This section provides general specifications and design guidelines for the design and installation of cable television systems the University Department of Housing oversees and operates. While  service may be provided by outside commercial providers,  all systems installed in UNH buildings shall be in conformance to these Guidelines will be considered for later take-over by UNH Housing.  B. Any outlet intended to be accessible for viewing primarily by the public not affiliated with UNH may not be served by the Department of Housing cable system, and must be served by a completely separate commercial service and in-building infrastructure.  1.2 RELATED REQUIREMENTS FOUND ELSEWHERE   A. See Chapter 5, Division 01, Section 017700.1.1.B.1.i Closeout Procedures - Project Record Documents for equipment list requirements for all equipment provided in this section. B. Related Sections 1. Refer to electrical Section 26 0100 for Basic Electrical Requirements  2. Refer to electrical Section 26 0530 for Conduits. 3. Refer to electrical Section 26 0536 for Boxes and Fittings. 1.3         CODES AND STANDARDS   A. all work shall comply with applicable NFPA 70 (NEC)  1.4 NOTES TO DESIGNERS: A. General: 1. The Contractor is responsible for providing and installing all conduits, pathways, and drop and non-drop Cable TV (CATV) cables. The Contractor is also responsible for preparing a secure location for the Node or IDP closet as designated by the Designer for the Cable TV electronics. At the Contractor’s option, UNH Telecommunications can be engaged to pull cables for the Contractor. Conduits and pathways are provided and installed by the Electrical Contractor. Final terminations, start-up, testing, and commissioning of drop cables shall be by UNH Housing or its designated agent.  2. Generally a drop is defined as a cable where one end of the cable, the initiation end (drop initiation) is located at the Node or IDP closet. The other end of the cable, the termination end (drop termination) is located where the TV or monitor is expected to be located. UNIVERSITY of  NEW HAMPSHIRE    PLANNING, DESIGN AND CONSTRUCTION GUIDELINES February 26, 2016 CHAPTER 5 – TECHNICAL CONSTRUCTION AND RENOVATION STANDARDS SECURITY CARD ACCESS 28 1000 - 2 3. UNH Housing generally uses a Passive Optical Network Design to provide Cable TV. Consult with UNH Housing on project system design.  All Node, IDP, and pathway plans and locations shall be offered for review and approval by UNH Housing. B. Exterior and site Infrastructure 1. If no CATV service currently exists within the building, or at the site for a new building, or if service is to be provided by an outside commercial provider consult with UNH Housing and IT-Network operations (aka. UNH Telcom) as to the proper location where service shall originate from and provide a 4” diameter conduit from that point to the Node location. Refer to UNH Telcom standards for buried conduit requirements.  2. Ideally all infrastructure will be in underground pathways. However, when necessary aerial pathways can be used. All pathway must be approved by UNH Telecom, Campus Planning, and UNH Housing.   C. Electronics Locations: 1. Node Locations  a. Designer shall designate and design for a Node such that the location is within 300’ of the furthest drop termination served by the Node. See C-2-a when this is not possible. b. Nodes shall be located in secure room dedicated for the purpose, or may be located in a Telcom room as long as the room is large enough to accommodate the CATV floor area and equipment needs in addition to the minimum floor area needs required by Telcom. c. The minimum floor area for a Node and equipment is a clear space of 48” wide by 36” in depth. One of the 48” sides shall run adjacent to a clear unobstructed section of wall that is at least 8’ in height, and covered by a single sheet of ¾” marine grade plywood painted white or grey. d. Provide a 110 volt quad outlet with at least 5 amps of spare capacity at the upper left or right hand corner of the board.    2. Intermediate Distribution Points (IDP)  a. When it is not possible to locate the Node within 300’ of the furthest end user terminations, it is acceptable to use Intermediate Distribution Points (IDP’s) to run what is typically a ½” to ¾” diameter hard line coax between the two points as long as the distance between the Node and the IDP does not exceed 750’.  b. IDP locations shall be centrally located to the drop locations they interface with and stacked vertically in the building as is best possible. c. Drop cable lengths shall not exceed 300’ between the IDP and the drop termination. d. Contractor shall design and provide for a minimum 2-1/2” diameter conduit pathway between the Node location and any one IDP. When serving 2 or 3 IDP’s in a continuous circuit from the Node, design and provide for a minimum 4” diameter conduit pathway. Pathway may contain no 90 degree bends and no more than four 45 degree bends. UNIVERSITY of  NEW HAMPSHIRE    PLANNING, DESIGN AND CONSTRUCTION GUIDELINES February 26, 2016 CHAPTER 5 – TECHNICAL CONSTRUCTION AND RENOVATION STANDARDS SECURITY CARD ACCESS 28 1000 - 3 e. IDP’s shall be located in secure room dedicated for the purpose, or may be located in a Telcom room as long as the room is large enough to accommodate CATV floor area needs in addition to minimum floor area needs required by Telcom. f. The minimum floor area for an IDP is a clear space of 48” wide by 36” in depth. One of the 48” sides shall run adjacent to a clear unobstructed section of wall that is at least 8’ in height, and covered by a single sheet of ¾” marine grade plywood painted white or grey. D. Interior Drop Locations: Design Requirements  1. Residential Facilities  a. All designed 2 bed student and/or RA rooms shall have one CATV outlet installed. b. All designed 3 or 4 bed student rooms shall have one CATV outlet installed unless Housing requires a second drop to allow for variable TV placement in larger resident rooms. This will be decided on a case by case basis. c. Where a group of spaces are designed as an apartment, each bedroom shall have one CATV outlet installed, as well as one CATV outlet for the living room. d. All lounges shall have a minimum of one CATV outlet installed. e. All residence hall offices shall have one CATV outlet installed.  2. Non-residential Facilities  a. CATV is not required in non-residential buildings. CATV is provided on an as-needed/requested basis. b. Where provided for new buildings, additions, and general renovations, drop locations, locations of Node and IDP’s (if applicable), shall be shown on the plans. All interconnecting pathways between these locations shall be shown/noted on the electrical plans for installation by the electrical contractor, or references made on the electrical plans to other plans where these locations are shown and that the pathways are the responsibility of the electrical contractor.
