摘要： A DSL splitter providing test access to an interconnected subscriber loop and method are disclosed. The DSL splitter in a first test mode, provides access to allow testing of an interconnected subscriber loop by way of a DSL input. A disconnect in series with an associated low pass filter (LPF) disconnects POTS input. Such a splitter may similarly provide access to allow testing of the subscriber loop by way of the POTS input in a second test mode. In this second test mode, a by-pass by-passes the LPF, and a disconnect may disconnect an associated high pass filter (HPF) and DSL input. Preferably, the splitter only assumes its test modes after receipt of authorization from the other provider. The splitter may be controllable by way of a control circuit having an access port used to receive commands to have the splitter assume its normal, or first or second test mode. The splitter may assume its normal operating mode from a test mode, after expiry of a timeout timer.
