Systems and methods for using an audio cross-connect cable for remote mobile device testing

A method of automated testing a connection between a first location and a second location through a counterpart location, including:

• positioning a test harness near the counterpart location, remote from the first location and the second location,
• wherein the test harness includes a counterpart controller, first and second mobile phones, an audio cross-over cable connection between the mobile phones, and control connections between the test controller and the mobile phones, and
• wherein the audio cross-over cable adapts impedance and resistance of the connection between the first and second mobile phones to feed output of respective speakers to respective microphones, according to specifications for the mobile phone, and further inhibits transmission between the first and second phones of signals that match the mobile phone specifications for button presses;
• the counterpart controller receiving a test start signal and establishing a test connection between first and second equipment at the first and second locations, respectively, through the counterpart location, including:
• establishing a first test call connection between the first mobile phone and first equipment at the first location;
• and
• establishing a second test call connection between the second mobile phone and second equipment at the second location;
• whereby the equipment at the first and second locations have an audio connection over the audio cross-over cable;
• and
• conducting an automated test of audio communications between the first and second locations through the counterpart location.

A system for testing a connection between a subscriber mobile phone and a counterpart location with which the subscriber is having trouble, the system comprising:

• a test harness positioned near the counterpart location, remote from the subscriber and from a service technician,
• wherein the test harness includes a controller, first and second mobile phones, an audio cross-over cable connection between the mobile phones, and control connections between the controller and the mobile phones, and
• wherein the audio cross-over cable adapts impedance and resistance of the connection between the first and second mobile phones to feed output of respective speakers to respective microphones, according to specifications for the mobile phone, and further inhibits transmission between the first and second phones of signals that match the mobile phone specifications for button presses;
• wherein the controller is configurable to receive a test start signal from the service technician and establish a test connection between service technician equipment and subscriber equipment through the counterpart location, including
• establishing a first test call connection between the first mobile phone and the service technician equipment;
• and
• establishing a second test call connection between the second mobile phone and the subscriber mobile phone;
• and
• whereby the service technician and the subscriber have an audio connection over the audio cross-over cable.
