							Glossary
A
Account Code
A group of numbers, up to 16 digits in length, entered by station users during
incoming or outgoing calls; the system uses account codes to identify the calls by
category, or special grouping, for call accounting purposes.
All-Call Paging
Paging through the intercoms of all stations in the system.
Assist Button
A button that you can program that will let you send a message requesting assistance
to the LCD of another telephone.
Attendant

Automatic Route Selection (ARS)
ARS allows the system to automatically select the least costly line group available to
a station to route a call. The system modifies the dialed number, if needed, to match

over, if and how to modify a number, and costing information) based entirely upon
the programming of the system.
Automatic Station Relocation
Process by which the system automatically recognizes particular stations if they are
relocated to a different station port; the same class of service and station features are

							Speakerphone
Characteristics
When using your speakerphone, the microphone and loudspeaker are farther away
from you than when you use a handset. Both the signal from the loudspeaker and the
signal to the microphone must be strengthened.
When microphones and loudspeakers are close together (such as in a speakerphone),
additional amplification typically generates a ringing sound (public address systems
do this if the volume is too high or the microphone is too close to a loudspeaker).
Full-Duplex Speakerphone Characteristics
TheImpact SCS8324F-** speakerphone uses the latest full-duplex speakerphone
technology. (Full-duplex technology enables both parties on a speakerphone call to
speak simultaneously—half-duplex speakerphones allow only one person to speak
at a time.) The8324F-**will operate in either full-duplex or half-duplex mode
depending on the current line conditions.
At the beginning of each call the telephone must perform a “speech training” test. To
achieve optimum performance from the full-duplex speakerphone, Comdial recom-
mends that each user in turn speak about 10 consecutive words to allow the
telephone to “train” itself. Note that during the “speech training” test, the
speakerphone is operating in half-duplex mode.
Depending on the telephone line conditions and the type of speakerphone at the
other end, it may not be possible for the8324F-**to operate in full-duplex mode. If
the speakerphone at the other end is a half-duplex speakerphone and both parties are
in speakerphone mode, the half-duplex speakerphone is the controlling factor,
preventing the8324F-**from operating in full-duplex mode.

							NOTE: Pressing any button (mute, hold, etc.) on the speakerphone while in
full-duplex mode causes the system to perform the “speech training” test
again. For example, if you pressMUTEwhile in full-duplex mode, when you
release the call from mute, the system will perform the entire “speech training”
test again.
Speakerphone User Guidelines

Both parties can not talk at the same time. You must wait for silence out of
your loudspeaker before talking. You must stop talking to hear the other
party.

Background noise may prevent the sound-activated switches from operating
properly. Avoid placing the speakerphone where it will detect sounds from
typewriters, keyboards, printers, paging systems, and other equipment.

Speak slightly louder than normal and with a clear, authoritative voice. For
the microphone to best detect your voice, speak within three feet of it and
face the telephone.

Raising the volume of the loudspeaker makes it easier for the
sound-activated switches in your telephone to select the distant party’s
voice. Lowering the volume of the loudspeaker makes it easier for the
switches to select your voice.

Since the system takes several seconds to provide the best switching, con-
stant sound patterns—such as elongating your words and playing exter-
nally-supplied music—may prevent the sound-activated switches from
operating properly.

Place the telephone on a hard surface and away from table edges. Do not
place the telephone in corners or enclosures. Do not let obstructions come
between you and the microphone. Rooms with hard, flat surfaces that reflect
sound may affect the sound-activated switches.


If you are using a handset and the other party is using a speakerphone, avoid
breathing heavily into your microphone. Avoid other sounds that may affect
the distant telephone’s sound-activated switches.


In some situations, such as when either you or the distant party are in a noisy
environment, you may have to lift your handset to ensure a clear conversa-
tion.


When both you and the distant party use speakerphones, the sound-activated
switches can occasionally detect both voices simultaneously, thus blocking
out both voices.
