Informacja

The T-BERD 305 is a comprehensive DS3 Analyzer that conducts simultaneous error and performance analysis. The T-BERD 305 is used for out-of-service testing or in-service monitoring, and is suited for testing DS3 communications across any medium, including coaxial cable, fiber optic cable, and microwave systems. The T-BERD 305 features a simultaneous array of logic, bipolar violation, frame, and parity error measurements. The ability to simultaneously measure error conditions means that the user can obtain a complete set of measurements in a single test. These measurements can also be viewed without interrupting a test in progress. The T-BERD 305 is packaged in a rugged aluminum case weighing less than 15 pounds, ensuring portability for use in the field. 1.3 SUMMARY OF KEY FEATURES The following list describes the T-BERD 305’s features and characteristics. • Simultaneous Result Accumulation of error measurements, performance measurements, and signal measurements allows testing time to be minimized without compromising the thoroughness of the test. • Frame and Parity Error Counting can be performed on live data, providing the user with the capability to conduct in-service monitoring. • Threshold Error Seconds is a count of the number of seconds in which the error rate exceeds a user-defined threshold, from 102 to 109. This feature allows unmanned and long-term testing when exception reporting only is desired. The threshold can be defined for logic, BPV, and frame error rates. • Error Measurements include logic, bipolar, and frame errors as well as associated error rate, errored second, and percent error-free seconds calculations. An optional remote control Interface additionally provides remote testing capabilities. ® Pattern Slips Count correlates slips and error bursts. When a slip is detected, the T-BERD 305 counts the slips and the resultant errors, but instantaneously resynchronizes to the input pattern. By maintaining synchronization and keeping the slips and errors count, the T-BERD 305 allows quick isolation of pattern slips as the source of errors. • The Insertion of Single and Burst Errors simulates live traffic conditions and tests the recovery time of DS3 equipment. The burst characteristics are user-defined and the burst error rate can be set from 10-2 to 10The burst duration can be set from 0.025 seconds to 5 seconds in 0,025 second increments. • A Signal Analysis Option is used in conjunction with error and performance analysis. Complete with signal level, signal power, and frequency measurements, this option can be used to check DS3 signal level during installation and to correlate error bursts with level dropouts or frequency variations. • A DS1 Drop Option allows simultaneous monitoring of the DS3 signal and any one of the DSl signals within it, The DSl signal is presented at a rear panel WECO 310 connector, which interfaces with a variety of DSl test instruments. • Extended-Length Pseudorandom Patterns support thorough stress-test- ing of DS3 equipment and systems. • A Printer Interface permits automatic printouts to be initiated by test completion, errored seconds, or regular time intervals. ® Remote Control Option enables unmanned testing or long-term monitoring from a remote site. • Thru Data Error insertion permits burst errors to be inserted on live traffic, thus testing the tolerance and recovery time of receiving equipment, and exercising system alarms and protection switching.
