Abstract: A method, system, and apparatus for attenuating a dialing confirmation tone includes receiving an enable signal from a tactile user input device, generating at least one dual-tone multiple frequency (DTMF) tone, and communicating the at least one DTMF tone to a telephone line. The method further includes attenuating a signal level of the at least one DTMF tone by a predetermined amount to produce at least one attenuated dialing confirmation tone in response to receiving the enable signal, and communicating the at least one attenuated dialing confirmation tone to an audio output device.

Abstract: A real loop and method for using the loop for testing sidetone signal level are provided. The loop is modeled from a coil of cable to represent a straight wire loop. Several conducting wires in a cable may be used. The cable may be configured in a coil and may have a first end and a second end exposed for electrical connections to an even number of wires. Each wire in the even number of wires may be capable of being identified as the same wire on each of the first and second ends of the cable. One or more pairs of wires in the even number of wires may be electrically connected to form an electrical loop. An electrical current passes in opposite directions in the wires in each pair of wires.

Abstract: The present invention is directed to an acoustic signal transfer device for transferring an acoustic signal produced by a telephone handset in a test setup. The device comprises a handset holder, a microphone holder and an acoustic pathway that extends from the handset holder to the microphone holder. The handset holder supports a telephone handset and allows an acoustic signal to travel from the telephone handset to one end of the acoustic pathway. The microphone holder supports a microphone and allows an acoustic signal to travel from a second end of the acoustic pathway to the microphone. A system and method for utilizing the acoustic signal transfer device in a radio frequency immunity test for a telephone are also disclosed.
