TAILIEUCHUNG - Reviving Exhausted Structure

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. | PG-FlexPlus Reviving Exhausted Structure application note 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-FlexPlus micro-DLC system meets the challenge by providing quick and economical distribution relief from central offices CO or DLC locations. The PG-FlexPlus 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. Figure 1 PG-FlexPlus micro-DLC Relief From the DLC Cabinet The PG-FlexPlus COT can be placed in a DLC cabinet allowing line powered RTs to be placed deep into the outside plant OSP . Reviving Exhausted Structure Relief for the Crowded Cabinet If the DLC cabinet full the PG-FlexPlus Field Shelf a smaller 96-channel OSP hardened version of the COT can be placed next to an existing DLC cabinet. The field shelf accepts a universal DS1 feed over existing T1 HDSL HDSL2 or HDSL4 transmission and supports 6-channel and 24-channel line powered remotes. The field shelf also supports delivery of ADSL services.
