Slide 15

Requirements for Good Quality Desktop Internet Videoconferencing 1. Quick PC. 300 MHz least. 450 MHz best. 2. Great quality feature conferencing hardware. Disregard “web cameras”. Disregard programming like Netmeeting. 3. Great Internet association. Most vast college systems are great. Disregard 56K modem dial-in. Link modems and DSL are conceivable.

Slide 16

Video Conferencing Products 1. Programming based Generally moderate and non-standard; not exceptionally acceptable. Illustrations: Microsoft NetMeeting, White Pine CUSeeMe. 2. Equipment based, plug into PC USB Port. Most up to date methodology; will get to be omnipresent Examples: Polycom ViaVideo, VCON ViGo. 3. Equipment based, PCI-transport cards introduce inside PC. Included components and controls, past USB frameworks. Samples: Zydacron Z340, VCON Escort 25. 4. Equipment based, standalone, no PC included. Most effortless to utilize, best quality. Samples: Polycom Viewstation 128, VCON Falcon

Slide 17

Recommended Equipment for Video Conferencing Desktop and Laptop: Polycom ViaVideo - cost $400 Also requires PC Classroom and gathering room: Polycom Viewstation - model 128 - Cost $4000 Also obliges TV screen or projector

Slide 20

Multipoint Control Unit (MCU) 1. Permits more than two individuals to be in a feature meeting. 2. May be physically found anyplace on Earth. 3. Capacities as an Internet server for feature conferencing. 4. Each person’s sound is constantly heard by all others. 5. Feature from the individual who talks loudest is seen by all. 6. Different brands have different limits and elements. 7. Different MCUs may be fell together for bigger feature meetings. Alternately utilized independently for more concurrent feature gatherings.

Slide 21

Hardware versus Software Multipoint Control Units: Hardware (Dedicated, Real-Time Operating System) Generally function admirably. RADVision (and false names Madge and CISCO) Lucent Accord Software (Windows NT Operating System in a PC) Usually don\'t function admirably. White Pine PictureTel

MCU Control Functions Defining a meeting velocity number of clients different windows Operating a gathering dial out dial in Monitoring a meeting Monitoring a MCU Cascading MCUs

Slide 24

Recommended MCUs RADVision MCU-323 9 ports at 384K. $18K Small and basic; incorporates watchman. RADVision ViaIP 50 ports at 384K $150K Powerful and solid; ECS guard Accord/Polycom NGK 48 ports at 384K $450K Many best in class includes; no watchman

Slide 25

Commons MCU Test Facility All three prescribed MCUs are accessible for testing and talk. Both remote and on location testing. Helpful for assessments and your own particular buys.

Slide 27

What is a Gateway An entryway unites an end point utilizing one system and/or convention to an end point utilizing an alternate system and/or convention. Samples: ISDN to IP or ATM (H.320 to H.323 or H.321) ISDN or IP to MPEG (H.32X to MPEG)

Slide 28

Gateway (GW) 1. Joins H.320 ISDN feature calls with H.323 Internet feature calls. 2. Calls may be started from either side. 3. May be physically found anyplace on Earth. 4. Different brands have different limits and elements. 5. Different portals may be utilized for more synchronous calls.

Slide 29

Gateway (GW) Specific sample: RADVision L2W-323 1. Up to 4 synchronous feature calls; 384K each. 2. Fabricated in telnet server. Gives discretionary remote control and checking. 3. Adjustable voice reaction. 4. PC remote setup programming. Gives parameter settings and programming redesigns. 5. Taken a toll about $5K in addition to $1500/2BRI and $800/2V.35

Examples of Gateways Build-It-Yourself Gateway In A Box Gateway Feature of the MCU

Slide 31

Build-It-Yourself Gateway sound MPEG codec I2 or IP H.323 ATM MPEG H.323 codec (could be ISDN H.320, and so forth.) feature

Slide 32

Build-It-Yourself Gateway Pros Cost funds for low use, utilizes codecs that may be as of now accessible. Can be on a switch or patch cove so codecs can be effectively repurposed for classroom use when not performing door capacities. Valuable for non-H.32X systems, for example, MPEG

Slide 33

Build-It-Yourself Gateway Cons Needs administrator for active calls. No far-end camera control interpretation, hangup, and so forth. No T.120 interpretation, must utilize option, for example, web meeting to team up.

Slide 34

PSTN ISDN ATM IP Gateway In A Box H.324 H.320 Gateway H.323 H.321

Slide 35

Gateway In A Box Pros Protocol interworking of control and media streams between a H.Series end point with another H.Series end point or voice band end point. Approaching and active call bolster utilizing Gatekeeper to interpret telephone number. Far end camera control may be upheld. T.120 upheld if end focuses bolster, else utilization web. GK and GW are frequently in the same box for simple administration.

Slide 36

Gateway In A Box Cons Limited items accessible supporting interpretation to non-H.32X systems, for example, MPEG or simple. Non-H.32X frequently obliges a custom frame setup, as utilized on Wisconsin’s K-12 Motion-JPEG system to passage to H.32X.
