Abstract

The PBXKAN system consists of dedicated microprocessors which replace the PBX and KAN modules of the Ericsson ARF-102 telephone exchange, improving the way of handling PBX groups and line classes. The microprocessor make it possible to perform other tasks such as traffic measurements and line supervision, besides reducing the switching time. These microprocessors are connected to an operator's terminal. The aim of the system is to improve old telephone exchanges, executing some important functions performed by the stored program control exchanges. It can also be adapted to the Siemens ESK-10000 and Standard Electric PC-1000 exchanges. The PBXKAN system is implemented and under industrialization, with some prototypes working full-time for more than a year. One of the main characteristics of the system is its capability of fault detection, localization, indication, and recovering.<>
PBXKAN:用于电话交换站现代化的基于微处理器的系统
PBXKAN系统由专用微处理器组成,取代了爱立信ARF-102电话交换机的PBX和KAN模块,改进了PBX群和线路类的处理方式。除了减少切换时间外,微处理器还可以执行其他任务,如流量测量和线路监控。这些微处理器与操作员终端相连。该系统的目的是改进旧的电话交换机,实现由存储式程控交换机完成的一些重要功能。它也可以适应西门子ESK-10000和标准电气PC-1000交换机。PBXKAN系统已经实施并处于工业化阶段,一些原型机已经全职工作了一年多。该系统的主要特点之一是具有故障检测、定位、指示和恢复的能力。
