The AI-5620 simulates a single port two wire analog TE (Terminal Equipment) or CPE (Customer Premise Equipment) device. It is designed to measure and analyze signals generated by a CO (central office) line card, VoIP terminal adapter FXS port, or any device utilizing a SLIC (subscriber line interface circuit).

• Testing SLIC characteristics using adjustable load resistances, ringing loads, and AC terminations.
• Monitoring telephone line signals.

Options:

• Waveform Capture: AI-ET004
  The waveform capture option provides the ability to continuously download waveforms from the AI-5620 to the PC. The waveforms can be viewed and analyzed for additional measurements. Additionally, a live FFT view allows monitoring of AC signals in the frequency domain.

• Additional Line Impedance: AI-E701
  Adds a third complex impedance to the two built in complex impedances of TBR-21 and German ZR. Common impedance selections include the following:
  
  
  • 82 ohm + (600 ohm || 68 nF) (TBR-38 "a")
  • 220 ohm + (1800 ohm || 150 nF) (TBR-38 "c")
  • 370 ohm + (620 ohm || 310 nF)
  
  
  
• Alternate Ringer Loads:
  By default the AI-5620 comes installed with ringer loads conforming to the TIA-1063 standard. As a factory installed option, the ringer loads can be changed to one of the following alternates:
  
  
  • AI-E502-Aus:
    Australian AS/ACIF S004:2008 (1 REN = 8.0uF + 4.0k)
  • AI-E502-ETSI25:
    ETSI 25 Hz TS 101 952-1-1 (1 REN = 2.2uF + 2.7k)
  • AI-E502-ETSI50:
    ETSI 50 Hz TS 101 952-1-1 (1 REN = 1.0uF + 2.7k)
  
  
  
• Additional One Year Warranty: AI-K001
  Increases the parts and labor warranty period from the standard one year to a total of two years from date of purchase.
  
  
• Additional Three Warranty: AI-K003
  Increases the parts and labor warranty period from the standard one year to a total of four years from date of purchase.
