What is the AV Integrator Accreditation System?
Collaboration AV Integration partners are specialists in the development and implementation of custom communication environments. These environments combine TelePresence video codecs with non-Cisco Audio Visual solutions to provide an optimum experience for conference participants.These complimentary AV solutions could include:
• Electronic Whiteboards
• Video & Data displays
• Control Systems
• Lighting Systems
• Microphones & Speakers
• Furniture & Lecterns
• Streaming Media
• Sound Reinforcement
These environments can be found in almost any Enterprise or Commercial area, but specifically in these areas:
• Colleges & Universities
– Classroom Systems
– Distance Learning Systems
• Government operations in Federal,
State and Local
– Boardroom/Conference Room
– Training Room
– Command & Control Facilities
• Hotels & Convention Centers

Cisco AV Integrator Accreditation System
The Cisco AV Integrator Accreditation System (AVIAS) within the Cisco Developer Network (CDN) has been developed to create a framework for quantifying AV Integrators globally and promoting their use on Cisco projects.
How does it work?
• AV Integrators globally will agree to follow AV Industry best practices as outlined in the system
• Attainment of these best practices will place the AV Integrator on the CDN Search Engine
• As AV Integrators meet the requirements they will be earn one of three levels
• Agrees to follow InfoComm AV Installation Best Practices
• Attended training on the Cisco C-Series Integrator codecs
• Demonstrated basic ability to design & implement integrated AV Projects
• Completed 6 projects using AV9000 AV Industry standard commissioning checklists with a favorable end client endorsement
• Agrees to satisfactorily complete commissioning checklist on all Cisco projects
• Agrees to provide 8 x 5 support on all Cisco AV Integration projects
Preferred Solution Provider
• Implements an auditable Quality Management System on all AV projects with Cisco Collaboration solutions
• Agrees to use AV9000 Design, Staging and Commissioning checklists on all Cisco Collaboration solutions
• Agrees to provide 24 x 7 support on all Cisco AV Integration projects
Search for an AVIAS partner through the CDN System at http://marketplace.cisco.com/catalog and choose Cisco TelePresence /AV Integration on the left. Then enter the state or country of interest in the search box to find a local integrator.
The following specifications should be expected in any system developed and
commissioned by a Solution or Preferred Solution Developer in the AVIAS system.
Client Performance Specification
2.1.1 Anticipated ambient noise (dB-SPL, A wtd) 42 dB SPL
This is how “loud” the room will be without any source being distributed by the system. This noise is most likely from HVAC vents, outside rumblings, happenings outside the room, etc. For a very quiet conference room, the estimated level would
be about 35 dB SPL, and most boardrooms end up at around 40 dB SPL.
2.1.2 Target speech level 65 dB SPL
This is how “loud” any conferencing (audio, video, etc.) in the room will be set. Typical conversation level in a quiet room is about 65 dB SPL, but users of the room may want it alittle bit (~3 dB) louder or softer according to preference or hearing
2.1.3 Target Program level 68 dB SPL
This is how “loud” program material will be in the room. Program material includes DVD, CD, taped media, etc. Some users like to be “blown away” (85 dB SPL +) when watching or listening to program material, and others prefer it to be lower than the speech level, so conferences can be heard above any program material.
2.1.4 Head room level, speech
Head room deals with how loud the speech level CAN be when adjusted to full, and still be 10 dB free of distortion. Several customers prefer to keep a tight spectrum of levels so users cannot put the system into feedback. Other customers want the
ability and flexibility to have complete control over the system equipment.
2.1.5 Head room level, program 10 dB
Program headroom is slightly different from speech. There is less risk of feedback with program material. If the default level of program level is less than the conferencing level, users may want a large amount of headroom to still be “blown away” by the system.
2.1.6 Electrical signal to noise, all audio systems
Signal to noise is the difference in level between a signal level (something distributed) and 55 dB noise level (nothing distributed). Typical signal to noise ratio for a well installed system is about 55 dB. It could be very difficult (and expensive) to
get higher. However, various constraints (budget, space, equipment preference, etc.) may cause it to be less.
2.1.7 Approximate variance between program source audio levels +/- 1 dB
This is the difference in level when switching between sources (CD to DVD player to TV to etc.). Depending on the equipment, +/- 1 dB should be completely acceptable, and the difference in level at the variance will not be perceived by users.
2.1.8 Rapid Speech Transmission Index (RSTI) > 0.85
Any less than 0.85, and it will be tedious to understand the speech for some prolonged amount of time. However, this number may be compromised due to budget, special restraints, etc.
2.1.9 Wireless Microphones
Define the physical area where the wireless microphone transmitters are expected to operate drop out-free. Perform RF sweep to make sure they will work at proper frequency.(Encrypted, not encrypted, battery life, PTT, etc.)
2.1.10 Video level tolerance +/- 1 dB
Video level of the system is important to maintain. +/-1 dB will keep the video from blooming (>1 dB), or from appearing blurry (<1dB). However, this number may be compromised due to budget, special restraints, etc.
2.1.11 Display size (relative distance to furthest viewer) FV / 6
This equation determines how large the screen should be according to the distance to the furthest viewer. There are several factors to consider for this measurement, including how detailed the images displayed will be (PowerPoint is much easier to
see than maps or Excel spreadsheets). Also, the furthest viewer may not always be at the same point for each use. The recommended distance to the furthest viewer: (FV) divided by 6 for general viewing, however, users may sometimes prefer FV
divided by 5 to get a more detailed view of the image.
2.2.1 Targeted computer resolution(s)
This specification should be based on what most of your users will be using with the system. 1280 x 1024 It may also be wise to think about future technology trends, so your system stands the test of time. Add types supported: MAC, PC, Ipad, DVI, DP, etc.
This is how bright the projected image will be, which is determined by the size of the image 65 fc and the brightness of the projector. A projector will seem much brighter on a small screen than on a large screen (similar to spreading peanut butter: a scoop will seem very thick (bright) on a cracker, but pretty thin (dim) on a piece of bread). Recommendation: at least 65 fc for a typical conference room image, but users may prefer a different number.
Review the InfoComm STEP (Sustainable Technology Environments Performance) Committee’s recommendations in the Design kickoff meeting, and include sustainability issues throughout the needs analysis/programming, and include
consideration for each credit during the architectural/infrastructure design development stages as determined.
Are there “what if” issues to be determined when key equipment fails, or when communications services are disrupted, as in a regional disaster?
