Abandoned cables are those no longer in use and not tagged for future use. This is generally assumed to mean that all early coax cables used for LANs or mainframe computer systems, all unused Cat 3 and Cat 5, and any other cables replaced by newer-generation cables should be removed. All those cables are contributors to fire and smoke and are considered hazardous. Note, however, that this requirement applies only to accessible cables. Although inspectors are supposed to include abandoned cables in inspections of new installations, few data-voice installations are actually inspected, and inspectors may not know how to recognize abandoned cables.

By consolidating cabling to the zone drop, the cost of installation and the cost of moves and changes can be cut.
