TIA-606 labeling explained

ANSI/TIA-606-D (2021) is the standard for naming, labeling and recording a cabling system. Every space, rack, panel, port, cable and outlet gets an ID that says where it is, largest tier first.

• TIA-606 asks for one consistent scheme across the site and lets you pick the separators: . - / _
• If the owner or job spec has a scheme, use it everywhere.
• A port ID uses the floor its patch panel is on, even when the outlet it feeds is on another floor.

In DropMap you set your own TIA-606 scheme once, and it's applied to every port you map.

The four classes

The class sets how much you identify and record; each adds to the one below. Pick it for the whole system, not the part you touched.

Class 1

One building served by a single equipment room.

Class 2

One building, or one tenant, with several telecom spaces.

Class 3

A campus: several buildings and the outside plant between them.

Class 4

Several sites or campuses under one system.

Where labels go

• Both ends of every cable, near the termination, same ID at each end.
• The patch panel, its own ID plus one per port.
• The faceplate, with the identifier of the link behind each jack. It is the same ID as the panel port, so a caller can read it to you.
• Racks and telecom room doors.
• Bonding busbars in each telecom space.

The TIA-606 label generator lists a panel's IDs, and the patch panel port map lays out the panel.

In the field

• Zero-pad port numbers (07, not 7) so lists sort in order.
• Print labels rated for where they go. Handwriting fades and gets misread.
• Label the cable before you terminate it.
• Change the label and the record together.
