Installing the Hardware
Inside wiring (also called "building wiring") enables you to connect phones and
other equipment to the 206 modules. If the building is already wired, the follow-
ing section tells you whether or not the wiring will work. If the building is not
wired, you can have it professionally wired or wire it yourself, as described on
the next page.
Inside wiring consists of wiring runs—one for each extension. A typical wiring
run starts with a wall jack near the system module(s). Then the wiring itself runs
inside the wall to the extension location where it ends in another wall jack. Since
the wiring is hidden, all you see are the wall jacks at both ends (see figure 2-2).
Near the system module(s) there should be a series of jacks, one for each
extension. Each jack is the start of a separate wiring run and should be Iabeled
with either the extension or wiring run number. The wall jacks placed
throughout the building (the ends of the wiring runs) should also be labeled with
the extension or wiring run number.
The PARTNER system works with many types of existing wiring. It requires at
least 2-pair (4-wire) wiring in a "home run" or star (not Ioop) configuration. If
you don't know whether or not the existing wiring is acceptable, test it as follows
(see figure 2-2):
Plug a 206 module into an electrical outlet not controlled by a switch.
Plug one end of a phone cord into an extension jack on the 206 module.
Plug the other end into a wiring run jack.
Plug a PARTNER phone into the wall jack at the end of that wiring run.
Press [ ] and lift the handset. If you hear a dial tone, the wiring is

acceptable. If you don't hear a dial tone, read the next section.
