Can somebody tell me what LATA is?
Local Access and Transport Area. Essentially the geographical area defining local telephone service. Generally LATAs have "local" interests in common for example the Portland, Oregon LATA carves out a section of northwest Oregon and southwest Washington state. The eastern Massachusetts LATA includes most of eastern Massachusetts from Worcester to Boston/Newberryport to Cape Cod. Washington state is devided into three LATAs western Washington excluding the southwestern portion, Portland-Vancouver LATA and eastern Washington east of the Cascade range.
