XM is software that provides operation and maintenance support for network elements (NEs). It is primarily used at the network element level of AX appliances in telephony and cellular mobile communications and also includes the Q3 interface of the Telecommunications Management Network (TMN). That is, XM can also handle alerts, files, and instructions for non-AX type switching devices. XM is one of several operations and maintenance tools in Ericsson’s Network Management System (NMAS). With XM, switching networks across the region can be efficiently managed at OMCs or Network Management Centers (NMCs).
