1.2 Using Your Speakerphone

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).

NOTE: The 8324F-** speakerphone can function in the full-duplex or half-duplex mode. Both sets of guidelines (section 1.2.1 and section 1.2.2) are applicable to the 8324F-**.

The 8012S-**, 8024S-**, 8324S-**, and 8312S-** speakerphones only function in the half-duplex mode—only section 1.2.2, Speakerphone User Guidelines, apply to these telephones.

1–2 LCD Speakerphone Reference Manual

GCA70–245

Introducing The LCD Speakerphone

1.2.1Using A Full-Duplex Speakerphone

The Impact SCS 8324F-** 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.) The 8324F-** will operate in either full-duplex or half-duplex mode depending on the current line conditions. For example, satellite calls or calls with a delay involved may prevent the telephone from operating in full-duplex mode.

At the beginning of each call the telephone must perform a “speech training” test. To achieve optimum performance from the full-duplex speakerphone, Comdial recommends 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 the 8324F-** 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 the 8324F-** from operating in full-duplex mode.

When using a full-duplex telephone, you must be aware of these different situations and react accordingly when the far-end party does not respond. However, you will discover it is much easier to interrupt the far-end talker and have a more natural conversation than you can have with a half-duplex speakerphone.

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 press MUTE while in full-duplex mode, when you release the call from mute, the system will perform the entire “speech training” test again.

GCA70–245

1.2.2Speakerphone User Guidelines

NOTE: The speakerphone user guidelines in this section that do not apply to the Impact SCS model 8324F-** when it is operating in full-duplex mode are so noted. However, when the 8324F-** is in half-duplex mode or in “speech training” mode, all of the following guidelines are applicable.

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. Does not apply to model 8324F-** when in full duplex mode.

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, constant sound patterns—such as elongating your words and playing externally-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 conversation.

1–4 LCD Speakerphone Reference Manual

GCA70–245

Introducing The LCD Speakerphone

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

To manually place a call using your speakerphone,

1.Press the INTERCOM or line button.

2.Dial the number.

3.When party answers, speak toward the telephone.

To automatically dial a number using your speakerphone,

1.Press the preprogrammed speed dial or DSS button and speak toward the telephone when your party answers.

To answer a call with your speakerphone,

1.Press the INTERCOM or line button with flashing red or orange light.

2.Speak toward the telephone to answer the call.

3.To end a call with your speakerphone, press SPEAKER.

2.2 Creating The LCD Response Messages

When you are busy or are away from your desk, you can set a message at your telephone that will be received by any LCD speakerphone within your system. Your system provides two default messages: “Back at . . .” and “Call . . .” In addition, you can add eight customized messages, or you can create up to ten messages if you choose not to use the two default messages.

NOTE: If you intend to create a response message to a voice announce, remember that this is also a message, and that it uses one of your message locations.

To store the LCD messages,

1.Write your messages on the chart on page 2-5 (each message can have up to 16 characters).

2.Use the letter code table (on page 2-4) to assign a number to each letter.

3.Write these numbers on the chart line beside the message letters.

4.Press INTERCOM.

5.Dial # 0 5.

6.Dial a message location number (1-0).

7.Dial # to clear current message.

8.Compose your messages by dialing the two-digit codes that relate to the letters. See the code table on page 2-4.

2.3 Direct Inward Station Dialing

The direct inward station dialing (DISD) feature allows an external party to call an intercom station directly without assistance from the attendant (over a line programmed for DISD). As the system attendant, you may instruct callers to make DISD calls when necessary.

You may give the caller a DISD line number and the extension number associated with the station he or she is trying to reach. Future calls from the caller to a specific party will not have to be serviced at the attendant’s station, although a ring-no answer or busy condition at the called party’s station will result in the system’s handling the call in another manner (described below).

When a caller makes a DISD call from an outside line, he or she will initially hear ringing. The system will answer the call with a DISD continuous dial tone; the caller can then dial an extension number.

If called station is idle, a tone is sounded and called station rings.

If the call is answered by another station user, the caller can ask for transfer to desired station.

If ringing stops and dial tone sounds again, the caller can dial another extension number.

If called station has call forward feature set, forward station rings.

