摘要

如何在窄带低比特率链路上进行高效的语音数据等多业务综合接入

并保证语音等实时业务的质量是目前多业务接入的一个重点问题.本文提出的动态时分多业务接入方案解决了Digital Data Network (DDN)专线上窄带压缩语音

ADPCM语音

传真

以及数据的同时接入问题

有效地解决了DDN专线上多业务接入的质量保证问题

提高了链路利用率.本文对于该方案的性能进行了分析

并与目前基于IP的多业务接入方案进行了比较.本方案能够提供目前的VoIP方案下所无法提供的语音

传真业务的质量保证

在多业务的支持上比VoIP更加简单

更有吸引力.

Abstract

In this paper

One Dynamic Time-Slot Allocation(DTSA) solution is proposed to enable the simultaneous access of voice

FAX and data on DDN leased line.This solution can guarantee the QoS of these services and also improve the utilization of the bandwidth.A thorough analysis of this solution's performance and the comparison with VoIP are given in this paper.The performance of this system shows that this solution can provide better QoS.Its simplicity makes this scheme more attractive than VoIP scheme.
