performance, and Security (FCAPS) management for Ericsson RAN, transport, and core nodes.

In ENM, what does the 'CM' (Configuration Management) function allow operators to do?

Answer: Read and modify network element configurations programmatically

Configuration Management in ENM allows operators to read, modify, and audit the parameters of network elements (NEs) from a central interface.

Which Ericsson OSS component is responsible for collecting and presenting network performance KPIs?

Answer: PM (Performance Management) service in ENM

The Performance Management service in ENM collects performance counters and KPIs from network elements and presents them in reports and dashboards.

What is the purpose of Ericsson's Alarm Management in ENM?

Answer: To receive, correlate, and display faults from network elements in real time

Alarm Management collects alarms from NEs, correlates related events to reduce noise, and presents active faults to operators for timely resolution.

In Ericsson's model-driven OSS approach, what is a Network Resource Model (NRM)?

Answer: A formal data model that describes the managed objects and attributes of a network element type

An NRM defines the managed object classes, attributes, and relationships for a specific NE type, enabling standardized CRUD operations from the OSS.
