In the context of digital subscriber line (DSL), a frame used where a competitive local exchange carrier (CLEC) or Internet service provider (ISP) is leasing dry copper pairs from the incumbent LEC (ILEC) for purposes of provisioning xDSL data services. The SPOT 1:8 SplitterDistribution FilterFeeder Fiber2:12:12:1 frame, and other hardware, is collocated in the ILEC central office (CO), generally in separately secured leased space.The ILEC cross-connects the individual leased circuits at the main distribution frame (MDF), and terminates them in the SPOT frame, where the CLEC or ISP connects them to the DSL access multiplexer (DSLAM). See also CLEC, CO, cross-connect, dry copper pair, DSL, DSLAM, frame, ILEC, ISP, MDF, and xDSL.
