Editor's Notes
- #3 ANSI - The American National Standards Institute (ANSI) is a private, non-profit organization that administers and coordinates the standardization and conformity assessment system. Founded in Oct. of 1918. EIA – Electronic Industries Alliance is a national trade organization that includes the partnership of electronic and high-tech associations and companies. 2,500 member companies like Cisco 3Com Nortel etc. TIA – Telecommunications Industry Associations - represents the providers of communications and information technology products and services. They write the telecommunication standards with EIA. Formed in 1988. BICSI (Buidling INDUSTRY CONSULTING SERVICES INTERNATIONAL) WRITES THE TELECOMMUNICATIONS INDUSTRY DESIGN STANDARDS AND PROVIDES TRAINING AND MANY CERTIFICATIONS WITHIN THE INDUSTRY . FOUNDED IN 1974, CURRENTLY OVER 25000 MEMBER IN 90+ COUNTRIES
- #4 RCDD – AN RCDD has attained exceptional excellence in the telecom industry and the RCDD designation is recognized industry-wide as indicating superior design expertise. RCDDs must attain CEC to stay ahead of any technology changes. Other BICSI Certification OSP NTS Installer TLT - An act concerning telecommunications infrastructure layout technicians and the registration of employees of telecommunications providers. First of four states (Connecticut, Minnesota, New Jersey and Rhode Island) in the USA to be licensed for design. The TLT license gives the RCDD the ability to stamp telecommunication drawings.
- #5 To ensure that telecommunication systems are "designed into" a building during the design phase of the project versus the more traditional method of "retrofitting" it into the building 25 – Integrated Automation Terminal Devices for Facility equip., fire suppression systems, plumbing, HVAC, Electrical, Communication 27 – Communication Structure Cabling including horizontal and backbone Data communication hardware and network equipment including peripherals and software Voice communication hardware AV communications systems 28 - Electronic Safety and Security Intrusion Detection Access Control Electronic Surveillance ALL OF ABOVE IS LOCATED IN FACILITY SERVICES SUBGROUP ALONG WITH HVAC PLUMBING AND ELECTRICAL
- #6 With the previous Maserformat changes the industry has changed the following terms. MDF and IDF old AT&T terms The reason for changing the phrase telecommunications is its no longer just voice and data running over the low voltage cable infrastructure.
- #7 NOW LETS TALK ABOUT THE 3 MAIN ROOMS FOR TELECOMMUNICATION EQUIPMENT AND CABLING Local Area Network and Private Branch Exchange (PBX)
- #8 1. MER housed equipment that serves the entire organization or building. The equipment within the MER is very complex in nature.
- #9 THE ITR HOUSES EQUIPMENT THAT IS FLOOR SERVING ONLY
- #10 NOW LETS TALK ABOUT HOW INFO IS TRANSFERRED OVER THE FIBER. DATA TRANSFER RATE IS THE AMOUNT OF DATA THAT CAN TRAVEL FROM ONE POINT TO ANOTHER, ITS EXPRESSED IN BITS PER SECOND AND REFERS PRIMARILY TO THE CAPABILITY OF THE ELECTRONICS MEGA – MILLION GIGA - BILLION 40 Gbe IS AROUND THE CORNER WITH THESE SPEED INCREASES IT’S GOTTEN TO THE POINT THAT TECHNOLOGIES ARE REALLY PUSHING THE LIMITS OF THE FIBER OPTIC CABLE. NOTE – TECHNOLOGY USUALLY INCREASES 10X
- #11 Integrating data, email, fax, voice and video-conferencing into one network is the basis of convergence technologies. Benefits of Convergence ONE NETWORK – NO NEED TO MANAGE SEPARATE VDV NETWORK WHICH PRESENTS COST SAVINGS. ONE IT DEPT. COST EFFICIENT SERVICES FLEXIBILITY DESIGNERS NEED TO BE AWARE THAT SOME CONVERGED TECHNOLOGIES WILL NOT RUN WITH SOME OF THE CURRENT TRANSMISSION PROTOCOLS
- #12 Let now talk about the types of cabling and whats run over them. FIBER DISTANCES CAN RANGE FROM 10 METERS TO 10 KILOMETERS SO THE PROPER SELECTION OF F/O CABLE WITH RESPECT TO NETWORK SPEEDS IS A MAJOR CONSIDERATION.
- #13 AS DISCUSSED ON THE LAST SLIDE THE TRANSMITTER TYPE AND THE TRANSMITTED WAVELENGTH EFFECT THE FIBER DISTANCE CAPABILITIES TRANSMITTER CONVERTS ELECTRICAL SIGNAL TO LIGHT THE TRANSMITTERS EMIT LIGHT AT A SPECIFIC WAVELENGTH. THE HIGHER THE WAVELENGTH THE FURTHER THE DISTANCE AND MORE BANDWIDTH IS AVAILABLE.
