Planning the Cable Run in the Apartment
Customer needs dictate where the outlets are located. Visually inspect every proposed outlet location. Be aware
of potential problems like electrical outlets or HVAC ducting. You may not have the ability to drop cable from an
attic or run up from a crawlspace, so your routing options may be limited. The preferred method would be to follow
telecommunication conduit (if it exists) into the building. If not, consider the options shown below.
From the Outside
In the example floor plan, there are two ways to bring the cable in. The solid line shows running the cable from
the exterior, entering the wall and running to the two locations. A suggested routing would be to bring the outdoor
cable in at the ceiling line, run the cable along the top of the wall and split it there. Use methods described
on page 9.4 to position the entry point correctly. You can run non-rated cables a maximum of 50 feet (15 meters)
into an MDU; any further distance requires a CATV-rated cable. A CATV-rated cable is then either fished through
or attached to the wall and concealed with wiremold to reach the outlet location. See Section 9 for specifics. The
cable then continues along the top of the wall, over the door and through the interior wall to the second outlet,
where it is either fished or attached to the wall and
hidden with wiremold.
From the Inside
The dotted line shows a possible route from an interior
hallway. Cable from a riser is run along the top
of the hall wall and enters the apartment at the ceiling.
Use methods described in section 9 to position
the entry point correctly. The cable is split and either
fished through the wall or attached to the outside of
the wall. The cable continues along the top of the
wall, over the door and around to the second outlet,
where it is fished or run down to the outlet location.
