Latest Patents
One of Engdahl's latest patents is a performance monitoring and test system for a telephone network, specifically designed for DS3 level access. This innovative system provides selective and hitless bit overwrite capabilities in any of the embedded DS1, DS0, and subrate channels within a DS3 signal. The system allows for the testing of multiple DS0 and subrate channels through asynchronous time slot interchange, in conjunction with the recombiner. Additionally, it features a lookahead reframer for framing to the DS3 signal and a facilities data link (FDL) handler for capturing FDL channel data in every DS1 channel. A high-speed bit-for-bit comparison is integrated to ensure 1:1 fault protection, while full-time performance monitoring on DS1 and DS3 signals is conducted by a shared resource. This invention provides an integrated approach to synchronization measurement and relative synchronization.
