LAN (IEEE 802.3 10BaseT)
LAN (Local Area Network) is an Institute of Electrical and Electronic Engineers specification for a class of LANs using four-pair unshielded twisted pair (UTP) cable. See Local Area Network.

Local Access And Transport Area (LATA)
LATA is a geographic area (called an "exchange" or "exchange area" in the MFJ) within each BOC's franchised area that has been established by a BOC in accordance with the provisions of the MFJ for the purpose of defining the territory within which a BOC may offer its telecommunications services. In 1989, there were 198 LATAs, also referred to as market service areas (MSAs), in the United States.
Local Area Network (LAN)
LAN is a premises high-speed (typically in the range of 10 Mbps) data communications system wherein all segments of the transmission medium (typically coaxial cable, twisted pair or optical fiber) are contained within an office or campus environment.
Local Channel
In LEC tariffs, a local channel is the local loop that connects customer premises to serving LEC wire centers. In IXC tariffs, the network components (transmission, switching, other) used to connect customer premises to serving IXC POPs.
Loop Length
Typically, loop length is a complete electrical circuit; the pair of wires that winds its way from the central office to the telephone set or system at the customer's premises.
