Local Exchange Carriers (LECs) need to provide new services in areas where there are shortages of
copper pairs in the distribution plant (F2) beyond existing Digital Loop Carrier (DLC) systems. In
today's environment of reduced capital budgets (CAPEX), adding network capacity quickly and
economically is most challenging where (1) the estimated demand for service does not justify a
major cable, crossbox, or DLC installation. Or (2) an immediate service order response is needed.
