coupled bonding conductor
A conductor that is connected between a PBX single-point ground
(CBC)
and the protector ground terminal. It is run adjacent to protected
pairs in an associated cable. The mutual coupling between the
bonding conductor and the pairs reduces electrical potential
differences in terminating equipment.
This conductor can be constructed in one of the following manners:
cross-connect block
cross-connect field
customer participation
data-link transformer
When pairs are run in a shielded cable, the cable shield can be
used as the CBC.
With inside wiring cable, 10 AWG wire that is tie-wrapped to the
cable can be used as the coupled bonding conductor.
If the use of 10 AWG wire is impractical, six dedicated, good
spare pairs within the cable may be used as the coupled bonding
conductor. The six spare pairs must be twisted and soldered to
prevent their use for other purposes.
A flame-retardant plastic block containing metal wiring terminals
(quick clips) used to establish cross-connections between cables.
An arrangement of cross-connect blocks used for the termination and
cross-connection of groups of cables.
The set up and removal of cross-connections at the main and
intermediated distribution fields (MDFs and IDFs) by the customer.
An isolation transformer, used for secondary electrical protection, that
protects against residual voltages and sneak currents.
