SSSSTRUCTURED NETWORK CABLINGTRUCTURED NETWORK CABLINGTRUCTURED NETWORK CABLINGTRUCTURED NETWORK CABLING GeoVision Limited is appointed as an authorized installer for the Structured Cabling Systems and as such appointed for the System warranty program. This program gives a warranty of 15-20 years for structured cabling installations designed and installed by Geovision Limited. Geovision has proposed a total solution for all the cabling products, both copper and fiber Optic.

Our Structured Cabling System is a complete package of products that includes:

1. Design, 2. Engineering 3. Installation services for customer premises wiring. As part of the our Structured Cabling System, the UTP CAT 6 plus Product Family exceeds the highest measure of performance available over Category 6 unshielded twisted pair (UTP) cable. Individually, these products perform substantially above industry standards for Category 6 applications. Installed as Structured Cabling System, the CAT 6 Product Family assures maximum performance over your entire network because this is the only comprehensive collection of products specifically designed and manufactured by the same vendor to complement each other in premises networking applications. It is important to note that Geovision installs comprehensive cabling systems based on internationally recognized standards and not a mere discrete group of components that have never being tested together as a system.

The Structured cabling system consists of the transmission network inside a building or campus of buildings. It connects voice and data communications, video and building automation devices, switching equipment and other information management systems to one another as well as to outside communications networks. It includes all the cabling and associated distribution components between the point where the building wiring connects to the outside network or Telephone Company lines and the voice, data and video terminals at work locations. The system also serves a building or group of buildings on a campus-like premise.

Our Structured cabling system consists of various families of components, including transmission media, circuit administration hardware, connectors, jacks, plugs, adapters, transmission electronics, electrical protection devices and support hardware. These components are used to build elements, each having a specific purpose that allows easy implementation and smooth transition to enhance distribution technology as the communications requirements change. Structured cabling system is independent of the equipment it serves and is capable of interconnecting many different devices,

2010


including data terminals, analog and digital telephones, personal computers and host computers, security systems, as well as system common equipment.

Structured Cabling System presents the following advantages.

1. It has an open architecture allowing for easy expandability. Structured cabling system is modular, designed with growth and rearrangement in mind. It uses a star topology and conforms to EIA/TIA 568A /B Commercial Building Standard.

2. Structured Cabling System adheres to local and international standards

3. Structured Cabling System is a total solution without requiring components from other manufacturers.

STAR TOPOLOGYSTAR TOPOLOGYSTAR TOPOLOGYSTAR TOPOLOGY

The star topology of our structured cabling system can be broken down into the following subsystems.

1. Horizontal Cabling subsystem consisting the horizontal wiring from the administration points to the telecommunications outlet. The media commonly used is CAT 5/CAT6 UTP or fiber optic cable (fiber to the desk) 2. Backbone cabling subsystem consisting of the connections between administration points within a building or within a campus setup. 3. Work Area subsystem consisting of the telecommunications outlets and the patch cables used to connect terminal equipment to the Telecommunications outlets. 4. Administration subsystem consisting of patch panels and patch cords. It is used to connect the horizontal and backbone subsystems to the active Network devices like switches. 5. Equipment Room subsystem consisting of Cabinets, air conditioning and associated equipment.

Horizontal Cabling We install our horizontal solutions based on CAT 6 PLUS UTP cabling capable of transmitting data up to 1000 Mbps therefore offering support for Gigabit Ethernet to the desktop in the future should the AFC require to move in this direction. . It uses a star topology and conforms to ANSI/EIA/TIA-568B and ISO 11801 Commercial Building Standards.

During installation, the UTP cables will:

2010


BE installed so that they can move if pulled firmly NOT be crushed using cable ties NOT be overfilled in the conduits BE installed in the trucking and will not be seen outside the trunkings NOT be joined or spliced

In addition;

5 user patch cords on each wing will be 5 meters long with the balance being 3 meters catering for any workstation requiring long patch cords. Data outlets shall be flush mounted on the trunking. A double faceplate will be installed configured with two modules for data and voice.

BACKBONE CABLINGBACKBONE CABLINGBACKBONE CABLINGBACKBONE CABLING

Geovision Limited back-bone cabling installation is based on 8-core 50/125um multimode fiber Optic cables for the data backbone. All the strands will be terminated at each end of the cable.

