Information
The T-BERD 310 is a portable test instrument that can test and analyze SONET, DS3, and DSI transmission systems from SONET, DS3, and DSI access points during circuit installation, acceptance testing, and fault isolation. The T-BERD 310 can generate and receive test patterns for out-of-service testing, or monitor SONET, DS3, and DSI circuits without service interruption. Options can be added that enable the T-BERD 310 to perform DSI testing, drop and insert a DSI channel on a live DS3 line, drop El channels, drop and insert OC-3, OC-3c, DS3 and DSI payloads on SONET signals, and perform optical media tests. The instrument can also be optioned to test and analyze ATM traffic on SONET, DS3 and DSI transmission systems. The following information describes the standard and optional features for the T-BERD 310, 1.2,1 The T-BERD 310 offers the following standard features: DS3 Pulse Shape measurement quickly isolates cable faults that are not readily evident through traditional BERT tests. Intermittent errors on DS3 hand-offs are commonly caused by improper or loose crimps or degraded or damaged coaxial cable. Pulse Shape measurements can also identify when too much or too little coax has been installed, or if the line build-out has been improperly set. These types of errors can be the most time consuming for field technicians to find and often result in "No Problem Found" resolutions leading to poor customer service or future call-backs. Enhanced user Interface provides easy to use controls and indicators designed to focus on DS3, SONET, and ATM circuit testing. Multiplexed C-bit parity and M13 framed operating modes enable the T-BERD 310 to insert DSI D4 or ESF formatted test patterns or loop codes into the DS3 signal. Automatic configuration mode allows the T-BERD 310 to configure itself automatically to the received DS3 signal framing and pattern. Standard and programmable DS3 test patterns are selectable from a front-panel switch. Five side-panel DS3 outputs provide the same signal as the front-panel output jack. Simultaneous test result accumulation minimizes the time needed to test for DSI, DS3, or SONET signals. A summary test results category displays key non-zero and “out-of-spec” test results, eliminating the need to search through long lists of test results. Pattern slips can be counted between the transmitted and received signal by testing the circuit with pseudorandom test patterns. Logic error, BPV, and frame error insertion capabilities enable the T-BERD 310 to simulate errors as they occur. Errors can be inserted singly, in bursts at preselected durations and error rates, or continuously at preselected error rates. Connecting a printer to the T-BERD 310 allows generation of test results, signal status and alarm messages, front-panel switch configurations, and pulse shape graphs. The T-BERD 310 comes equipped with an RS-232-C serial Interface or optional IEEE-488 Interface (IEEE-488 Option). An internal print buffer allows printouts to be stored until a printer is connected to the T-BERD 310, The print buffer is battery-backed which allows power to be turned off without losing the printout information. Customized test result printouts can be created for specific tests. Remote control operation enables the T-BERD 310 to be installed at a remote location or in a manufacturing test facility. An RS-232-C serial Interface or optional IEEE-488 Interface (IEEE-488 option) is available for remote control operation. Multiple displays enable the operating mode, test pattern, and two test results to be displayed on the user Interface at the same time. Audible alarms can be used to indicate pattern synchronization, threshold errored seconds, and any other error event. DS1 channels can be dropped from a DS3 signal to the DS1./DS0 Analyzer Option or an external DSI Test Set. DS2 frame synchronization and loss detection LEDs provide status and alarm indications on the user Interface. Far-end alarm and control (FEAC) messages can be monitored and displayed on the user Interface and reported in a printout. FEAC messages can also be selected and transmitted from the T-BERD 310,
