Your system has a Modem Daughter Card (MDC) slot, in which you can install a Modem Daughter Card.
DANGER During electrical storms, do not connect the cable to or disconnect it from the telephone outlet on the wall.
DANGER Electric current from power, telephone, and communication cables is hazardous. To avoid shock hazard, disconnect the cables before opening the cover of this slot.
