The T-BERD 224 mainframe is a channel access test set used to monitor the status of in-service circuits, troubleshoot out-of-service circuits with a complete set of stress patterns, and to isolate faulty equipment or circuit impairments. The T-BERD 224's field-upgradeable software options enable you to build a custom set for every testing need. The T1 BERT Option enables you to stress test the entire T1 circuit. Test the error tolerance of network equipment by inserting single, burst, variable-rate BPVs, frame errors, and logic errors.
 

Features:

  • Automatic configuration and results summary functions immediately identify framing, pattern, and error status. All controls and indicators are on the front panel to save time in training, test setup, and operation
  • Loop smart jacks and CSUs with in-band and out-of-band loop codes to verify T1 circuits with a single test set
  • Detect differences in system timing between two T1 inputs. Immediately identify and isolate network synchronization problems
  • Sectionalize the T1 link with non-intrusive bidirectional monitoring. Count biploar violations (BPVs), frame errors, and cyclic redundancy checks (CRCs). Measure the receive signal levels (volts, dBdsx) and frequencies for both T1 inputs
  • Verify extended superframe (ESF) to D4 conversions, and monitor with split framing on the T1 inputs
  • Monitor on hook/off hook conditions and drop selected DS0s to audio output or perform further testing with other T-BERD 224 option packages
  • Test the full T1 span with a wide range of test patterns
  • Drop (receive) and insert (transmit) on any of the 24 channels from any T1 access point, while maintaining service on the remaining 23 channels
