Lines coming into the building from the telephone company are connected to the input jacks on the monitoring unit. If
these lines do not terminate in modular connectors, solid wire to modular adapters need to be installed. The output lines
from the unit go to the desktop phones. If a telephone switch is present, they connect through the switch first.
