SIGNAMAX CABLINGSYSTEM
Signamax Cabling System
• The Signamax Cabling System Design Principles and Installation Practices are based on the requirements and recommendations of the international and national standards for telecommunications cabling within a commercial building and between buildings in a campus environment
• These rules specify cabling topology, transmission media, cabling distances, and telecommunications outlet configurations
Signamax Cabling System
• Rules given by the Manual are intended to implement a telecommunications cabling designed to support a wide range of different commercial building sites and applications (e.g., voice, data, text, video, and image)
• Typically, this range includes sites with a geographical extent from 3,000 m (about 10,000 ft), up to 1,000,000 m2 (about 10,000,000 ft2) of office space, and with a population of up to 50,000 individual users

Functional elements
• Generic telecommunications cabling system consists of the following functional elements:– Main Cross-connect (MC)– Level I Backbone subsystem cable– Intermediate Cross-connect (IC)– Level II Backbone subsystem cable– Horizontal Cross-connect (HC)– Horizontal subsystem cable– Consolidation Point (CP)– Multiuser Telecommunications Outlet Assembly (MuTOA
or MuTO)– Telecommunications Outlet (TO)
• Groups of these functional elements are connected together to form cabling subsystems

Subsystems
• Signamax Cabling System schemes consist of three cabling subsystems:
– Level I Backbone
– Level II Backbone
– Horizontal cabling
• The cabling subsystems are connected together to create a generic cabling structure as shown on the next slide.The cross-connects provide the means to configure the cabling to support different topologies like bus, star and ring

Channel & Permanent Link
• The Channel is the transmission path between active equipment and the terminal equipment.For the purposes of testing, the Channel does not include the mated connection at the IT equipment.

Channel & Permanent Link
• The Permanent Link is the transmission path between the mated connectors located at the ends of the installed cable in a cabling subsystem.The Permanent Link contains the mated connections located at the ends of the installed cabling

Dimensioning & configuring
• The number and type of subsystems that are part of a generic cabling implementation depends on the geography and size of the campus or building, as well as on the user strategy. Generally there would be
– one Main Cross-connect per campus
– one Intermediate Cross-connect per building
– one Horizontal Cross-connect per floor
• If the premises have only a single building, which is small enough to be served by a single Horizontal Cross-connect, a level I Backbone cabling subsystem is not required
Dimensioning & configuring
• Cross-connects should be located such that the resulting cable lengths comply with the Channel performance requirements set forth in the
– “HORIZONTAL SUBSYSTEM”
and
– “BACKBONE SUBSYSTEM” sections
• The maximum Channel lengths shown on the next slide should be observed
Dimensioning & configuring
• Maximum allowable Channel lengths in the cabling subsystems:
• The distances given are for the total backbone Channel length, including backbone cable, patch cords or jumpers, and equipment cable
Channel TypeDistance,
m (ft)
Horizontal subsystem (HC – TO) 100 (328)
Level II Backbone subsystem (IC – HC) 300 (984)
Level I + II Backbone subsystem (MC – HC)
2,000 (6,562)5,000 (16,404)
Dimensioning & configuring
• Not all applications are supported over the maximum lengths shown in the previous table using a single cable type
• The maximum supportable distances are application and media dependent
• To determine the maximum acceptable Channel length refer to standards for specific telecommunications applications
• Installer companies are advised to consult the specific standards associated with the planned service, or equipment manufacturers to determine the suitability of the cabling described herein for specific applications
Dimensioning & configuring
• There should be at least one Horizontal Cross-connect for every 1,000 m2 (10,000 ft2) of floor space reserved for offices
• If a floor area is over 1,000 m2 (10,000 ft2), additional Horizontal Cross-connectsmay be required to providemore effective serviceto the Work Area

• A minimum of one Horizontal Cross-connect should be provided for every floor. If a floor contains few people (e.g. a lobby), this floor may be served from the Horizontal Cross-connect located on an adjacent floor.If a floor is sparselypopulated (e.g. a lobby),it is permissible to servethis floor from theHorizontal Cross-connectslocated on an adjacent floor

• In some conditions, for example for reasons of security or reliability, redundancy may be built into a cabling design.This might form the basis for the design of generic cabling for a building, providing some protection against such hazards as fire damage or the failure of the public network feeder cable
