1. Automatic Voice Frequency Test Sequences of ELQ 30A+
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.
