Combination Extensions
A combination extension is an extension with two devices connected to
it—either two standard devices, or a system phone and a standard device (but
not two system phones). (For instructions on how to install a combination
extension, see the PARTNER

The following are examples of useful combination extensions:
System phone plus standard phone, for power failure backup on
extensions 10, 16, 22, 28, 34, 40, 46, and 52
extensions 10, 16, 22, 28, 34, 40, 46, and 52
System phone plus answering machine
System phone plus fax machine
System phone plus headset
System phone plus an external alert (such as a bell or chime).
Using the telephones in a combination extension is fairly simple. The main point
to understand is that the two telephones share a single extension in the same
way several home telephones share a single line. A system phone works like it
always does and a standard phone works like it always does when connected to
the system. Only one phone or device can be used at a time, unless you want
to join the two on a single call (the same way two people can pick up the same
call on different telephones at home). Furthermore:

Both phones share the same extension number.
Both phones share the same voice path; that is, when either phone is
busy, the extension is busy.

Calls ring at both phones.
A second call can ring at the system phone while the standard phone is
busy, but do not use the system phone to answer the second call until the
standard phone is idle or the first call will be disconnected.

If you make a voice-signaled intercom call to a combination extension
with a system phone, only the system phone signals.

Call Waiting (#316) does not work on a standard phone in combination
with a system phone.
with a system phone.
The lights on the system phone show what the standard phone is doing
as well as what the system phone is doing. For an explanation of light
patterns, see “Lights” at the beginning of this chapter.

If Privacy is active at a combination extension, no other extension can
join a call in progress at either a system phone or a standard device.
(However, a phone can interrupt a call on a standard device at the same
extension. For example, if a system phone and modem are combined at
an extension, picking up the handset of the system phone could interrupt
a modem transmission, even if Privacy is active.)
