6 Selection of the telecommunications bonding network approach
6.1 Assessment of the impact of the telecommunications bonding network on the
interconnection of telecommunications equipment
Replace paragraphs 2, 3 and 4 with the following:
The mesh bonding network of Clause 11 provides the most effective bonding at high
frequencies and can provide effective bonding at low frequencies. It is intended to support the
most demanding requirements of both cabling media and the applications supported over
those media (see Table 1). In addition, it provides the most flexibility in relation to the types
and locations of telecommunications equipment that may be installed (subject to the
transmission performance limits of the applications when using the selected
telecommunications cabling).
The installation of such a telecommunications bonding network is most easily implemented
during new construction or refurbishment of a building or s
