ERs are used to:
• Accommodate portions of common control equipment such as voice, intrusion detection, data,
video, fire alarm, energy management, etc.
• Provide work space for service employees.
• Provide for termination and cross-connection of backbone and horizontal cables.
Telecommunications Room
The Telecommunications Room (TR) houses the connection point between the building backbone and
horizontal distribution pathways.
TRs are used to:
• Maintain a controlled environment for the telecommunications equipment, splice closures,
and connecting hardware.
• Provide a point of termination for horizontal and backbone cables on compatible connecting
hardware.
Backbone Pathways and Cabling
Backbone Pathways and Cabling, as the name suggests, carry the signals between the entrance
facilities, equipment rooms and telecommunications rooms. Pathways are the vertical and
horizontal route of the cable, including support structures. The backbone cabling system enables
interconnections between EFs, TRs, ERs, and main terminal space. The distance between the
terminations in the entrance facility and the MC should be documented and made available to the
service provider.
The backbone also extends between buildings in a campus environment. It includes backbone cables,
cross-connects, mechanical terminations, and patch cords or jumpers used for backbone-to-backbone
cross-connections.
