Lucent Technologies PARTNER Advanced Communications System Release 1.0 Installation Manual page 11

extension with two devices connected to it is called a combination extension .
(If you combine a standard phone and a system phone on one extension, you
may want to turn off the standard phone's ringer during normal use.)
You cannot install two system phones 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 phone is 0.0.)
NOTE:
The Call Assistant Intercom Autodialer is not regarded as a standard device.
This means you can connect a standard device to a system phone that also has
an Intercom Autodialer installed.
PARTNER-model system phones have a built-in auxiliary jack so you can
connect a standard device directly to the phone without using a bridging
adapter—see "Using A Direct Connection," below. If your system phone does
not have a built-in auxiliary jack or if you want to connect two standard devices
together, you must use a Lucent Technologies 267F2 Bridging Adapter— see
"Using a Bridging Adapter," below.
Using A Direct Connection
Figure 2 shows how to connect a standard device directly to a system phone,
using the phone's built-in auxiliary jack. (Figure 2 is for illustration purposes
only; the placement of the jacks on your phone may differ.)
