2-wire analogue voice band interfaces; Terminal Equipment transmitting voice signals; Test simulation for level limitation requirements 2线模拟声带接口；传输语音信号的终端设备；电平限制要求的测试模拟

发布日期： 1998-05-01

本文件研究了使用单个伪语音信号作为水平限制要求的测试刺激的可能性。这适用于传输语音信号并具有2线模拟声带接口的TE。

This document studies the possibility of using a single pseudo-speech signal as test stimulation for level limitation requirements. This applies to TE transmitting voice signals and having 2-wire analogue voice band interface.
