Automatic xDSL Test Sequences of ELQ 30A
ELQ 30A provides automatic bi-directional Measurement of principal characteristics of the
subscriber line using two instruments. They are connected to the ends of the tested pair in
MASTER-SLAVE arrangement. The two instruments communicate over the tested pair.
■ The Master initializes the measurements and collects the results.
■ The Slave performs the measurements according to the Master’s commands and sends
back the results. ELQ 30A can be programmed as MASTER or SLAVE as well.
Pre-programmed test parameter sets are provided containing:
■ Tolerance masks for Loss, LCL, Return Loss, Impedance measurement
■ Principal system parameters for VDSL2, VDSL1, ADSL2 +, ADSL, ADSL G LITE
READSL2, ADSL G LITE, ADSL G.LITE2, SHDSL, HDSL, ISDN etc. systems.
Using pre-programmed test parameter sets ELQ 30A provides immediate PASS/FAIL
qualification and detailed information about the reasons of failure.
