In U.S. telecommunications,Local access and transport area (LATA) refers to a geographical area in the U.S. which is allocated to telephone companies. The telephone companies, legally termed as local exchange carriers (LECs) provide telecommunication services, within the allotted areas.
A LATA may be within the same U.S. state or may span across more than one state, as laid down in Telecommunications Act of 1996.
Two types of connections are possible.
IntraLATA − It is a connection between two LECs within the LATA.
InterLATA − It is a connection providing long-distance service between LECs in different LATAs.
