What color plywood is required to be used at all telephone terminal spaces (TTS)?

In telephone terminal spaces (TTS), the standard color used for plywood is gray. This is in line with established telecommunications industry standards that designate specific colors for various components and materials to ensure consistency and ease of identification. The use of gray plywood helps technicians and installers quickly locate telephone terminal spaces within a building, promoting efficiency during installation, maintenance, and troubleshooting tasks.

Choosing gray plywood also aligns with practices to differentiate it from other wiring and equipment spaces that may use different colors, enhancing clarity and reducing the risk of errors. While other colors like white, blue, and brown may be designated for various other uses in construction or telecommunications applications, gray is specifically recognized for TTS usage.
