Introduction

The new labeling standard as presented in the EIA/TIA-606-A addresses the need for an independent and scalable labeling standard in the administration of telecommunications cabling infrastructure. In order to standardize and administer the totality of infrastructure here at the University of Florida it is necessary to have a complete standard for labeling so that technicians do not need to reinterpret the labeling as they move from one building to the next. Contractors need a concrete labeling scheme furnished to them so that they can make their products as useful as possible to us.

According to the 606-A standard, what we are presently concerned with would be considered a class 3 labeling standard. We have multiple buildings and outside pathways that must be documented. All identifiers are independent and scalable. All labels read from the general to the specific from left to right.

It should be noted, that by horizontal cabling we are referring to any piece of the cable plant that feeds directly from a Telecommunications Room out to a users outlet or work area. This includes cable that feeds out to a consolidation point in the work area.

Particulars of the Standard

Every component of the telecommunications infrastructure is to be labeled in an independent manner. The most critical point of a standard built around the 606A is that horizontal labeling is based on a point of origination.Each horizontal cable is labeled on both ends with an identifier that locates it's termination point in the appropriate Telecommmunications Room.

LabelTarget Example Explanation
Building 0115 University of Florida official building number
Telecommunications Room 1A 1 - first floor, A - Telco room A
Port Number 15 Designates port number 15
Communication Panel A Designates Panel A in a Telco Rack
Fiber Panel FPL1 Designates the first Fiber Panel in a Telecommunications Room

Reading a Name

These individual identifiers can be combined to create an overall and accurate picture of a cabling plant. Each individual piece of hardware will require a minimum amount of labeling that can be combined in the documentation to specify a particular piece of hardware. A name is constructed combining the pertinant labels from the appropriate infrastructure elements. For purposes of saving cable tests, the full name should include building number, Telco Room number, rack number, patch panel letter and port number.

reading name

For non-UTP horizontal terminations, more description is necessary and the format below will be followed.

Examples

Horizontal examples:

0047-1A-1A45

UTP cable originates in Building 047, Telecommunications Room 1A.
UTP cable originates in Rack #1, Patch Panel A, Port 45.

0047-3B-WA37

UTP cable originates in Building 047, Telecommunications Room 3B
UTP cable originates in wall mounted Patch Panel A, Port 37.

0047-3B-3A37

UTP cable originates in Building 047, Telecommunications Room 3B
UTP cable originates in the Rack #3, Patch Panel A,Port 37

Non-UTP in horizontal installation examples*

0047-1A-2FPL1.1

Fiber Panel is located in Building 47, Telecommunications Room 1A
This is the first fiber port in Rack #2, Fiber Panel #1

0155-1A-WXPL1.1

Coaxial Panel is located in Building 155, Telecommunications Room 1A
This is the first coaxial port in wall mounted coaxial panel 1, Port #1

The Standard in Implementation

Having a new labeling standard does not help anyone without a plan to implement that scheme. Implementing a new labeling scheme for as large a body is this is going to be a long multi-step process. The first and most important step of which is to make sure that any new installations are labeled in accordance with the new scheme.

New installations should follow the scheme as laid out above.

How to Label:

Buildings

For purposes of identifying buildings see the appropriate section of the Backbone Cable Labeling Standard.

A Telecommunications Room

For purposes of identifying Telecommunications Rooms see the appropriate section of the Backbone Cable Labeling Standard.

A Telecommunications Rack

For purposes of identifying Telecommunications Racks see the appropriate section of the Backbone Cable Labeling Standard.

Patch Panels and Termination Blocks

Data Use

  1. Termination Blocks or Patch Panels shall be labeled with an alphabetical identifier. This identifier for a rack mounted panel should begin with with the letter A and continue on through the alphabet as more patch panels are added to that particular rack or wall space.
  2. Labeling of panels or punch blocks with letters will begin again with A as more blocks are added in a different termination zone. For example, labeling of panels should begin again with the letter A for each new rack and the labeling of panels on the wall should begin with A.
  3. Individual ports on the panel should be numbered in ascending order. If not printed on the panel by the manufacturer, the installer is responsible for making sure that each port is labeled with its own number.

Conduit and Innerducting

For purposes of identifying innerduct and conduit see the appropriate section of the Backbone Cable Labeling Standard.

Horizontal Cable and Outlet Boxes (See figure 1)

  1. Each end of the horizontal cable should be labeled on the outside jacket of the cable within 12 inches of the termination points.Horizontal cables need no building identifier placed on the cable itself.This label will follow the conventions outlined above with a typical label being 1A-1A03.
  2. Outlet boxes shall be labeled on the appropriate area with the name of the cable without the building designator. For example, the outlet connection for 0047-1A-1B05, should be labeled 1A-1B05.

Conclusion

This document covers the most common labeling needs for the installation of horizontal cable and conduits across the University of Florida. There are a number of more specific situations covered in the EIA/TIA 606A labeling standard. If you have any questions concerning these standards and their interpretation in reference to the University of Florida contact Network Services.
