Publication number: 20240291746Abstract: A multi-job, multi-job, multi-technician test process automation system is provided. The test process automation system allows a supervisory user to define and assign multiple jobs, where each job may include multiple tests. The jobs may be assigned to different technicians and or different testing devices. Once the tests are performed, the test process automation system may determine whether the test were performed properly. The test process automation system may further determine whether the testing devices have required configuration parameters and may additionally generate reports and business intelligence. The test automation system may be applied to any kind of modern network, including but not limited to, 5G, PON, cable, DSL, transport, and or any other type of network.Type: ApplicationFiled: February 24, 2023Publication date: August 29, 2024Applicant: Viavi Solutions Inc.Inventors: Michael D. GOTWALS, Walter L. MILLER

Patent number: 10873522Abstract: An apparatus and method for testing an upstream path of a cable network are disclosed. The upstream path is tested by capturing and analyzing upstream data packets generated by a specific terminal device. A test instrument is connected at a node of the cable network. The test instrument establishes a communication session with the headend, informing the headend of an identifier of the device that will generate the test upstream data packet. The test upstream data packet is captured and analyzed at the headend, so that the results of the analysis can be communicated back to the test instrument. To speed up the packet capturing and filtering process, the upstream data packets can be pre-filtered based on packet duration and/or arrival time.Type: GrantFiled: August 21, 2018Date of Patent: December 22, 2020Assignee: VIAVI SOLUTIONS INC.Inventors: Michael D. Gotwals, David W. Jones

Publication number: 20100087086Abstract: When connecting cable test equipment to standard F-connector style coax cables, a technician must use both hands to screw the cable under test into the test equipment or a test lead. In ideal conditions without gloves this is a rather simple task; however, a technician may have to repeat the procedure many times throughout a work day in extreme weather conditions, resulting in the technician having to repeatedly remove their gloves and expose their hands to the cold. A coaxial cable clip connector according to the present invention includes a smooth threadless connector, which fits into the cable under test, and an easily actuated clip, which fits over the coaxial cable connector housing to maintain a solid mechanical and electrical connection.Type: ApplicationFiled: October 6, 2008Publication date: April 8, 2010Applicant: ACTERNA LLCInventor: Michael D.