The fiber cable proposed has sufficient bandwidth capacity that will support current system requirements and also support future system requirements. The fiber has initially been configured to support Gigabit Ethernet. The fiber cable will be protected from external interference by use of Metal conduits to be installed in the riser.

The proposed solution will offer easy administration and superior performance by following design and installation guidelines as indicated below;

Deployment of fiber optic patch panels and patch cords at all the administration points.

The Multimode fiber optic cables will be terminated on multimode SC. This will ensure uniform continuity of the fiber core from end to end avoiding unnecessary signal loss. Fiber Optic cables will be terminated using the Hot Melt method of termination. Hot Melt termination is the modern way of terminating fiber optic cables

ROUTINGROUTINGROUTINGROUTING

In computer networking the term routing refers to selecting paths in a computer network along which to send data.

Routing directs forwarding, the passing of logically addressed packets from their source network, toward their ultimate destination through interrouters. The routing process usually directs forwarding on the basis of routing tables which maintain a record of the best routes to various network destinations. Thus constructing routing tables, which are held in the routers' memory, becomes very important for efficient routing.

Routing differs from bridging in its assumption that addresssimilar addresses within the network, thus allowing a single routingroute to a group of addresses. Therefore, routing outperforms bridging in large networks, and it has become the dominant form of path

Traditional IP routing stays relatively simple because it uses nextneeds to consider where it sends the packet, and does not need to consider the subsequent path of the packet on the remaining hops.

ministrative security to

2010


Generally, a firewall sits between a remote user's workstation or client and the host network or server. As the user's client establishes the communication with the firewall, the client may pass authentication data to an authentication service inside the perimeter. A known trusted person, sometimes only when using trusted devices, can be provided with appropriate security privileges to access resources not available to general users.

Many VPN client programs can be configured to require that all IP traffic must pass through the tunnel while the VPN connection is active, for increased security. From the user's perspective, this means that while the VPN connection is active, all access outside the secure network must pass through the same firewall as if the user were physically connected to the inside of the secured network. This reduces the risk that an attacker might gain access to the secured network by attacking the VPN client's host machine: to other computers on employee’s home network, or on the public internet, it is as though the machine running the VPN client simply does not exist. Such security is important because other computers local to the network on which the client computer is operating may be untrusted or partially trusted. Even with a home network that is protected from the outside internet by a firewall, people who share a home may be simultaneously working for different employers over their respective VPN connections from the shared home network. Each employer would therefore want to ensure their proprietary data is kept secure, even if another computer in the local network gets infected with malware. And if a traveling employee uses a VPN client from a Wi-Fi access point in a public place, such security is even more important. However, the use of IPX/SPX is one way users might still be able to access local resources.

Types of VPN:

Secure VPNs use cryptographic tunneling protocols to provide the intended confidentiality (blocking snooping and thus Packet sniffing), sender authentication (blocking identity spoofing), and message integrity (blocking message alteration) to achieve privacy. When properly chosen, implemented, and used, such techniques can provide secure communications over unsecured networks. This has been the usually intended purpose for VPN for some years.

2010


Because such choice, implementation, and use are not trivial, there are many insecure VPN schemes available on the market.

Secure VPN technologies may also be used to enhance security as a "security overlay" within dedicated networking infrastructures

Secure VPN protocols include the following:

IP sec (IP security) - commonly used over IPv4, and an obligatory part of IPv6. SSL/TLS used either for tunneling the entire network stack, as in the OpenVPN project,

or for securing what is, essentially, a web proxy. SSL is a framework more often associated with e-commerce, but it has been built-upon by vendors like Aventail and Juniper to provide remote access VPN capabilities. A major practical advantage of an SSL-based VPN is that it can be accessed from any public wireless access point that allows access to SSL-based e-commerce websites, whereas other VPN protocols may not work from such public access points. Open VPN, an open standard VPN. Clients and servers are available for all major

operating systems. PPTP (Point-to-Point Tunneling Protocol), developed jointly by a number of companies,

including Microsoft. L2TP (Layer 2 Tunneling Protocol), which includes work by both Microsoft and Cisco. L2TPv3 (Layer 2 Tunneling Protocol version 3), a new release. VPN Quarantine The client machine at the end of a VPN could be a threat and a source of attack; this has no connection with VPN design and is usually left to system administration efforts. There are solutions that provide VPN Quarantine services which run end point checks on the remote client while the client is kept in a quarantine zone until healthy. Microsoft ISA Server 2004/2006 together with VPN-Q 2006 from Winfrasoft or an application called QSS (Quarantine Security Suite) provide this functionality.

