Which of the following is a recommendation and not a requirement for telecommunication enclosures?

The correct answer is that telecommunications enclosures (TE) should not be installed in furniture systems, as this is a recommendation rather than a strict requirement. The guidance around TE installation is designed to promote reliability, accessibility, and proper functioning of telecommunications systems.

Installing TEs in raised floors or using protective covers for TEs can be beneficial practices that enhance the physical protection and manageability of telecommunications infrastructure, but these are often based on project specifications and best practices rather than firm regulations.

Labeling all cables within TEs is typically considered a best practice to ensure proper management and troubleshooting. While this is strongly recommended to maintain organization and reduce errors, it is not classified as a requirement.

In contrast, the recommendation against installing TEs in furniture systems focuses on ensuring that devices are in accessible locations where they can be easily maintained and less prone to physical damage or interference. This consideration reflects the need for functionality and efficient management of telecommunications systems.
