| 20100146367 | SYSTEM FOR TESTING THE UPSTREAM CHANNEL OF A CABLE NETWORK - A system for testing a portion of a cable network provides a pattern generator, addresser, forward error corrector, and comparator. The system is particularly adapted to testing the upstream channel in a cable network. The pattern generator generates a test signal. The addresser addresses the signal to a known server and also instructs the known server to return the test signal to the test system. The forward error corrector corrects errors introduced in the test signal in transmission from the known server to the test system. The comparator then compares the returned test signal to the originally transmitted test signal to determine the performance of the back channel. Preferably, the comparator uses a bit error rate test to determine the performance of the back channel. | 06-10-2010 |
| 20090287964 | INTERNET ACCESSIBLE TEST SYSTEM - An Internet accessible test system including: providing a remote client having an Internet connection; and exercising a tester function across the Internet connection by the remote client. | 11-19-2009 |
| 20090254956 | COMMUNICATION SIGNAL CHARACTERISTIC MEASUREMENT SYSTEM - A communication signal characteristic measurement system comprising: detecting a quiet line including: storing a specific characteristic data, detecting a vertical synchronization pulse in the specific characteristic data, and applying an eight line delay in the specific characteristic data; and displaying a data set showing the quiet line relative to the vertical synchronization pulse. | 10-08-2009 |
| 20090213738 | TEST SYSTEM WITH USER SELECTABLE CHANNEL - A test system comprising: acquiring an upstream channel descriptor list; entering a pause network state when the upstream channel descriptor list is completed; and selecting a particular channel from the upstream channel descriptor list before exiting the pause network state. | 08-27-2009 |
| 20090213737 | TEST SYSTEM WITH RETURN SWEEP LEVEL SETTING - A test system comprising: providing a conditioning circuit; cabling a cable modem termination system to the conditioning circuit; signaling an initial ranging request to the cable modem termination system; and determining a transmission power limiter by the conditioning circuit monitoring a network for detecting a cable modem termination system response to the initial ranging request. | 08-27-2009 |
| 20090149173 | WIRELESS NETWORK PROFILING SYSTEM - A wireless network profiling system is provided including providing a base station tester for attaching to a cellular base station, using a global positioning system for logging the position information of the cellular base station, using the base station tester for collecting a parametric information from the cellular base station and using a mobile handset emulator for transferring the parametric information and position information for analysis and storage. | 06-11-2009 |
