When you connect a tip/ring device (such as a single-line telephone or an answering machine) and
another piece of equipment (either another tip/ring device or a system telephone) on one
extension, the extension is called a combination extension. (If you combine a single-line telephone
and a system telephone on one extension, you may want to turn off the single-line telephone’s
ringer during normal use.)
You cannot install two system telephones on the same extension, and the combined REN (Ringer
Equivalence Number) of two devices on one extension cannot exceed 2.0. (The REN for a system
telephone is 0.0.)
PARTNER telephones have a built-in auxiliary jack so you can connect a tip/ring device directly to
the telephone without using a bridging adapter; this is called a direct connection. If your telephone
does not have a built-in auxiliary jack, or if you want to connect two tip/ring devices together, you
must use a 267F2 Bridging Adapter.

You can connect a tip/ring device directly to a system telephone by plugging the cord from the tip/
ring device into the AUX jack on the bottom of the system telephone (see
Figure 9-1 ).
