Electrical specifications 185Man-Machine InterfaceThe Lineside T1 card provides an optional Man-Machine Interface (MMI)that is primarily used for T1 link performance monitoring and problemdiagnosis. The MMI provides alarm notification, T1 link performancereporting and fault isolation testing. The interface is accessed throughconnections from the I/O panel to a terminal or modem.The MMI is an optional feature since all T1 configuration settings areperformed through dip switch settings or preconfigured factory defaultsettings.The Lineside T1 card provides an optional Man-Machine Interface (MMI) thatis primarily used for T1 link performance monitoring and problem diagnosis.The MMI provides alarm notification, T1 link performance reporting and faultisolation testing. The interface is accessed through connections from theI/O panel to a terminal or modem. Multiple cards (up to 64) can be servedthrough one MMI terminal or modem by cabling the cards together.The MMI is an optional feature since all T1 configuration settings areperformed through dip switch settings or preconfigured factory defaultsettings. The man-machine interface is discussed fully in "Functionaldescription" (page 391).The Lineside T1 card provides an optional man-machine interface that isprimarily used for T1 link performance monitoring and problem diagnosis.The MMI provides alarm notification, T1 link performance reporting and faultisolation testing.
