一种多功能低速数据复用设备

A Multifunction Low Bit Rate Data Multiplexing Equipment

提出了一种组合方便、应用广泛的低速数据复接设备的实现方案。在介绍了系统组成和构造特点的基础上，着重分析和研究了Ｘ５０数据复用、基群信道接口及同步检测等部分的电路原理及实现特点。通过实际线路试验，该方案完全达到了预定的设计目标。

This paper presents an implementation of multiplexing equipment, which is used widely and flexibly in low bit rate data communications. Based on the introduction of the system composition and construction characteristics, this paper analyses in detail the hardware implementation for the following parts: X.50 data multiplexing, primary rate interface, synchronous detection. It is demonstrated by experiment on real lines that the proposed approach got the expected results.
