Audio conferencing:
Audio conferencing involves the live exchange of voice messages over a telephone net work.
To make audio conferencing more comfortable speaker phones are available to permit callers physical flexibility.
These work satisfactory for up to eight or ten participants.
More sophisticated speakers are available for larger groups.

Audio teleconferencing options
Dedicated conference networks
Dial-up networks
Meet-me conferencingDirect-dial conferencing system

Mr.vinifred.K. Associate Professor ACONSlide8
Dedicated Conference Networks:
A dedicated conference network permanently wires preselected locations together.
To conference, callers need only to pick up the phone at each location.
These system can be very large.
Example the University of Wisconsin uses a network of more than 200 locations throughout the state to disseminate information and teach classes.
8
Mr.vinifred.K. Associate Professor ACONSlide9
Dial-up Net works:
Dial-up networks use the public switched telephone network.
In the telecom operator assisted mode, the operator calls and connects all participants.
This system works well for a few locations, but difficulties occur when numbers increase.
9
Mr.vinifred.K. Associate Professor ACONSlide10
Meet – Me conferencing
“Meet Me” conferencing, in which each participant calls the conferencing center from any convenient location.
If everyone is prompt, a large number of locations can be interconnected for conferences in five minutes or less.
The sound quality is superior to that of
tele-co conferencing and is generally unaffected by numbers of participants.
10
Mr.vinifred.K. Associate Professor ACONSlide11
Direct Dial Conferencing system:
Direct dial conferencing system is an innovation that makes it possible for one caller to set up a telephone conference with up to six additional participants by using a touch tone phone.

Mr.vinifred.K. Associate Professor ACONSlide12
AUDIOGRAPHIC TELECONFERENCING:
“Audio graphics” refers to the transmission of print and graphic information over telephone lines to complement voice communication with visuals.
It includes a variety of devices; electronic pens, blackboards, and tablets as well as computer systems, slow scan television microfiche,
telewriters
and facsimile machines.
12
Mr.vinifred.K. Associate Professor ACONSlide13
AUDIOGRAPHIC TELECONFERENCING:
Although not widely used, a potentially useful educational device is the electronic blackboard.
The
blackboard converts writing to audible tones which are transmitted over telephone lines, received at one or more locations and displayed upon a television screen.
13
Mr.vinifred.K. Associate Professor ACONSlide14
VIDEO TELECONFERENCING
Video conferencing combines the audio and visual media to provide interactive voice communications and television pictures.
The images include anything that can be captured by a television camera.
A number of options exist, include, freeze-frame television, compressed video systems, and full motion video system.
14
Mr.vinifred.K. Associate Professor ACONSlide15
Freeze – Frame Television
Freeze
– frame, or slow scan television uses the narrowband telephone system to transmit data, voice and still video images.
Transmission
time may vary from a few seconds to more than a minute.
15
Mr.vinifred.K. Associate Professor ACONSlide16
Compressed video system
A
compressed video system also uses a telephone data circuit.
It compresses the video signal to eliminate redundant electronic information with a picture processor or codec.
The video picture appears instantly but there may be some
blurring of fast movements.
16
Mr.vinifred.K. Associate Professor ACONSlide17
Full Motion Video System:
A full motion video system uses wideband channels to send video, voice and data. Because of the large channel capacity, it transmits a full video picture with continuous motion instantly, using cable, microwave or satellites.
17
Mr.vinifred.K. Associate Professor ACONSlide18
Computer conferencing:
Computer
conferencing permits two or more people to communicate with each other via computer terminals in a non-real time mode.
It
is like “electronic mail” because the user can put a message in to the computer and have it retrieved and answered later.But conferencing technology goes further, specific software programs have been developed that permit members of a conference to interact with each other and to access a wide variety of stored information relevant to their objectives.
18
Mr.vinifred.K. Associate Professor ACONSlide19
Computer conferencing:
Computer conferencing adapts to course teaching, student counseling and informed information exchange.
The
university of Michigan is the educational leader in this field.

USES OF TELECONFERENCE
It
can reach large or sparsely populated areas.
It provides broader access to public meetings.
A wider group of participants means a broader range of ideas and point of view.
Teleconferencing saves an agency time and travel costs.
It saves people money.
It saves time.
It is useful when there is an issue in state or region wide.
It helps to increase the number of participants.
It is useful for training.
It is used for networking among transportation professionals on public involvement and other topics.

Mr.vinifred.K. Associate Professor ACONSlide21
DRAWBACKS OF TELECONFERENCE:
Teleconferences are
somewhat formal
events.
A large number of people is difficult to manage in a single conference.Costs can
be
high.
It takes
time to
organize.
Staffing needs
can be
significant.
Community people
are alienated if a meeting is poorly
implemented.
It reduces
opportunities for face-to-face contact
the goals must be clear and
manageable.
21
Mr.vinifred.K. Associate Professor ACONSlide22
ORGINISING TELECONFERENCE:
One person should be
incharge
of selting up a teleconference. The individual makes preparatory cells to each participant, establishes a specific time for the teleconference and makes the cells to assemble the group. The same person should be
incharge of setting an agenda based on issue brought up by individual participants.
Equipment for telephone conference is minimal speaker phones allow several people to use one phone to listen to and speak with others, but they are not required. Individuals can be contacted on their extensions and participate fully in conversations.
22
Mr.vinifred.K. Associate Professor ACONSlide23
PARTICIPANTS FOR TELECONFERENCE:
Any
one can participate:
Teleconferencing
broadens participation with its code geographical coverage.
People
living in remote areas can join in conversations.
Participation
becomes available even for the mobility restricted, those without easy access to transportation, the disadvantaged and elderly.
23
Mr.vinifred.K. Associate Professor ACONSlide24
Participants gather at tow or more locations:
Communicate via
phone or video. The
event requires planning, so that participants are present at the appointed time at their divergent locations.
24
Mr.vinifred.K. Associate Professor ACONSlide25
Participant should know what to expect during the session:
A well-published
agenda in required
.
It is helpful to brief participants so they understand the basic process and maximize the use of time for their participation.
For
(ex) basic concerns like speaking clearly or waiting to
speak
in turn are both elements of a successful teleconference based meeting.
25
Mr.vinifred.K. Associate Professor ACONSlide26
LEADING A TELECONFERENCE
Community
people can lead the conversation:
The
moderator need not be an agency staff person.
If
the teleconference is taking place at the request of community people, it is appropriate that a community people, it is appropriate that a community resident lead the session.
Agency
staff should feel free to ask questions of community people to obtain a complete understanding of their point of view.
26
Mr.vinifred.K. Associate Professor ACONSlide27
Person-in-charge
A
person-in-charge is necessary to prevent the conversation from becoming chaotic.
A
teleconferencing facility coordinator can train agency staff or community people to lead the process.
27
Mr.vinifred.K. Associate Professor ACONSlide28
A trained facilitator, moderator or group
leader
A
moderator needs to orchestrate the orderly flow of conversation by identifying the sequence of speakers.
A staff person can be trained to open and lead the teleconference.
28
Mr.vinifred.K. Associate Professor ACONSlide29
COST FOR TELECONFERENCE
Teleconference
cost vary depending on the application.
For modest teleconferencing efforts, equipment and facilities are the principal costs.
It is possible to share teleconferencing cost among organization.
29
Mr.vinifred.K. Associate Professor ACONSlide30
EFFECTIVE WAYS FOR USING TELECONFERENCE:
Teleconference is
effective when participants have difficulty attending a meeting.
Teleconference is
effective when it focuses on specific action items.Teleconference helps give all participants an equal footing.
