交换局管理员(XM)是爱立信网管系统NMAS操作和维护(O&M)系列产品之一,它能在网元级提供O＆M功能支持,主要用于电话和蜂窝网中AXE网元的管理。由于它还具有TMN Q3接口,因而也可用于非爱立信交换机中的告警、文件和命令的处理。
The Office Manager (XM) is one of the NMAS Operations and Maintenance (O & M) products from Ericsson’s network management system that provides O & M capability support at the NE level for the management of AX NEs in telephony and cellular networks. Because it also has a TMN Q3 interface, it can also be used for the handling of alarms, files and commands in non-Ericsson switches.
