Situation:
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.
The ADC Alternative—micro-DLC Solutions
ADC's PG-Flex
Plus
micro-DLC system meets the challenge by providing quick and economical
distribution relief from central offices (CO) or DLC locations.
The PG-Flex
Plus
micro-DLC is a 2 component system consisting of a Central Office Terminal (COT) and
remote terminals (RTs). The COT supports an integrated (D4/TR-008) interface to a class 5 switch and
is temperature hardened for deployment from Central Offices (COs), vaults (CEVs) or DLC locations.
Line powered and environmentally hardened RTs deliver 6-channels over 1 copper pair or
24-channels over 2 copper pairs.
