Functional Description

   The EZ-Tester performs comprehensive testing of DS1, 4-wire DDS circuits and equipment, plus optional line parametric testing. As a T1 test set, it can be configured with single or dual T1 test ports with single or paired transmitters and receivers. The receiver section can monitor customer data or received test data to identify current line coding and framing information, and to detect and display standard alarms and errors. The transmitter section can be used to send standard test patterns, inject errors into the data stream, and generate loopback commands to NIUs and CSUs to enhance isolation of network impairments. Dual transmit and receive jacks allow simultaneous bidirectional monitoring and the ability to perform a drop and insert with a single instrument.

   As a DDS test set, the EZ-Tester provides full out-of-service testing capabilities for 4-wire DDS local loops. When connected to terminate a 4-wire DDS local loop, the test set can auto configure to match the loop rate, identify an existing test pattern, and confirm the status of the secondary status and test pattern. It will also detect alarm and error conditions; transmit typical DDS test patterns; inject errors and alarms; decode control bytes; perform local or remote loopback functions; and allow frame relay testing from a DDS access point. The optional line parametric test feature enables the test set to perform line level and frequency measurements, noise measurements, spectrum analysis, time domain reflectometry tests, and test lead calibration.
