Terminal Equipment Simulator - Overview
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).

  • Complex AC terminations for TBR-21, German ZR
  • Programmable ringing loads
  • Programmable flash timing and pulse dialing

Applications:

  • Verifying Caller ID signal generation from CO's, PBX's, and line simulation equipment.
  • Measuring general telephony signals such as DTMF, ringing, line flash duration, and line voltage.
  • 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.

  • V.21/T.30 Signal Analysis: AI-ET005
    The V.21/T.30 Signal Analysis option allows the AI-5620 to decode the V.21 signaling between two T.30 compatible fax machines. This option provides an easy method to compare what each end of the fax transmission sent and measures the timing to determine errors in connectivity. The waveforms can be viewed and analyzed for problems in the time domain or the reports used to examine the HDLC frames present for errors in the transmission format or latency. Note: This option requires that the AI-5620 also have the AI-ET004 option installed.

  • 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)
    • 200 ohm + (680 ohm || 100 nF) (China Zr) GBT15279-2002


  • Alternate Ringer Loads:
    By default the AI-5620 comes installed with ringer loads conforming to the TIA-1063 standard (1 REN = 8.0 uF + 6.8k). As a factory installed option, the AI-E502 ringer loads will replace the default loads with one of the following alternates:

    • AI-E502-Aus:
      Australian AS/ACIF S004:2008 (1 REN = 1.0uF + 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)
    • AI-E502-BT:
      British Telecom BTNR315 (1 REN = 0.5uF + 6.8k)
    • AI-E502-NZ:
      Telecom New Zealand PTC220 (1 REN = 1.0uF + 8.0k)


  • Additional One Year Warranty: AI-K001
    The standard product support and warranty period for the instruments is one year. This option increases the parts and labor warranty period for another year to a total of two years from date of purchase on the instrument.


  • Additional Three Warranty: AI-K003
    The standard product support and warranty period for the instruments is one year. This option increases the parts and labor warranty period for three more years to a total of four years from date of purchase on the instrument.