- #14 Cat3 still used for voice – primarily in the horizontal Cat5 is now obsolete CAT5e Very large installed base – Contractor knowledgeable Quick terminations and testing LESS STRINGENT INSTALLATION REQUIREMENTS Capable of running Gbe Cannot handle 10Gbe Will not be manufactured, both cable or connector Will become obsolete when 7 is standardized
- #15 BANDWIDTH IS THE INFORMATION CARRYING CAPACITY OF A SYSTEM AND IS MEASURED IN Mhz. FIBER – BANDWIDTH IS A EXTREMELY COMPLEX MATHMATICAL EQUATION COPPER – YOU GET WHAT YOU GET WITH COPPER, THE BANDWIDTH OF COPPER IS REALLY PUSHED TO THE LIMITS WITH TODAYS TECHNOLOGIES SPEEDS ARE INCREASING MORE RAPIDLY THAN THE BANDWIDTH CAN ACCOMODATE, THUS PUSHING THE CABLE INFRASTRUCTURE TO ITS LIMITS
- #16 The minimum standard compliant cable today CAT5e Very large installed base – Contractor knowledgeable Quick terminations and testing LESS STRINGENT INSTALLATION REQUIREMENTS Capable of running Gbe Cannot handle 10Gbe Will not be manufactured, both cable or connector Will become obsolete when 7 is standardized
- #17 NOW LETS GET INTO SOME OF THE NEWER TECHNOLOGIES A Wireless LAN (WLAN) is a grouping of network components connected by electromagnetic (radio) waves instead of wires. Mobile- you can move around reliable - fewer wires and connectors means fewer problems ease of install - fewer cables to install, one cable per access point location affordability - installation and product life cost are lower scalability - easily configured and rearranged to meet many settings and # of users SECURITY – INFORMATION IS IN THE AIR AND HACKERS ARE FREE TO ACCESS IT. SPEEDS - SLOW AND SHARED
- #18 802.11a 54 Mbps at the 5Ghz frequency – SAME AS CORDLESS PHONES 8 separate non overlapping channels 802.11b 11 Mbps at the 2.4 Ghz frequency 3 nonoverlapping chanells 11a and 11b are not compatible, separate networks 802.11g – NEWEST TECHNOLOGY Extension of 11b STANDARD 54 Mbps at the 2.4 Ghz frequency Backward compatible with 11b meaning device with a 11b card will interface with an 11g access point at 11 Mbps or lower 802.11n Standard end of 05 early 06 Product mid 06 100 Mbps or faster Spread sprectrum Frequency hopping
- #19 QOS - DEFINE NEEDED WITHIN THE DATA HARDWARE INFRASTRUCTURE COSTLY UPGRADE ADVANTAGES LOWER COSTS PER CALL - IP TELEPHONY / BUILDING TO BUILDING LOWER INFRSTRUCTURE COSTS ONE CABLE INFRASTRUCTURE MOVES ADDS AND CHANGES ARE VERY SIMPLE – THE PHONES HAVE IP ADDRESS UNIFIED MESSAGING CONNECTS WORKERS TO VOICE MAIL, EMAIL, FAX WHENEVER THEY NEED THEM FROM ANY DEVICE, CELL PHONE, PDA, LAPTOP DISADVANTAGES: VERY DIFFICULT IMPLEMENTATION NETWORK OUTAGES VIRUS PROBLEMS OTHER TECHNOLOGIES WILL NOT RUN WITH VOIP Gbe AND 10Gbe
- #20 WHITEBOARDS DIFFERENT CONNECTOR TYPES PER MANUFACTURER DIFFERENT MOUNTING ARRANGMENTS THAT EFFECT THE LOCATION ON THE PRESENTATION WALL DISTANCE LEARNING REQUIRES HIGH SPEED WAN CONNECTIVITY HIGH TECH VIDEO AND SOUND SYSTEMS PROJECTORS TODAYS PROJECTORS CAN BE NETWORKED FOR CATV AND VIDEO PRESENTATION. THEY ALSO HAVE THE CAPABILITY OF REMOTE MONIORING AND EMAIL NOTIFICATION.
- #21 MEDIA RETRIEVAL SYSTEM – VIDEO HEADEND SYSTEM WITH THE CAPABILITY OF TRANSMITTING CD/DVD OR BROADCAST VIDEO OVER THE UTP INFRASTRUCTURE. LARGE A/V ROOM FULL OF EQUIPMENT. IN A SCHOOL ENVIRONMENT THE PRINCIPAL CAN MAKE MORNING MESSAGES OVER THE TV OR PROJECTOR, VCR AND DVD’s ARE NOT REQUIRED IN ANY CLASSROOMS SECURITY TODAYS CAMERAS ARE RUN OVER THE UTP INFRASTRUCTURE GIVING THEM THE CAPABILITY OF UTULIZING POWER OVER ETHERNET NETWORK CONNECTIVITY GIVES THE SECURITY STAFF ACCESS TO THE MEDIA RETRIEVAL SYSTEM AND DVR”s. RECORDING IS DONE ON THE HARD DRIVE, IS EASIER AND QUICKER TO ACCESS THAN A VHS TAPE SPECIALTY SYSTEMS - EXPLAIN
- #22 THE ABILITY TO RUN POWER OVER 2 OF THE PAIRS OF THE UTP CABLE Midspan – a separate device injects power onto the unused pair UP TO 48 VOLTS
- #23 10 YEARS AGO THROWING IN A CAT5 UTP CABLE WOULD BE SUFFICIENT TO HANDLE THE TRANSMISSION SPEEDS AND TECHNOLOGIES OF THE DAY. THE DESIGNER NEEDS TO BE AWARE OF WHAT TECHNOLOGIES ARE TO BE RUN ON THE CABLE INFRASTRUCTURE BECAUSE CERTAIN TECHNOLOGIES ARE NOT COMPATIBLE AND IF THEY DO NOT HAVE THE APPROPRIATE CABLE AND OR ELECTRONICS THE SYSTEM WILL NOT FUNCTION AS DESIRED VARYING DISTANCES WITHIN THE BACKBONE AND CAMPUS ENVIRONMENTS 3 WINDOWS OF TRANSMISSION THEY BOTH UTULIZE ALL 4 PAIRS OF THE UTP CABLE UTULIZES THE 2 UNUSED PAIRS YOU CAN’T RUN GBE OR HIGHER IN THE HORIZONTAL VOIP CANT RUN GBE OR HIGHER EFFECTS BACKBONE DESIGN (NO COPPER BACKBONE)
