QUALIFICATION OF xDSL LINES
■ Pre-qualification of copper wire pairs with physical parameter measurements 200 Hz to 35 MHz.
before installation of SVDSL, VDSL, ADSL 2+, ADSL, SHDSL or VF systems.
■ Automatic master-slave test sequences.
■ Line qualification with immediate PASS/FAIL indication.
■ Preprogrammed tolerance masks.
SoftWare options for xDSL line qualification
■ Single End Line Test.
■ Non- disturbing test of vectored lines.
■ Spectrogram Measurement.
■ Spectral Trace as Reference.
QUALIFICATION OF VOICE FREQUENCY CIRCUITS
■ Analogue measurements on leased or switched circuits 200 Hz to 20 kHz.
■ Analogue-to-analogue measurements on PCM systems.
■ Loop holding and dialing (pulse or DTMF) for dial-up circuit testing.
■ Test of ordinary or special quality circuits.
Software option for voice frequency measurements
