录音接口在程控交换系统上的实现

Realization of Recording Interface on Program Controlled Switch System

目前对程控交换机的录音主要是由外置录音系统通过并线的方式来实现,这种录音方式的前提是被录设备接口必须是标准接口设备,否则录音就很难实现。本文在程控交换机上的实现了一个标准录音接口,通过该接口可以实现标准录音系统对非标设备的录音。本文还通过分析录音的构成要素,借助智能网基本呼叫模型阐述了该技术的实现原理。

Currently, the recording to the terminal device of PBX is usually implemented by the third party recording system, by means of connecting parallel to the interface of target device. This approach of recording requests that the interface signaling of the ter- minal device be standard, which hardly can be satisfied in some customized devices. This article realizes a recording technology on program controlled switch system, which well resolves the previous problem, and elaborates the principle of the recording technology by analyzing of the model of BCSM （Basic Call Status Model）.
