A Network Operations Center or '''NOC''' (pronounced "''nock''") is one or more locations from which control is exercised over a Computer or Telecommunications Network , or part thereof. Large organizations may operate more than one NOC, either to manage different networks, or to provide geographic Redundancy in the event of one site being unavailable or offline. The acronym NOC may be prefixed or appended to the network or product managed by that center. An example of this usage is "INOC" being "'''I'''nternational '''N'''etwork '''O'''perations '''C'''enter". It may also be modified in certain letters e.g. "'''NMC'''" being " '''N'''etwork '''M'''anagement '''C'''enter" or "'''SMC'''" being " '''S'''ervice '''M'''anagement '''C'''enter". The network operations center is responsable for monitoring the network for alarms or certain conditions which may require special attention to avoid impact on the networks performance. For example, in a Telecommunications environment the NOC is responsable for monitoring for Power failures, communication line alarms such as Bit Errors , Framing Errors , Out of service (OOS) and other performance issues that will affect the network. The problems should be analyzed before they occur, so the appropriate personnel can correct it in a reasonable time before it becomes a greater issue. In some cases it is almost impossible to anticipate severe conditions like a power failure or Optical Fiber Cable cut, but the NOC would have a procedure in place to call out professionals immediately to remedy the problem. The Noc also escalates issues in a hierarchal format, so for example if an issue is not resolved in a specific time frame a next level is informed to help speed up the process to remedy the issue. NOC]] This term is normally used when referring to telecommunications providers, although a growing number of other organizations such as public utilities ( SCADA ) and private companies have also adopted these centers to both manage their internal networks and to provide monitoring services. The location housing the NOC may also contain many or all of the primary Servers and other Equipment essential to running the network, although it is not uncommon for a single NOC to monitor and control a number of geographically dispersed sites.