2010


MPVPN (Multi Path Virtual Private Network). MPVPN is a registered trademark owned by

Ragula Systems Development Company. See Trademark Applications and Registrations Retrieval (TARR) Some large ISPs now offer "managed" VPN service for business customers who want the security and convenience of a VPN but prefer not to undertake administering a VPN server themselves. In addition to providing remote workers with secure access to their employer's internal network, other security and management services are sometimes included as part of the package. Examples include keeping anti-virus and anti-spyware programs updated on each client's computer.

Trusted VPNs do not use cryptographic tunneling, and instead rely on the security of a single provider's network to protect the traffic. In a sense, these are an elaboration of traditional network and system administration work.

Multi-Protocol Label Switching (MPLS) is often used to build trusted VPN. L2F (Layer 2 Forwarding), developed by Cisco, can also be used.

Mobile VPN – A secure remote access solution designed for mobile and wireless users. A Mobile Virtual Private Network (Mobile VPN) integrates standards-based authentication and encryption technologies to secure data transmissions to and from devices and to protect networks from unauthorized users. Designed for wireless environments, Mobile VPNs are designed as an access solution for users that are on the move and require secure access to information and applications over a variety of wired and wireless networks. Mobile VPNs allow users to roam seamlessly across IP-based networks and in and out of wireless coverage areas without losing application sessions or dropping the secure VPN session. For instance, highway patrol officers require access to mission-critical applications in order to perform their jobs as they travel across networks.

Wireless LAN solutions One type of wireless network is a wireless LAN, or Local Area Network. Similar to other wireless devices, it uses radio instead of wires to transmit data back and forth between computers on the same network as was the case for ALOHANET.

Global Systems for Mobile Communications (GSM)

The GSM network is divided into three major systems which are the switching system, the base station system, and the operation and support system (Global System for Mobile Communication (GSM)). The cell phone connects to the base system station which then connects to the operation and support station; it then connects to the switching station where the call is transferred where it needs to go (Global System for Mobile Communication (GSM)). This is used for cellular phones, is the most common standard and is used for a majority of cellular providers. Personal Communications Service (PCS) PCS is a radio band that can be used by mobile phones in North America. Sprint happened to be the first service to set up a PCS. D-AMPS D-AMPS, which stands for Digital Advanced Mobile Phone Service, is an upgraded version of AMPS but it is being phased out due to advancement in technology. The newer GSM networks are replacing the older system.

Wi-Fi Wi-Fi is a commonly used wireless network in computer systems which enable connection to the internet or other machines that have Wi-Fi functionalities. Wi-Fi networks broadcast radio waves that can be picked up by Wi-Fi receivers that are attached to different computers.

Fixed Wireless Data Fixed wireless data is a type of wireless data network that can be used to connect two or more buildings together in order to extend or share the network bandwidth without physically wiring the buildings together

LAN SWITCHINGSWITCHINGSWITCHINGSWITCHING

Layer 2 switching Layer 2 switching is hardware based, which means it uses the media access control address (MAC address) from the host's network interface cards (NICs) to decide where to forward frames. Switches use application-specific integrated circuits (ASICs) to build and maintain filter tables (also known as MAC address tables). One way to think of a layer 2 switch is as a multi port bridge.

2010


Layer 2 switching provides the following:

Hardware-based bridging (MAC) Wire speed High speed Low latency Low cost Layer 2 switching is highly efficient because there is no modification to the data packet, only to the frame encapsulation of the packet, and only when the data packet is passing through dissimilar media (such as from Ethernet to FDDI). Layer 2 switching is used for workgroup connectivity and network segmentation (breaking up collision domains). This allows a flatter network design with more network segments than traditional 10BaseT shared networks. Layer 2 switching has helped develop new components in the network infrastructure:

SERVER FARMS

Servers are no longer distributed to physical locations because virtual LANs can be created to create broadcast domains in a switched internet work. This means that all servers can be placed in a central location, yet a certain server can still be part of a workgroup in a remote branch, for example. Intranets - Allows organization-wide client/server communications based on a Web technology. These new technologies are allowing more data to flow off of local subnets and onto a routed network, where a router's performance can become the bottleneck.

