==Fault management==
A fault is an event that has a lot of significance. The goal of [[fault management]] is to recognize, isolate, correct and log faults that occur in the [[Telecommunications network|network]]. Furthermore, it uses trend analysis to predict errors so that the network is always available. This can be established by monitoring different things for abnormal behavior.

When a fault or event occurs, a network component will often send a notification to the network operator using either a proprietary or open [[Protocol (computing)|protocol]] such as [[Simple Network Management Protocol|SNMP]] (such as WhatsUp Gold, HP OpenView or Sun Solstice–formerly Net Manager), to collect information about network devices or at least write a message to its console for a [[console server]] to catch and log/page. In turn, the management station can be configured to make a network administrator aware of problems (by email, paging, or on-screen messages), allowing appropriate action to be taken. This notification is supposed to trigger manual or automatic activities. For example, the gathering of more data to identify the nature and severity of the problem or to bring backup equipment on-line.

Fault logs are one input used to compile statistics to determine the provided service level of individual network elements, as well as sub-networks or the whole network. They are also used to determine apparently fragile network components that require further attention.  Errors primarily occur in the areas of fault management and configuration management.

Network elements produce alarms (also known as "traps" or "indications") that are monitored by a Fault management system. This function is known as alarm surveillance.<ref>{{cite web |title=Recommendation M.3400: TMN Management Functions |url=https://www.itu.int/rec/T-REC-M.3400/en |website=ITU-T |publisher=ITU-T |accessdate=21 Aug 2019}}</ref> Fault management systems include [[HP Network Management Center|HP Network Node Manager i]],<ref>{{cite web|url=http://hpe.com/software/nnmi|title=Network Node Manager i|website=HPE.com}}</ref> [[Tivoli Software|IBM Tivoli]],<ref>{{cite web|url=http://www-01.ibm.com/software/tivoli/products/netcool-omnibus/|title=Tivoli Netcool/OMNIbus|website=IBM.com}}</ref> EMC Smarts, CA Spectrum, [[NetIQ]], [[TTI Telecom]] Netrac, [[Objective Systems Integrators]] [[NETeXPERT]], opEvents by Opmantek,<ref>{{cite web|title=opEvents - configuring SNMP traps | url=https://community.opmantek.com/display/opEvents/Configuring+opEvents+to+send+SNMP+Traps|website=community.opmantek.com}}</ref> Centina's vSure, Infosim StableNet,<ref>[https://www.infosim.net/products/] Link to Infosim StableNet website</ref> iReveal,<ref>{{cite web|url=http://www.ireveal.co/|title=iReveal|website=ireveal.co|access-date=2017-08-09|archive-date=2017-08-09|archive-url=https://web.archive.org/web/20170809174707/http://www.ireveal.co/|url-status=dead}}</ref> ERAMON etc. Fault isolation tools like Delphi are also available, which are basically used to isolate the fault in any telecom network. A Fault management system is usually the primary feature of a [[network operations center]].
