For those large-scale rapid DSL network deployments, we offer the popular 3M™ ID3000™ family of integrated ADSL, ISDN and combi POTS splitters -- a 3M innovation. This enables a new configuration that moves DSL POTS splitters out of the DSLAM and onto the main distribution frame, saving much-needed rack and floor space, and reducing deployment time and cost by eliminating the large number of cables and blocks required to install DSLAM equipment. 3M central office solutions include 3M™ Blocks and Modules STG, 3M™ Frames RCP, 3M™ ID3000™ Blocks and QSA Blocks.
