21、ngs and campuses. Telecommunications pathways and spaces in multi-tenant buildings are challenged by the phased nature of their use. After the building is constructed and the first group of tenants moves in, the tenants telecommunications needs may immediately cause modifications to the building. Ov

22、er a span of years, as tenants cycle through the building, evolving tenant needs will oblige the owner/agent of the building to adapt its installations to these demands. Multi-tenant commercial office and residential buildings have life cycles that mirror that of single-tenant buildings. Many buildi

23、ngs are over 100 years old. Over time, these older buildings have become severely challenged to support escalating demands on their pathways and spaces as a result of tenants ever-increasing needs for telecommunications connectivity. Figure A.1 illustrates a representative model for the various func

24、tional elements that comprise multi-tenant pathways and spaces for a building. This is not intended to be an all-inclusive representation. It depicts the relationship between the elements and how they are configured to create a total system. Table A.1 provides a summary of the telecommunications spa

25、ces. Elements of multi-tenant spaces include, but are not limited to, entrance room, access provider space, service provider space, common equipment room and common telecommunications room. 18010 Amend. 1 ISO/IEC:2005(E) 9 Figure A.1 Example of pathways and spaces components used to service a multi-

28、 facilities A.2.1 Entrance location considerations Consideration should be given to facility, occupants and users telecommunications wireline and wireless connectivity needs. If access to both wireline and wireless services is required, then the entrance facilities may require adjustment in size, qu

29、antity and location. Mechanical fixtures (e.g., piping, ductwork, pneumatic tubing) not related to the support of the entrance facility should not be installed in, pass through, or enter the telecommunications entrance facility. A.2.2 Telecommunications service entrance pathway Telecommunications se

30、rvice entrance pathways shall be specified to support the initial and forecasted telecommunications needs including the total building area served and wireline and wireless tenant connectivity requirements. The forecasted telecommunications needs shall be agreed upon between the building owner and t

31、he designer. Accommodations should be made for multiple service entrance points to support multiple access providers. A.2.3 Access Access to the entrance room shall be controlled by the primary or secondary responsible organization (see table 1). Signage, if used, should be developed within the secu

32、rity plan of the building. A.2.4 Wireless A.2.4.1 Line of sight Wireless transmission/reception device placement is critical to its performance. Obstructions to a wireless transmission/reception device function can take many forms including radio frequencies, electrical and physical objects. Obstruc

33、tions may be on the same platform, on an adjoining building or be located some distance away. Wireless transmission/reception devices shall be in line of sight with its target system if required by the employed technology. Certain systems will not function properly if the wireless transmission/recep

34、tion devices line of sight is obstructed. A.2.4.2 Cable pathways Cable pathways from tower-mounted wireless transmission/reception devices should be consolidated where possible on the tower and remain consolidated along their route to the access provider space. The most direct route between the wire

35、less transmission/reception device and the entrance facility should be followed. To protect cables from environmental damage and isolate cables from pedestrian traffic, they should be placed inside conduit or in cable tray, or be otherwise secured from physical damage. 18010 Amend. 1 ISO/IEC:2005(E)

36、 11 A.2.4.3 Location Depending upon function and site conditions, wireless service transmission/reception spaces may be located at the buildings upper rooftop, outside walls or on lower roof setbacks. Wireless service transmission/reception points may also be located inside the building. Wherever po

37、ssible, wall-mounted wireless transmission/reception device support structures should be mounted at a minimum of 2 m above surfaces where foot traffic may occur. A.2.4.4 Support structures A.2.4.4.1 General A structural analysis shall be carried out by a relevant specialist to aid in the design and

38、placement of wireless transmission/reception device support structures. A.2.4.4.2 Towers Where the location or height of the building makes it a desirable wireless transmission/ reception device site, consideration should be given to installation of a tower on top of the building. Towers are desirab

39、le because they allow efficient use of limited rooftop space, and offer significant flexibility regarding space planning. Multiple access providers and other users may share space on a single tower. A.2.4.4.3 Non-penetrating wireless transmission/reception device mounts Wireless transmission/recepti

40、on devices that are of limited weight and size may be installed on mounts, which are not fastened to the building structural members. These types of wireless transmission/reception device mounts are often referred to as sled mounts, ballast mounts or non-penetrating wireless transmission/reception d

41、evice mounts. These mounts remain secured to the rooftop by their own weight plus addition of dead weights to keep the wireless transmission/reception device in place. The amount of weight (ballast) required is calculated with consideration given to loading created by wind and ice build-up on the wi

42、reless transmission/reception device and supporting system. In some cases, these mounts are tethered for increased stability. Local regulations may provide specific requirements that have to be observed. The building owner has to be consulted for permission to add load to the roof. A.2.4.4.4 Penetra

43、ting wireless transmission/reception device mounts Wireless transmission/reception device mounting systems that penetrate either the rooftop or walls of a building are commonly employed. The primary considerations with such systems are the loading that the system places on the structure and waterpro

44、ofing of any penetration points. A.2.4.5 Design considerations Electrical service shall be sized to support functions that include, but are not limited to antenna lighting, de-icing and motor-operated functions where required. Where mandated by regulatory code, automatic switchover to standby power

45、shall be provided. Sizing of the electrical service shall be carried out by a relevant specialist. A.3 Access provider spaces and service provider spaces A.3.1 General Access to the access provider spaces and service provider spaces shall be controlled by the primary or secondary responsible organiz

46、ation (see table 1). Common approaches include lockable cabinets and caged spaces. 12 18010 Amend. 1 ISO/IEC:2005(E) A.3.2 Location A.3.2.1 General Access provider spaces and service provider spaces should be in close proximity to the common equipment room (CER). The access provider and service prov

47、ider spaces should be selected so that the area may be expanded. Access provider spaces and service provider spaces shall be configured so that each can be accessed through common-use corridors. Wireless access provider spaces should be located as close as practical to the wireless transmission/rece

48、ption devices to which they are connected. A.3.2.2 Electromagnetic interference Access provider and service provider spaces shall be located away from sources of electromagnetic interference. Examples of such noise sources include electrical power supply transformers, motors and generators, x-ray eq

49、uipment, radio or radar transmitter and induction sealing devices. A.3.3 Pathways Adequate cable pathway should be provided from access provider spaces to the CER, from service provider spaces to the CER, and from access provider spaces to service provider spaces. A.3.4 Design A.3.4.1 Architectural considerations A.3.4.1.1 Partitions Where access providers and service providers share space, individual spaces should be segregated by means of partitions. Partit