If called station is busy, call is placed on hold and camped-on at busy station. If camp-on is not answered within a transfer recall timeout period, busy tone is given, followed by a DISD dial tone.

2–6 LCD Speakerphone Reference Manual

GCA70–245

Programming The Attendant Features

NOTE: The system will return the caller to DISD dial tone two additional times and then drop the line.

If called station is busy but is part of a hunt group, DISD call is routed to idle station in hunt group, if available; otherwise, the call is camped-on at dialed station. Hunt group is followed when caller hears ringing but receives no answer.

If an invalid extension number is dialed, an error tone is sounded before DISD dial tone is returned (caller can redial). If mistake in dialing is made, caller can dial for new DISD dial tone.

If extension number dialing is not completed within the programmed dial time limit, call is routed to DISD assist station if available; otherwise, the line is dropped.

NOTE: See section 2.14 for DVA programming used with the DISD feature.

2.4 Naming The System Telephones

If you have an LCD speakerphone, this feature lets you know who is calling you. You can assign either a personal name or a group name to each system telephone. This name can contain up to seven letters and will show up in the user’s display and/or in the called party’s display. Typical names could be SRVC, MKTG 1, K SMITH.

Name the system telephones as follows:

1.Use letter code table (page 2-9) to compose names for all telephones requiring them (the system accepts up to seven letters per name),

2.Press INTERCOM,

3.Dial # 0 6,

4.Dial the station number of the telephone to be named (10-57),

5.Dial # to clear current entry,

6.Dial two-digit codes that correspond to letters in name,

7.Dial to continue entering station names (repeat above steps beginning with station selection 10-57),

8.Press SPEAKER to end,

2.11 System Alarm Reporting

Occasionally, the DSU system will fail to communicate with a particular station; it could be that the station has been disconnected from its station port or that the system printer is off line. When the system experiences these disruptions, an alarm signal will display at the attendant’s station or any LCD speakerphone when enabled by class of service programming. In order to review the system alarms, the attendant can command the system to present alarm codes on the station display.

When this feature is provided, a flashing appears on the first line of your telephone’s LCD to indicate that new alarms are present. It is a good idea to write down which alarms are displayed so that you may report the nature of the alarms to your system installer.

To display alarm codes,

1.Press and hold for 5 seconds. The following status reports will be displayed:

Station disconnected from station port for more than five minutes. Month, day, station port number, and station extension number are shown.

Display shows: “Mo/Da Pxx xxxx A”

Communications difficulty between a station and the common equipment. The number of parity errors, up to 256, and the affected station port are shown.

Display shows: “ xxx PARITY Pxx ”

Data printer off-line.

Display shows: “PRINTER OFF LINE”

You may press 0 to cancel the alarm report displays.

After the information has been shown on the display, the disappears until another alarm occurs.

Programming The Attendant Features

2.12 Transferring Calls To The Voice Mail System

As the attendant, you will not always have time to hand-write messages for all of the people in your group. Transferring some calls to a voice mail system provides an easy, efficient way for callers to record lengthy messages to be retrieved by individual station users later.

You can program your attendant’s telephone so that you will be able to transfer calls to voice mail by pressing a single button (known as the

Transfer To Voice Mail autodial button).

To program a Transfer To Voice Mail autodial button at your telephone,

1.Press INTERCOM.

2.Dial 1.

3.Press programmable button for Transfer To Voice Mail autodial button location.

4.Dial 6.

5.Dial extension number plus “2" of the voice mail station port.

6.Press SPEAKER to end. (Label button location.)

To transfer calls to the voice mail system,

1.While on a call, press preprogrammed Transfer To Voice Mail autodial button.

2.Dial extension number followed by “2" of party to receive voice mail message. The system will automatically dial into voice mail and direct the message to the appropriate voice mail location for later retrieval.

2.13Transferring Recalls To A Secondary Attendant Telephone

The system installer can arrange for another telephone (station 12) to serve as a secondary attendant location. When this feature is enabled through programming, incoming calls ring at the regular (or prime) attendant’s station, but recalls from unanswered transfers or timed hold recalls will ring at both attendant stations simultaneously. Neither the prime attendant nor the alternate attendant can program the feature directly; only the installer, through class of service programming, can enable or disable the alternate attendant.
