Whether the telecommunications system is based on Shielded Twisted Pair (STP) or Unshielded Twisted Pair (UTP) cable, TIA-607-B requires that each and every metallic component making contact with a telecom cabling infrastructure be bonded, even if it is merely touching another metal component that is directly attached.
Two-wire and 4-wire voice-frequency trunks terminating at metallic terminal facilities and equipment which provides an interface between digital carrier equipment and the 4ESS switching network. The switching network contains the equipment which actually switches pulse code modulated data from one trunk or service circuit to another.
A typical volume of Bell System Practices from the 1970s. The Bell System Practices (BSPs) is a compilation of technical publications which describes the best methods of engineering, constructing, installing, and maintaining the telephone plant of the Bell System under direction of AT&T and Bell Telephone Laboratories.

In electric power distribution, a busbar (also bus bar) is a metallic strip or bar, typically housed inside switchgear, panel boards, and busway enclosures for local high current power distribution. They are also used to connect high voltage equipment at electrical switchyards, and low-voltage equipment in battery banks .
An electrical room is a technical room or space in a building dedicated to electrical equipment. Its size is usually proportional to the size of the building; large buildings may have a main electrical room and subsidiary electrical rooms. Electrical equipment may be for power distribution equipment, or for communications equipment. [1]
Equipment rooms house equipment and wiring consolidation points that serve the users inside the building or campus. Backbone cabling is the inter-building and intra-building cable connections in structured cabling between entrance facilities, equipment rooms and telecommunications closets. Backbone cabling consists of the transmission media ...