Limitations of layer 2 switching Layer 2 switches have the same limitations as bridge networks. Remember that bridges are good if a network is designed by the 80/20 rule: users spend 80 percent of their time on their local segment.

Bridged networks break up collision domains, but the network remains one large broadcast domain. Similarly, layer 2 switches (bridges) cannot break up broadcast domains, which can cause performance issues and limits the size of your network. Broadcast and multicasts, along with the slow convergence of spanning tree, can cause major problems as the network grows. Because of these problems, layer 2 switches cannot completely replace routers in the internet work.

2010


Layer 3 switching The only difference between a layer 3 switch and a router is the way the administrator creates the physical implementation. Also, traditional routers use microprocessors to make forwarding decisions, and the switch performs only hardware-based packet switching. However, some traditional routers can have other hardware functions as well in some of the higher-end models. Layer 3 switches can be placed anywhere in the network because they handle high-performance LAN traffic and can cost-effectively replace routers. Layer 3 switching is all hardware-based packet forwarding, and all packet forwarding is handled by hardware ASICs. Layer 3 switches really are no different functionally than a traditional router and perform the same functions, which are listed here:

Determine paths based on logical addressing Run layer 3 checksums (on header only) Use Time to Live (TTL) Process and responds to any option information Can update Simple Network Management Protocol (SNMP) managers with Management Information Base (MIB) information Provide Security

The benefits of layer 3 switching include the following:

Hardware-based packet forwarding High-performance packet switching High-speed scalability Low latency Lower per-port cost Flow accounting Security Quality of service (QoS)

2010


Layer 4 switching Layer 4 switching is considered a hardware-based layer 3 switching technology that can also consider the application used (for example, Telnet or FTP).

Layer 4 switching provides additional routing above layer 3 by using the port numbers found in the Transport layer header to make routing decisions.

These port numbers are found in Request for Comments (RFC) 1700 and reference the upper-layer protocol, program, or application.

Layer 4 information has been used to help make routing decisions for quite a while. For example, extended access lists can filter packets based on layer 4 port numbers. Another example is accounting information gathered by Net Flow switching in Cisco's higher-end routers.

The largest benefit of layer 4 switching is that the network administrator can configure a layer 4 switch to prioritize data traffic by application, which means a QoS can be defined for each user.

For example, a number of users can be defined as a Video group and be assigned more priority, or band-width, based on the need for videoconferencing.

However, because users can be part of many groups and run many applications, the layer 4 switches must be able to provide a huge filter table or response time would suffer. This filter table must be much larger than any layer 2 or 3 switch. A layer 2 switch might have a filter table only as large as the number of users connected to the network may be even less if some hubs are used within the switched fabric. However, a layer 4 switch might have five or six entries for each and every device connected to the network. If the layer 4 switch does not have a filter table that includes all the information, the switch will not be able to produce wire-speed results.

Multi-layer switching (MLS) Multi-layer switching combines layer 2, 3, and 4 switching technologies and provides high-speed scalability with low latency. It accomplishes this high combination of high-speed scalability with low latency by using huge filter tables based on the criteria designed by the network administrator.

2010


Multi-layer switching can move traffic at wire speed and also provide layer 3 routing, which can remove the bottleneck from the network routers. This technology is based on the idea of route once, switch many. Multi-layer switching can make routing/switching decisions based on the following:

MAC source/destination address in a Data Link frame IP source/destination address in the Network layer header Protocol filed in the Network layer header Port source/destination numbers in the Transport layer header There is no performance difference between a layer 3 and a layer 4 switch because the

routing/switching is all hardware based

PROPOSED WORKPLAN FOR DESIGN OF STRUCTURED PROPOSED WORKPLAN FOR DESIGN OF STRUCTURED PROPOSED WORKPLAN FOR DESIGN OF STRUCTURED PROPOSED WORKPLAN FOR DESIGN OF STRUCTURED CABLINGCABLINGCABLINGCABLING

Designing a Structured Cabling System.

