A circuit (10) and method for providing test and/or monitoring access to at least two telecommunication lines (18). This circuit (10) comprises at least one bus (12) and at least two primary branches (14) extending there from, at least one of the primary branches (14) being provided with at least one switch (26), which in a first state connects the primary branch (14) with the bus (12) and in a second state connects the primary branch (14) with ground. The method comprises the step of connecting only that primary branch (14), through which access to a telecommunication line 18 is to be established, with the bus (12). |
