Technische Daten - Call Traffic Generator

 
CAPACITY
  ISDN CTG supports up to sixteen boards (eight analogue boards, eight ISDN boards)
  • Analogue ports: four interfaces per board
  • Basic rate access: two or sixteen interfaces per board depending on the functions available on the B channels
  • Primary rate access: one or two boards for one interface depen-ding on the functions available on the B channels
 
 
PERFORMANCE
 
  • 180 simultaneous outgoing or incoming calls

  • 68 ports handled simultaneously

  • 72 000 calls per hou
 
 
CALL GENERATION MODE
 

Mixed or directed calls with Call distribution:

  • constant load
  • programmed load (calls per hour)
  • burst mode
 
 
TESTS AND MEASUREMENTS
 
  • Frequency generation
  • Programming of one or two frequencies to within 1 Hz in the300 Hz - 3400 Hz band, at a level of between 0 dBm and -33 dBm(minimum pulse width: 1 ms)
  • Frequency reception
  • Frequency measurement to ±12 Hz between 300 Hz and 3400 Hz
  • Attenuation measurement between 0 and - 33 dBm to ± 1 dBm
  • Silence tests (up to -33 dBm)
  • Continuity tests (outages detected above 70 ms)
  • Tone detection (programmable interrupt rates, 70 ms minimum)
  • G.821 tests
  • Charging tests (c wire, 12-16 kHz metering pulse transmission)
  • Time measurement to ± 1 msRouting tests
  • ISDN teleservice tests
  • Detection and transmission of voice messages
