<td><font size="2" face="Arial">Telecommunications rooms provide many
different functions for the cabling system and are often treated as a
distinct sub-system within the hierarchical cabling system.</font>
<p><font size="2" face="Arial">The primary function of a
telecommunications room is the termination of horizontal and backbone
cables to compatible connecting hardware. The cross-connection of
horizontal and backbone cable terminations using jumpers or patch cords
allows flexible connectivity when extending various services to
telecommunications outlet/connectors. Connecting hardware, jumpers, and
patch cords used for this purpose are collectively referred to as
"horizontal cross-connections".</font></p>
<p><font size="2" face="Arial">A telecommunications room may also contain
the intermediate cross-connect or the main cross-connect for different
portions of the backbone cabling system. Sometimes backbone-to-backbone
cross-connections in the telecommunications room are used to tie different
telecommunications rooms together in a ring, bus, or tree configuration.</font></p>
<p><font size="2" face="Arial">A telecommunications room also provides a
controlled environment to house telecommunications equipment, connecting
hardware, and splice closures serving a portion of the building. The
telecommunications room provides for the administration and routing of the
equipment cables/cords from the horizontal cross-connect to the
telecommunications equipment.</font></p>

associated protection apparatus may be located in the
telecommunications room. </font></li>

located on the same floor as the work areas served.</font></li>
