摘要
本文首先介绍ＩＴＵＴ最新建议Ｇ．８２６关于高比特率通道的误码性能参数和规范以及指标分配策略。然后阐述了我国关于假设参考通道（ＨＲＰ）的规定，ＳＤＨ网的误码性能和分配策略以及假设参考数字段（ＨＲＤＳ）的性能规范。最后分析比较了Ｇ；８２１和Ｇ．８２６建议的考虑原则和指标的差异并给出了一些定量计算结果作为参考。
Error performance parameters and objectives at high bit rate pathes and apportionment strategies in the latest ITU-TRec,G. 826 have been described. National HRP model,national apportionmentstrategies on error performance of the SDH network are also presented.Furthermore, consideration criteriaand performance objective differences between G. 82l and G. 826 are analyzed and comparied.Some quanti-tative calculated results are given as a reference.
