Installing the POTS Splitter Wiring
The local loop ends at the punchdown block or NID. Wiring must be connected from the
customer premises (CP) side of the punchdown block or NID to the DSL jack. Typically,
the punchdown block is installed in commercial locations and the NID is installed in
residential locations.
The following is an example of a punchdown block.
