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

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-FlexPlusmicro-DLC system meets the challenge by providing quick and economical

distribution relief from central offices (CO) or DLC locations

The PG-FlexPlusmicro-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

Relief From the DLC Cabinet

The PG-FlexPlusCOT can be placed in a DLC cabinet, allowing line powered RTs to be placed deep into the outside plant (OSP)

Relief for the Crowded Cabinet

If the DLC cabinet full, the PG-FlexPlusField 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

Running the Numbers

The traditional approaches, cable upgrades, crossbox replacement and DLC installations, for adding network capacity beyond the DLC are expensive, time consuming and strand precious capital resources For example, the cost of adding 96-channels beyond an existing DLC can easily cost $50-$75K for a DLC installation, $10K for a new crossbox and $100K to add new cable

Figure 4: Conventional Approach New Construction Costs $160-$185

The ADC Alternative

Using the PG-FlexPlusmicro-DLC, adding 96-channels beyond an existing DLC costs less than $25K
