The GL's Voice/Data Recorder is used to manually capture voice or data over a 2-wire Analog interface. Using the Dual UTA, USB T1 E1 Analyzer, or a sound device, one can non-intrusively 'tap' into the analog 2-wire line and capture the bi-directional voice or data signal to a single PCM file. The Dual UTA or USB T1 E1 Analyzer provide very accurate capture of the signal suitable for Fax and Modem demodulation, whereas an external sound device is adequate for voice signals. Important applications include: Modem and Fax Data Analysis GLInsight, VQuad for PDD (Post Dial Delay) & PRD (Post Ringback Delay) Measurements and a Voice Band Analyzer
