A professional network test set that delivers high-quality VDV functionality for technicians.

Seven testing functions include:
  • Data indication – warns when data is present
  • Voltage indication/measurement – identifies potential line problems
  • Current (mA) indication/measurement – verifies sufficient line current
  • Caller-ID with Call Waiting CID – verifies functional service
  • DTMF Digit Grabbing – isolates faulty customer premise equipment
  • Detects dial tone, places and receives calls
  • Polarity
