  • 600 ohms and 900 ohms
  • 32-bit processor, DSPs, and flash memory to ensure full computing and upgrading capabilities
  • Programmable call progress tones
  • DTMF, MF R1, pulse dialling
  • Flexible call sequences
  • Generate 5600 calls per hour per subsystem
  • Test duration to be random or fixed from 1 s to 5 years
  • Verify that speech path is established and retained for duration of call
