Man-Machine Interface
The Lineside T1 card provides an optional Man-Machine Interface (MMI)
that is primarily used for T1 link performance monitoring and problem
diagnosis. The MMI provides alarm notification, T1 link performance
reporting and fault isolation testing. The interface is accessed through
connections from the I/O panel to a terminal or modem.
The MMI is an optional feature since all T1 configuration settings are
performed through dip switch settings or preconfigured factory default
settings.

I/O panel to a terminal or modem. Multiple cards (up to 64) can be ser ved
through one MMI terminal or modem by cabling the cards together.
The MMI is an optional feature since all T1 configuration settings are
performed through dip switch settings or preconfigured factory default
settings. The man-machine interface is discussed fully in "Functional
