Abstract

According to the invention, a user connection cable (TAL) that is to be associated with a user connection circuit (SLIC) and is used for connecting at least one user (TN) to at least one communication network is verified regarding switching on of a positive distribution voltage in the strands (a, b). The user connection circuit (SLIC) is initially switched to the silent interval mode and a test impedance (I) is switched between the strands (a, b) of the user connection cable (TAL), whereupon the current (i) flowing across the strands (a, b) and the voltage (u) to ground of a strand (b) are measured. Advantageously, the measurements are taken via measuring devices disposed on the user connection subassembly (SLMA).
