Telecommunications Room

Telecommunications Rooms (TR) are generally considered to be floor serving facilities for horizontal cable distribution. They may also be used for intermediate and main cross-connects.

Some specifications related to the telecommunications room:

(TR's) shall be designed and equipped in accordance with TIA-569-B.
Cable stress from tight bends, cable ties, staples, and tension should be avoided by well-designed cable management.
Only standards-compliant connecting hardware shall be used.
Application-specific electrical components shall not be installed as part of the horizontal cabling.
Horizontal cable terminations shall not be used to administer cabling system changes. Instead, jumpers patch cords, or equipment cords are required for re-configuring cabling connections.
The two types of schemes used to connect cabling subsystems to each other and to equipment are known as interconnections and cross-connections.

Note:
A "cross-connect" (a.k.a. distributor) is a facility, whereas a "cross-connection" is a connection scheme. Cross-connections are typically used to provide a means of configuring individual port connections between the cabling and equipment with multiport outputs (i.e., 25-pair connectors). Interconnections may be used with equipment that has individual output ports. A cross-connect facility (a.k.a. distributor) may house interconnections, cross-connections, or both.
