A modem-controlled display requires the use of an internal or external modem at the
computer and another modem in the display. The local phone company must provide
a dedicated phone line to the display and identify the colors used by the Tip wire and
by the Ring wire. The telephone cable is run to the modem board in the display or is
connected to a junction box with a quick connect plug that connects to the display.
The phone cable must be routed though conduit.
Do not run signal and display
power through the same conduit. Refer to
Figure 27
and Drawing A-174342 for the
system layout.
