Agenda l.jpg
Agenda

  • Video Conferencing, why now?

  • Questions to ask yourself

  • Components of a video network

  • Video Hardware

  • ISDN video conferencing

  • IP video conferencing


What is driving the growth of video conferencing l.jpg
What is driving the growth of Video Conferencing

  • Reduce Business Travel

    • 9-11

  • Business down turn

    • Save money

    • Increase production

  • Migration to IP is finally real

    • Can use the same network as the rest of data services.

Top applications in 2002 l.jpg
Top Applications in 2002

Application

Travel avoidance

Supplier/customer relationships

Distance Learning

Legal, Depositions & Partner meetings

Executive Recruiting

It is all about getting the right person

in the right place at the right time


What is your business need l.jpg

How do you train your employees?

HR?

New products?

New systems or procedures?

Are you happy with web training or teletraining?

What about your sales meetings?

How often do you meet face to face?

Would it help to meet more often?

Project planning meetings?

If you met more often and spent less time traveling, would you be able to get a product developed more rapidly?

How much new revenue do you think you could generate if you traveled less but met more often?

Meetings with key customers and suppliers?

Would it help to have better access to your suppliers?

Do you know if they have video conferencing?

Tell me about your travel policy and budget

Is your company under pressure to reduce expenses?

Has your travel budget been affected by the weakened economy?

Do you have any new security policies that affect business travel?

Have the new airport security measure impacted the productivity of your traveling employees?

Where does your travel department report into? Is that department interested in reducing expenses?

What is your business need?


Consider l.jpg

When was the last time you saw video conferencing?

The technology is constantly improving. If it has been > 1years, it is better, less expensive and easier to manage and use now.

Are most of your meetings internal or external?

Internal, you can utilize your existing IP network

External we offer a secure gateway that allows you to call to either ISDN or IP endpoints without investing in the hardware

What type of LAN/WAN network do you have in place?

Video can run effectively over MIS, ATM and IPeFR, as well as ISDN.

Public internet is not a business quality alternative.

Did you know that 84% of all video hardware is capable of either IP or ISDN calling?

You may not need to covert your existing video hardware, it could be IP capable today.

Consider…

Videoconferencing Network Components

H.320

  • Dedicated ISDN lines to

  • every end point

  • Predictable performance

  • Metered usage charges

H.323

  • Utilizes existing

  • infrastructure

    • LAN: Ethernet

    • WAN: IP

  • Higher fixed cost, but…

  • “All you can eat” WAN

ISDN

Isdn or h 320 l.jpg
ISDN or H.320

  • Cost

    • Usage sensitive pricing

    • Great for variable utilization

    • But,may not be the best choice for every desktop

  • Most widely used video network

    • Intercompany application

    • ISDN embedded base

    • Legacy H.320 hardware

  • Proven and reliable

    • Bandwidth has guaranteed performance


Ip or h 323 l.jpg
IP or H.323

  • Fixed costs

    • Forecast expenses

  • Allows for technology convergence

    • Integrates into data network infrastructure

    • IT staff can focus on a single network platform

    • Fits into network expansion plans

    • IP connectivity is on every desktop

    • Greater accessibility

  • New video hardware is IP capable

  • Allows better multimedia and data collaboration



The gateway choice l.jpg
The Gateway Choice

With a service provider

Within your own network

  • Who will assume responsibility for purchase, installation, configuration, maintenance, and troubleshooting of gateway equipment?

  • Who will plan for and design network for gateway placement?

Effect of latency jitter packet loss l.jpg
Effect of Latency, Jitter, & Packet Loss

What is the effect of...

  • Latency

    • Video lag time

    • Awkward conversation

    • Too much = packet loss

  • Jitter

    • Intermittent lag

    • Awkward conversation

    • Too much = packet loss

  • Packet loss

    • Image artifacts

    • Audio artifacts

    • Too much = video unusable

Delay < 150 ms. end-to-end

Jitter < 150 ms

Packet loss < 1-3%


How much bandwidth do you need l.jpg

How Much Bandwidth Do You Need?

Video Data Rate + 20% = Bandwidth Required

Video Data RateBW Required

128kbps = 153kbps

384kbps = 460kbps

At t belief system it is all about convergence l.jpg
AT&T Belief SystemIt is all about convergence

  • IP video conferencing will surpass ISDN within the next few years

  • Our customers do not want nor need to build a separate network for video conferencing.

  • We encourage our customers to invest in a high quality, high reliability network infrastructure and run their video over it.

  • We provide network based enablers that will seamlessly provide gateways between our networks and other users.

  • If our customers want to build their own gateway, we can help them engineer network and choose the right components.