Step 1: Which group of standards will we conform to?

European Union CENELEC EN standards America ANSI/TIA/EIA standards Canada CSA standards Australia/New Zealand AS/NZ standards Rest of the World ISO/IEC standards

The three principle design standards give the details of how to design and specify a structured cabling standard, they are;

• ISO 11801 • EN 50173 • TIA/EIA 568-A or 568-B

BICSI - these standards in turn however refer to hundreds of other standards relating to component specifications, fire performance, testing methods, containment systems etc.

Step 2: Horizontal cabling - Basic rules

Four-pair cables are run from user positions to a patch panel. At the patch panel, patch cords link into the active LAN equipment or into backbone cabling. The user position has a wall outlet or floor outlet, and this links into the PC on your desk via another patch cord. The outlet is a called a TO (Telecommunications Outlet) and contains an eight way plug meeting IEC 60603-7, more commonly referred to as an RJ-45.

• Two data and voice outlets per work area for each data point. • Two outlets per 10 square meters of useable floor space • Outlets to be within 3 meters of the user station • Both outlets to be RJ 45 • Max cable run to be 150 m • Max total length of patch cords at both ends of the link to be 5 m • Cable and RJ45 to be Cat6 plus grade

2010


Options

Cat 6 plus or optical fibers can be used

If optical fiber, select 8 core 50/125 um or 62.5/125 multimode

If using fiber select SC or ST connectors

Cat 6plus/Class E can be specified

Cat 6plus Cable can be unscreened, UTP, Foil screened, FTP, or Foil and Braid screened S-FTP.

Cable fire performance will be:

1. IEC 332-1 2. IEC 332-1, IEC 754, IEC 1034 3. IEC 332-3-c. IEC 754, IEC 1034 4. UL 910 plenum

Each grade, in ascending order, has a better performance in fire situations

Step 3: Backbone Cabling

All of the horizontal cables are star-wired back to Telecommunications Closets or Floor Distributors where they are terminated in patch panels. These patch panels are connected together via the building backbone cabling which can be up to 500 meters long.

It can be copper cable but is more likely to be optical fiber, either multimode or single mode. The kind of cables and the number of cores needs to be decided. If fiber is chosen, a loss budget should help you make your decision

Step 4: Campus Cabling

The campus cabling links different buildings together. It can be up to 1500 m long. It can be copper cable but is more likely to be optical fiber, either multimode or single mode. The kind of cables and the number of cores needs to be decided.

2010


Step 5: Positioning and design of Telecommunications Closets to link horizontal and

backbone cabling.

Positioning and design of the equipment room as a central focus for the main computing, LAN and PABX equipment.

Positioning and design of the Service Entrance facility whereby outdoor cables are terminated and the point of demarcation between customers owned equipment and the PTT cables is defined.

Step 6: Cable containment system

How will the cables be protected? Within buildings the choices are:

• Cable trays • wire basket/raceway • cable ladders • J hooks • conduit • dado rails • 150mm * 50mm Metal trunkings • raised floors • suspended ceilings

The following must be taken into account:

• the density and volume of cables to be organized • the aesthetic appearance of the cabling within offices and other visible areas • economics of different schemes • proximity to power cables and other potential sources of interference • fire stopping

Useful standards are:

• TIA/EIA 569 Commercial building standard for telecommunications pathways and spaces

• EN 50174 Information technology – cabling installation

For external applications the choices are:

• underground cable ducts • direct buried cable trench • concrete cable trough • self supporting aerial cable • supported aerial cable, i.e. catenary or messenger wire • fixed to building exteriors •

In all cases, we will ensure that all civil work has been carried out, rights of way established and availability of cable ducts and manholes established.

2010


Step 7: Cable Administration system

The cabling and its containment system will be clearly identified and their locations, routes and capabilities recorded in a cable administration system. This usually involves a logical numbering scheme that can be applied to all cables, outlets, patch panels and even containment systems. Various color schemes are also available.

These schemes can be paper based but for the larger installations then a computer based system is advisable. There are several proprietary solutions on the market which offer various database and graphical methods for keeping track of cabling assets. Some systems are also active in that they can detect moves and changes and automatically update the database.

