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.)
