Automated database documentation systems can also be very useful. Some cable
administration software has a graphical interface that lets you point to items in your
cable plant and see the pertinent information that is recorded. A cable administra-
tion system can really be operated apart from the network management system
(NMS) for your LAN.
NMSs tend to concentrate on network node and hub management and control
and are not concerned with what cable duct a particular pair might be located in.
In addition, the cable administration software can cover telecommunications cable
uses that are far beyond the LAN.
