【摘要】 信令分析仪采用高阻抗跨接方式接入承载信令链路的2 048kbit/s接口电路,可以保证信令仪在长距离监视设备中准确无误地接收到2个方向的信息,而且不影响链路的正常工作。给出了无源高阻适配器的设计方案,并在理论与实际上分析验证了其可行性,有助于从事程控交换的工作者形成可操作的数学模型。更多还原

【Abstract】 The signaling analyzer which connects the 2 048 kbit/s interface circuit carrying signaling, can not only guarantee that the signaling analyzer to receive the two in-and-out aspects accurate message but also not to interrupt the circuit’s normal running. This paper gives the designing scheme of the high impedance adapter without power supply, and analyzes the feasibility in theory and practice.更多还原
