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).


Features:

    Measurement & Signal Detection
  • Line voltage, loop current, common mode voltage
  • Ringing frequency, level, duration, DC offset voltage
  • AC RMS level, frequency, THD+N
  • DTMF digit level, twist, frequency error, duration
  • CAS/DTAS level, frequency, duration
  • Metering pulse level, frequency, duration
  • V.23 and Bell 202 FSK based Caller ID
  • Pulse dialing, line flash, polarity reversals

  • Signal Generation Capabilities
  • DTMF tones with arbitrary frequency, level, and duration
  • V.23 and Bell 202 FSK modulated data
  • One to four tones of arbitrary frequency, level, and duration
  • Wavefile playback
  • Broadband noise generation
  • Echo generation

  • Line Interface Capabilities
  • Off hook DC resistance from 50 to 1000 ohms
  • Resistive AC impedance from 200 to 1000 ohms
  • 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:

  • 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 (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)
  • 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.
