Video Conferencing
|
The Challenge
The need to meet face-to-face in business can now be extended via the availability of
mature video conferencing equipment.
Video conferencing can enhance the customer experience, improve operation efficiency, and create significant saving in travel cost and time. Like the telephone, video conferencing helps remove the barriers of physical location. Video conferencing enables face-to-face access in real-time, rather than incurring the time to travel.
Video conferencing provides an additional tool to improve communications with multiple sites within a business, or with other businesses, in applications such as meetings, telecommuting, training, or services, which can all be enhanced through face-to-face communications. Businesses which operate multi-nationally, despite their physical location, can benefit from video conferencing.
Users also demand that solutions be standardized to enable interoperability, be easy to configure, use, and manage within the existing environment, and also meet purchase and operational cost targets. These examples show how video conferencing can help save operation costs, save time, and improve efficiency.
The Solution
The video conferencing needs of businesses is solved by providing LAN-based systems to the
users, and a router with an LAN to ADSL connection to the central office over the existing
copper loop. The ADSL router allows multiple users in the business to access the Internet
at speeds of 6.1M bits/sec, without the requirement of a dedicated leased-line or T1
connection.
In addition, the high throughput provided by an ADSL connection supports video conferencing and several other applications simultaneously such as web browsing, email, or additional video conference calls.
The Benefits
Video conferencing requires access to high speed communications media. ADSL is the optimum
media solution for video conferencing due to its ability to make use of the approximately
750 million lines currently available to virtually every location on the planet.
In addition, ADSL has the ability to adapt itself to the connection quality and offer between 1.5M and 6.1M bits/sec downstream from the network, and between 176K and 640K bits/sec upstream. This provides the bandwidth required in order to transfer the video and audio data for a video conference call.
ADSL uses the existing phone lines, which are unique point-to-point connections with users and the network. Therefore security for the conference is not compromised, and service will never degrade due to the sharing of the line with other users.
The fact that both the American National Standards Institute or ANSI and the International Telecommunications Union or ITU are driving the standardization of ADSL ensures that global interoperability will be a reality.
ADSL addresses the issues with providing video conferencing solutions to businesses by providing sufficient bandwidth over the existing wiring infrastructure. It is standardized by recognized international organizations. As with an Analog Modem, it is easy to install and configure, and operates within the normal environments of most business users today.
