Using a Combination Extension
A combination extension is a PARTNER telephone and a standard telephone (or
other standard device) that share a single extension. For complete instructions
on how to install a combination extension, see p. 2-13.
The following are examples of useful combination extensions:
■
■
■
PARTNER phone plus standard telephone, for power failure backup (exten-
sions 10 and 16).
PARTNER phone plus answering machine
PARTNER phone plus fax machine
Using the telephones in a combination extension is fairly simple. The main thing
to understand is that the two telephones share a single PARTNER extension in
the same way several home telephones share a single number. For example:
■
■
■
■
Both phones share the same extension number.
Both phones share the same "voicepath;" that is , when either phone is busy,
the extension is busy.
The lights on the PARTNER phone show what the standard telephone is
doing as well as what the PARTNER phone is doing. For a description of
light patterns on PARTNER phones, see p. 4-2.
An incoming call rings at both phones.
In the combination extension, a PARTNER telephone works like it always does
and a standard telephone works like it always does when connected to the
PARTNER system. Only one phone can be used at a time, unless you want to
join the two on a single call, the same way you can—on your home phone—
have two people on the same call on different telephones.
There are, however, the following differences from normal operation:

You can handle a call on the standard telephone by pressing buttons on the
PARTNER telephone. For example, you can use the PARTNER phone to
select a specific outside line, and conduct the call on the standard phone.
Or, if someone is on a call using the standard telephone, someone else can
put that call on hold by pressing [
Hold
] on the PARTNER phone. To do this, it
is not necessary to lift the handset of the PARTNER phone.
You can also activate calling features from the PARTNER telephone while the
standard phone is on a call. Simply press [
Feature
] plus the 2-digit dial code.
A voice-signaled call will not signal at a standard phone.
Held calls cannot be retrieved from a standard phone in a combination
extension.
Held calls at a standard phone will not ring back in a combination extension.
Dialing restrictions cannot be guaranteed on a standard phone. (See foot-
note on p. 3-2.)
