Information

General The portable hand-held EZ-TESTER® DS, is designed to perform in-service and out-of-service testing and monitoring of DS1circuits, and out-of-service testing of 4 -wire DDS communications equipment and circuits. It is used during installation to verify acceptable performance and during maintenance to isolate problems to the communications components or end user equipment. The EZ- TESTER DS incorporates the following design features: Rugged metal case minimizes damage from drops and similar accidents Weather-resistant construction protects Test Set in wet or dusty field conditions Menu driven setup and operation for ease of use Auto configuration feature determines line characteristics and reduces setup time Can be configured as a single or dual line Test Set. Dedicated storage for eight custom test setups Includes 26 stored test patterns vital to DS1 testing Controls and simulates CSU / NIU loopback functions Includes built in speaker, with jack for an optional headset Provides DS0 channel access Software upgrades can be field installed using OnCall® with a telephone line and modem 1.2 Functional Description The EZ-TESTER DS 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 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 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 directional monitoring and the ability to perform a drop and insert with a single instrument. As a DDS Test Set, the EZ-TESTER DS 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 autoconfigure 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. During operation, a capture memory stores selected events, periodic test summaries, and end of test results. All events are date and time stamped from an internal real time clock and can reviewed locally, remotely, or output to a printer. Eight user defined test setups can be stored and recalled for ease of operation. An auto configuration function is available to determine line characteristics. Remote control operation and printer output is provided through an auxiliary RS-232 port.
