Horizontal Cross Connect
A wiring closet where the horizontal cabling connects to a patch panel, which is connected by
backbone cabling to the main distribution facility.
Identifiers
A unique identifier associated with each element of the infrastructure which serves as the key
to finding the recorded information in the cable management system.
IP Address
An Internet Protocol (IP) address is a numerical identification (logical address) that is assigned
to devices participating in a computer network using the Internet Protocol for communication
between its nodes.
Labeling
The size, color and contrast of all labels should be selected to ensure that the identifiers are
easiliy read. Labels should be visible during the installation and normal maintenance of the
infrastructure. Labels should be resistant to the environmental conditions at the point of
installation (e.g., moisture, heat or ultraviolet light) and should have design life equal to or
greater than the labeled component. To maximize legibility, all labels should be printed or
generated by a mechanical device and not be hand written.
Linkages
Linkages support the retrieval of information about the telecommunications infrastructure from
administration records. When administration is performed with cable management software,
linkages should be provided between each appearance of an infrastructure identifier in a
record or any record for which that identifier is the primary indexing identifier. Linkages to
additional records in which the identifier appears are also desireable.
LU
Logical Unit.
MAC Address
Medial Access Control address (MAC address). Also known as Ethernet Hardware Address
(EHA), hardware address, adapter address or physical address. A MAC address is a quasi-
unique identifier assigned to most network adapters or network interface cards (NICs) by the
manufacturer for identification.
