摘要： A telephony function is added to a communication and switching system (data network) 10 with computers 20, a general purpose server 11, etc coupled to it. Telephones 21 &c are coupled to the network through telephony modules 12-1 &c which convert signals from the telephones to digital form. A connection server unit (CSU) 16 is coupled to the network. Control information is passed between each telephone and the CSU to set up a call, and voice information is then passed through the data network directly between telephones. The CSU provides the control functions of a PABX, but the switching functions are in effect replaced by network routing. The telephone modules are of relatively simple nature. converting analog telephone signals (control and voice signals) into and out of digital form, and implementing a simple state machine which steps between the various states of the telephone (ie on-hook, off-hook, digit dialled, ringing, &c). Connections to the network can be made through multi-port concentrators 12, &c which can have both telephone modules and computer systems coupled to them.
摘要翻译：电话功能被添加到与计算机20，通用服务器11等耦合的通信和交换系统（数据网络）10。电话21和c通过将来自电话机的信号转换成数字形式的电话模块12-1和c耦合到网络。连接服务器单元（CSU）16耦合到网络。控制信息在每个电话和CSU之间传递以建立呼叫，然后语音信息直接通过数据网络传送到电话之间。 CSU提供PABX的控制功能，但切换功能实际上被网络路由替代。电话模块性质相对简单。将模拟电话信号（控制和语音信号）转换成数字形式和从数字形式转出，以及实现在电话的各种状态（即挂机，摘机，拨号，振铃和响铃）之间步进的简单状态机。可以通过可以具有电话模块和与其耦合的计算机系统的多端口集中器12和c来实现到网络的连接。
