and bonding systems are an integral part of the screened twisted-pair (ScTP)
telecommunications cabling system. In addition to helping protect
personnel and equipment from hazardous voltages, a proper grounding and
bonding system may reduce EMI to and from the telecommunications cabling
system. Improper grounding and bonding can produce induced voltages and
those voltages can disrupt other telecommunications circuits. </font>

applicable authorities or codes. </font></p>

grounding/bonding shall conform to ANSI/TIA/EIA-607
requirements. </font></li>
<li><font face="Arial" size="2">The shield of ScTP cables shall be
bonded to the telecommunication grounding busbar (TGB) in the

cabling, the voltage measured between the shield and the ground wire
of the electrical outlet used to supply power to the workstation shall
not exceed 1.0 V RMS. The cause of any higher voltage should be
removed before using the cabling.</font></li>

usually accomplished through the equipment power connection. Shield
connections at the work area are accomplished through an ScTP patch
