8.8 TELECOMMUNICATIONS ROOMS (TR)

The Telecommunications Rooms (TRs) are defined as the interface between the backbone cabling system and the horizontal cabling
system. The TRs, located on each floor, provide space for backbone and horizontal cable terminations, patching and cross-connect
equipment, LAN/WLAN electronics and interfaces between the cabling backbone, transport electronics and end user devices.
The placement of TRs is ultimately dictated by the criteria established under the TIA 568C standard which limits horizontal
communications cabling to a distance limitation of 295 feet, installed and terminated. WSP recommends that design considerations
shall limit this figure to a limit of 250 linear feet to account for real-world installation conditions and vertical and horizontal bends.
TRs shall stack and share same vertical stack of closets with the electrical rooms. A TR shall be dedicated to serve the floor it is on,
with the exception being where it is also housing an amplifier unit for a DAS repeater system.

This will be the means of transporting base building backbone and tenant carrier services backbone cabling throughout the
building.
The TR’s will be arranged to accommodate the following systems and equipment:

• Termination and patching facilities for horizontal cabling
• Termination and patching facilities for voice, data and video backbone cabling
• Hardware and racking for LAN cabling switches, VoIP switches, video cabling hubs, converters, and other device sharing
equipment
• Wireless LAN networking equipment
• Building Management Systems

• Security Systems
• CATV equipment
• Vertical riser pathways
Power outlets for any transmission and terminal equipment located within the TR shall be fed from an electrical panel dedicated to
these loads, ideally located within each TR.
Panels serving the TR’s shall be on the building UPS/emergency power distribution system.

Dedicated cooling, electrical and fire suppression provisions are recommended for the TRs, to allow the network and associated
electronics to operate efficiently and reliably over the life cycle of the building.
The installation shall be in accordance with TIA 569A. The following are recommended guidelines for the TR’s:
