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.
The busbar's material composition and cross-sectional size determine the maximum current it can safely carry. Busbars can have a cross-sectional area of as little as 10 square millimetres (0.016 sq in), but electrical substations may use metal tubes 50 millimetres (2.0 in) in diameter or more as busbars.
Provide the means for safe and effective grounding, bonding, and isolation connections for the metallic and dielectric components of the network. Functional performance requirements common to pole line hardware for utility poles made of wood, steel, concrete, or Fiber-Reinforced Composite (FRC) materials are contained in Telcordia GR-3174 ...
The 2 B channels can be aggregated by channel bonding providing a total data rate of 128 kbit/s. The BRI ISDN service is commonly installed for residential or small business service (ISDN PABX) in many countries. In contrast to the BRI, the Primary Rate Interface (PRI) configuration provides more B channels and operates at a higher bit rate.
Enclosure comparison with normal wiring & with busbar system. Electrical busbar systems [1] (sometimes simply referred to as busbar systems) are a modular approach to electrical wiring, where instead of a standard cable wiring to every single electrical device, the electrical devices are mounted onto an adapter which is directly fitted to a current carrying busbar.

With the 32-TC-PAM modulation scheme described in Annexes F and G, symmetric data rates of up to 5,696 kbit/s are permitted on one pair in the optional extended SHDSL mode. Up to four pairs of wires may be bonded using M-pair bonding to produce data rates as high as M5,696 kbit/s.
