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


• 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

Cabling Structure

• Generic telecommunications cabling system structure includes the following subsystems and additional elements:

– Horizontal subsystem

– Backbone subsystem

– Work Area

– Telecommunications Room

– Equipment Room

– Entrance Facility

– Administration

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 Signamax Cabling System consist of Channels and Permanent Links.The transmission performance of structured cabling between specific interfaces is detailed in terms of the Channel and the Permanent Link

Terminal Equipment

HC TO


• 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.

HC TO


• 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

HC TO

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


• 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


• 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)

Level II Backbone subsystem (IC – HC) 300 (984)

Level I + II Backbone subsystem (MC – HC)

2,000 (6,562)5,000 (16,404)


• 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


• 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
