  • Method and apparatus for analyzing events in a telecommunications system
    Patent number: 7304958
    Abstract: A method and apparatus for automated sectionalization of a DS1/DS3 data path based upon information received at a single location along the path. A test and monitor device is located at a point of demarcation between an LEC and an IEC. A Remote Module is located at a point of demarcation between the LEC and CPE. The test and monitor device is fully ANSI compatible. The information that is received is processed in a three step process in order to generate a “Sectionalizer Report”. In preparing the Sectionalizer Report, the information output from a filter is used to determine where particular Events originated.

  • Method and system for monitoring and testing a communication network
    Patent number: 7100092
    Abstract: A protocol analysis access system (“PAAS”) and a restricted access method for remotely monitoring and testing embedded channels in a signal communicated over a telecommunications network. The PAAS system is capable of accessing a signal from a network circuit through digital cross-connect systems (“DCSs”) or through direct connections. In case of restricted network access, the PAAS performs non-intrusive monitor-only function on the signal without interfering with or interrupting the data flow over the network circuit. In addition, the PAAS system is capable of performing non-intrusive conformance testing on a signal using a protocol analyzer. In case of non-restricted network access, the PAAS system allows full performance testing on a signal. The PAAS system functions are executed by an external command source from a remote network maintenance center via remote control links. The monitor-only and test results are reported back to the remote network maintenance center for further analysis.
