Abstract: The technology includes a method, computer medium, and system for testing audio quality of a transport segment between two core networks. A first virtual test agent (VTA) selects a Mobility Management Engine (MME) corresponding to an eNodeB served by a first core network for routing a second call, through a Serving Gateway (SGW) assigned by the MME for audio communication with a tester terminus. The second call is made from the first VTA to a second VTA at a second core network over a transport-segment-under-test that connects the first and second core networks, So that a tester can evaluate audio quality over the transport-segment-under-test. The first VTA makes a first call to a tester appliance, makes a second call, over the transport-segment-under-test, to the second VTA implementing audio evaluation, by signaling the MME, and bridges the first and second calls by relaying audio during a test of subjective audio quality.

Abstract: The technology includes a method, computer medium, and system for testing transport audio quality irrespective of tester location. The technology involves a virtual test agent (VTA) selecting a Mobility Management Engine (MME) for routing a second call through a Serving Gateway (SGW) assigned by the MME for audio communication with a tester terminus over a transport segment under test, so a tester can evaluate audio quality over the transport segment under test. The VTA makes a first call to a tester appliance, and makes a second call, over the transport segment under test, to the tester terminus by signaling the MME. The VTA bridges the first and second calls by relaying audio during a test of subjective audio quality, whereby the bridging assures that the relayed audio in the second call continues to be relayed over the transport segment under test and not re-routed by core network components.

Abstract: The disclosed technology teaches testing voice connection routing over 911 circuits as if voice calls originated from an E911 device in coverage areas of cell tower locations, without requiring a physical presence of the E911 device in each coverage area. A remote test agent audio bridge and tester originates a first call to a test user with a first phone number, creates a media bridge, emulates an E911-compliant mobile device to originate a second call to a 911 operator, relays audio over the media bridge as a verbal exchange between the first and the second calls, and logs an evaluation of the verbal exchange. The emulation includes spoofing a call origination from an origination location being tested, the spoofed origination location being within coverage of an originating cell.

Abstract: The technology includes a method, computer medium, and system for remote testing over-the-air (OTA) audio quality using a test platform positioned at core network, the test platform comprising first and second cellular handsets and bridging logic that interconnects, controls, and bridges the first and second cellular handsets. The method includes triggering the bridging logic. The bridging logic initiates a first call over the first cellular handset to a tester, and initiates a second call over the second cellular handset to a destination, wherein the second call is initiated over-the-air. The bridging logic and the first and second cellular handsets are positioned in a location that causes routing by a cellular network of the first call over a segment under test. The bridging logic bridging audio between the first and the second calls, including relaying audio. The tester determines that the second call was established based on the relayed audio.

Abstract: A blade accessory for use with heavy equipment to permit changeability between a bucket and a grading blade, the blade accessory comprising a frame, means for mounting the frame to the vehicle, means for attaching a bucket to the frame to permit pivotal movement of the bucket with respect to the frame about a vertical axis along with means to pivotably move the bucket in a horizontal plane. Means to mount the blade member on the front of the bucket are such that the blade member may be angled when the bucket is moved in the horizontal plane.

Abstract: A table tennis game for four players comprising a table having an upper playing surface which has intersecting nets which divide the upper playing surface into four sectors shaped substantially as quadrants, each such sector comprising the individual playing areas for each of the four individual players. A circular member lies in the center of the table at the intersection of the four nets for purposes of receiving insufficiently hit table tennis balls, with such circular member being utilized as part of the game play scoring.
