Method and apparatus for monitoring one or more telecommunications systems supported by a wireless device with respect to which the wireless device is in an idle mode while the wireless device is in a connected mode with respect to another supported system. The apparatus includes an air interface, at least two access means for providing the wireless device with access to at least two supported telecommunications systems, and a circuit having a connection to the air interface and a plurality of connections to the at least two access means. The circuit provides a low attenuation between the air interface connection and a connection to the access means that provides the wireless device with access to a system with respect to which the wireless device is in a connected mode, and further includes means for setting the circuit to at least two states, wherein each of the at least two states provides a different attenuation between the air interface connection and one of the plurality of connections to the at least two access means.
