The TC should not be a storage room. Most electronic equipment designed for telecommunications closets requires a limited temperature environment. Separately controlled heating and airconditioning for the TC are almost always required. Businesses rely heavily on their communications systems, so access to the TC must be limited to authorized personnel. The door should be lockable.
Most crossconnect devices can have colored labels or markers added for identification.
Sufficient space and hardware must be provided to handle the size and weight of the backbone cables, horizontal cables, patch cords and jumper cables. Provide a service loop at each termination for future adds, moves and changes. For 100 ohm UTP and 150 ohm STP, only use jumper cables, patch cords, and crossconnect devices that comply with the Category or extended requirements of the cabling system. Use of lower performance components will cause performance degradation, poor quality signals, and possible data loss. Thus it is important to maintain sufficient space for cooling and heating, servicing, and cable management.