Useful standards are:

• TIA/EIA-606 Administration standard for the telecommunications infrastructure of commercial buildings • EN 50174 Information technology – cabling installation

Step 8: Earthing Scheme

All exposed metallic elements of the cable system and cable containment system will be earthed (grounded) for safety and also electromagnetic compatibility requirements. If screened cables are used then special attention must be given to effective bonding of the screening elements. Poorly earthed screened cabling may behave worse than unscreened cabling.

An electrically ‘clean’ earth must be available at all points where the cabling is terminated, but especially within telecommunication closets, equipment rooms and service entrances. A clean earth is usually defined as a conductive element with not more than 1 volt rms potential difference between it and the real earth down below. Copper cabling linking two different buildings can suffer from earth loops if the ground potential is different. Non-metallic optical cabling is usually picked for problem areas such as these.

Some useful standards are:

• PrEN50303 Application of equipotential bonding and earthing at premises with information technology equipment

• PrEN50174-2 Information Technology, Cabling installation, part 2, Installation, planning and practices inside buildings

• TIA/EIA-607 Commercial Building Grounding and Bonding Requirements for Telecommunications

2010


Step 9: Testing regime

All cables are tested to demonstrate compliance with the standards and specification to which they were bought. Testing can be split into copper cable testing and optical fiber testing. Ideally all cables are 100% tested.

Copper cables.

There are manufacturers of hand held copper cable testers that will automatically test the installed cable plant for all the expected parameters. By the use of a remote injector, the cabling is tested from both ends, which is a condition of the standards. The cabling has to pass all of the suite of tests to be awarded and overall pass. Points to remember are;

What is being tested? The channel (i.e. end-to-end including all the patch cords) or the basic link (i.e. the permanently installed cable from outlet to patch panel). The test figures are different for each setting. It is usually more practical to test the basic link (also referred to as the permanent link).

What level is being tested? The tester should normally be set to Cat6plus.

The results are stored electronically and must be in a format recognizable by the cable management software that comes with the tester. There are now numerous test standards and draft standards. The most influential is likely to be;

IEC 61935 Generic specification for the testing of balanced generic cabling in accordance with ISO/IEC 11801

The tests required are; IEC 61935 Wire Map X Attenuation X; NEXT pair to pair X; NEXT Power sum X; ELFEXT air to pair X; ELFEXT Power sum X; Return Loss X; Propagation Delay X; Delay Skew X;DC Loop Resistance X. Cable length and ACR are also useful additions to this set of tests.

Optical cables

All that needs to be tested with short distance multimode optical cables is attenuation. This can be achieved by a device called a Light source and power meter (LSPM). This device will simply measure the absolute loss across the optical link. This then has to be compared with the design value of attenuation. If the tested value is less than the design value then the link can be seen to be acceptable.

Optical Time Domain Reflect meters (OTDR) can give a great deal of information about optical fibers, but for short haul multimode fiber they are an expensive overkill that gives results that need expert interpretation. An OTDR remains an essential tool for fault finding.

2010


Step 10: Final thoughts

The design of the cabling system in-step with the LAN aspirations of the end user?

For example, Cat5e is the minimum performance grade suitable for gigabit Ethernet.

Standard Cat5e cable may not have sufficient delay skew performance for RGB video systems however.

Cat 6 plus cabling will give a longer service life due to its higher performance, but at an initial higher cost.

Some optical fiber LANs, e.g. gigabit Ethernet cannot transmit over the full distance allowed in standards based optical structured cabling. These LAN limitations have to be taken into account. The next generation of 10 gigabit Ethernet will need a new generation of optical fiber to make it work.

The best way to ensure success in a structured cabling installation is to use properly trained people to design, implement and test the system. The RCDD qualification from BICSI is the only qualification which covers all aspects of structured cabling design and implementation.

The above information is offered as a summary of ISO 11801 and related standards. It is not a definitive design guide and does not replace study and implementation of the Standards themselves. The publisher accepts no responsibility for inaccuracies or omissions. To purchase the full Standards go to your national standards body, e.g. British Standards Institution, Netherlands Normalization Institute etc. or ISO.
