TIA/EIA-606-A Description Summary

The TIA/EIA-606-A standard establishes guidelines for owners, end users, manufacturers, consultants,

contractors, designers, installers and facilities administrators involved in the administration of the

telecommunications infrastructure.

Four classes of administration are specified in the standard, to accommodate diverse degrees of

complexity present in the telecommunications infrastructure. The specifications for each class include

requirements for identifiers, records, and labeling.

Class 1

addresses the administration needs of a premise that is served by a single

Telecommunications Space (TS) containing its telecommunications equipment.

Required in class 1 administration are identifiers for the TS, any Telecommunications Main Grounding

Busbar, and all elements of the horizontal links.

For a copper horizontal link, the elements include:

• the connecting hardware (e.g., patch panel port or the section of a punchdown block terminating a

four pair horizontal cable)

• a four pair horizontal cable

• a telecommunications outlet/connector terminating a four pair horizontal cable in the work area

If a Consolidation Point (CP) is present:

• the segment of four pair horizontal cable extending from the TS to the CP connecting hardware

• the CP connecting hardware or section of a punchdown block terminating a 4-pair horizontal cable

• the segment of 4-pair horizontal cable extending from the CP connecting hardware to the

outlet /connector of a Multi-User Telecommunications Outlet Assembly (MUTOA) or to the work area outlet

If a MUTOA is present:

• a telecommunications outlet/connector in the MUTOA

For an optical fiber horizontal link, the elements include:

• a pair of optical fiber terminations on a patch panel in the TS

• a pair of optical fibers in a cable

• a pair of optical fiber terminations in the work area

• a telecommunications outlet/connector terminating a pair of optical fibers in the work area

If a Consolidation Point (CP) is present:

• the segment of optical fiber cable extending from the TS to the CP connecting hardware

• the CP connecting hardware or section terminating a pair of optical fibers

• the segment of optical fiber cable extending from the CP connecting hardware to the outlet /connector

of a MUTOA or to the work area outlet

Class 2

administration provides for telecommunications infrastructure administration

needs of a single building or tenant that is served by a single or multiple TSs within

a single building. Class 2 administration includes all elements of class 1 administration, plus

identifiers for backbone cabling, multiple-element grounding, and bonding systems, and firestopping.

Class 3

administration addresses the needs of a campus, including its buildings and

outside plant elements. Class 3 administration includes all elements of class 2

administration, plus identifiers for buildings and inter-building cabling. Administration of pathways and

spaces, and of outside plant elements is recommended.

Class 4

administration addresses the needs of a multi-site system. Class 4 administration

includes all elements of class 3 administration, plus an identifier for each site and

optional identifiers for wide area network connections.
