摘要： This invention precisely and automatically measures the protection switch time of modern communication networks such as the SONET or SDH standard. An automated precision measurement device is provided which uses digital error detection and gated counter techniques to accurately measure the time required for a network element to switch from a defective line to a protected line for the purpose of delivering error free service to customer premises. The device accepts a line side signal, demultiplexes a payload test pattern from the standard mapping, and analyzes the payload pattern for errors. If errors are present, the device further measures the time that the errors persist (e.g., the time between the first error present to the last error present, inclusive). If the measurement was made during a protection switch event in the network element, then this time represents an accurate measurement of the protection switch time that affected the service. Alternatively, the device will measure the signal with embedded test pattern as demultiplexed from the terminal itself yielding a measurement from a customer interface point.

摘要： A protocol and bit rate independent test system for detecting bit errors on a digital communications channel regardless of format or rate, comprising a receiver for receiving an input, a clock recovery unit, a threshold sampling circuit for providing at least two threshold detectors for respective two sampling points including at least one static sampling point positioned proximate to the center of an eye pattern and at least one dynamic sampling point, the output of which are sampled by the recovered clock and if the signal passes between the thresholds, an error signal is generated and counted.

摘要： A novel high speed telecommunications testing apparatus and method which utilizes field programmable gate arrays to produce dynamic test modules for DS1, DS3, SONET and ATM signals interconnected by a high speed switching fabric. The high speed switch permits the direct exchange of signals from one test module to another thereby permitting simultaneous testing of different communications line protocols and further provides for multiple tests on a single data stream. Individual line interfaces are provided for DS1, DS3, and SONET lines which terminate and frame incoming and outgoing signals. Data exchange between modules in accomplished through the high speed switch fabric.
