Abstract: A cost-effective technique for inserting a switching module into a line pair of a local telecommunications network is disclosed. In particular, the illustrative embodiment does not replace a punch-down block at a cross-connect, but rather inserts the switching module between the modular connectors that are usually co-located with the punch-down block and that connect the cable pairs to the punch-down block. In other words, the illustrative embodiment provides for a technician to disconnect a pair of modular connectors and to insert a switching module between them, wherein the switching modules inputs and outputs are provided via modular connectors.
