摘要
利用段开销中未定义字节传送数据的开销扩展盘，已成为武汉邮电科学研究院的SDH传输设备系列产品的特色功能设置。通过开销扩展功能，用户还可以在监控终端读或写某个开销字节。本文介绍了开销扩展功能和研制。
We designed a digital circuit unit that makes use of undefined section overhead to transmit data signal. By use of this unit, it is possible to write and read some bytes in section overhead from terminal workstation. These are some of the feature functions of SDH series products of WRI. Here we describe the function and the research work of this unit.
