The TAS 192 is a professional audio signal processing unit engineered for modem and fax testing applications requiring accurate emulation of telephone network conditions. It delivers advanced signal conditioning through programmable impairments control and dual central office emulation, meeting EIA/TIA standards including TSB 37A. The unit supports native 4-channel audio processing at sample rates from 32 kHz to 192 kHz with >105 dB dynamic range and 105 dB
• THD+N: <0.1% (0–40 kHz)
• Noise floor: 20 Hz–40 kHz, flat across 32 kHz–192 kHz
Network Emulation
• Frequency response: Enhanced for V.34 and V.34+ modem testing
• Supports 2-wire dial, 2-wire private, and 4-wire private line configurations
• Mixed-mode operation: 4-wire at one station, 2-wire at the other for cellular modem and remote access server testing
• Cascadable for Digital Loop Carrier (DLC) and PBX environment simulation
