T-BERD 209OSP
FEATURES
Introduction
T
he TTC® T-BERD® 209OSP meets the exclusive testing requirements of the outside plant technician. Combining T1/ISDN/DDS/HDSL BERT, TDR, and DVOM, the T-BERD 209OSP is a complete tool for qualifying and troubleshooting digital loops. By adding optional FT1 support, pre-programmed intelligent equipment commands, and HDSL loop qualification, you have the most flexible, all-in-one solution for outside plant testing.
• Full Span Transmitter and Receiver Identify marginal troubles with standard T1 stress patterns at various output levels. Easily access signal and error information. Service-effecting results are automatically displayed in SUMMARY RESULTS category. • Cable Qualification Identify cable impairments such as opens, shorts, bridged taps, load coils, splits, crimps, partial opens, grounds, and resistive shorts. Distance to fault is displayed in feet. • Automated Testing Qualify T1 spans at the push of a button with AUTOTEST, automated MULTIPAT™ and BRIDGTAP™ stress patterns, and automatic receiver configuration. • Repeater Adapter Cable-in once. Complete test access to repeatered spans without the use of several cumbersome cables. • Graphical Display Control test access with the push of a button. View graphical TDR response to verify cable impairments. • Flash Memory Complete field software upgrade in minutes. • Lead Acid Battery Five hours of testing time with lead acid dependability. • Rugged Enclosure The rugged, NEMA-4X-compliant design keeps the harsh elements out and the unit working, no matter what the testing conditions.
The T-BERD 209 OSP is the ideal outside plant test set.
