1. Automatic Voice Frequency Test Sequences of ELQ 30A To learn more click on the selected topic! The Automatic Master-Slave Measuring mode is intended for the qualification of leased and dial-up voice frequency circuits. Two ELQ 30A connected to the ends of the tested line communicate over the tested line. ■ The Master initializes the measurements and collects the results. ■ The Slave performs the measurements according to the Master’s commands and sends the results back. Pre-programmed test parameter sets are provided based on recommendations: ■ ITU-T M.1020 special quality leased circuits with special bandwidth conditioning ■ ITU-T M.1025 special quality leased circuits with basic bandwidth conditioning ■ ITU-T M.1040 ordinary quality leased circuits Using pre-programmed test parameter sets ELQ 30A provides immediate PASS/FAIL qualification and detailed information about the reasons of failure.
