    摘要： A distributed digital telephone system is provided wherein a plurality of telephone consoles have instant access to a plurality of telephone lines wherein in all of the connections within such a system are non-blocking. The system architecture is that of a reverse ratio PBX in which the number of lines exceed the number of consoles and each handset has a reserved time slot on time division multiplex (TDM) highways for internal node or group connections. Accordingly, each handset is guaranteed access to idle lines within any given switching node. The distributed architecture is distinguished from central processing where all call processing is directed through a centralized point. In this decentralized system, all signal conditioning, protection, sensing and control are provided by the resource interface with the TDM highways. Resource data reporting is continually provided to all the resources connected to the system that require it. Redundancy of critical resources is provided in such a manner that only the portion of the system where a fault occurs is disabled while the remainder of the system continues to operate.

    摘要翻译： 提供了一种分布式数字电话系统，其中多个电话控制台具有对多个电话线的即时访问，其中在该系统内的所有连接都是非阻塞的。 系统架构是反向比率PBX，其中线路数量超过控制台数量，并且每个手机在用于内部节点或组连接的时分复用（TDM）高速公路上具有保留的时隙。 因此，每个手机被保证访问任何给定交换节点内的空闲线路。 分布式架构与所有呼叫处理通过集中点指向的中央处理区分开来。 在这种分散的系统中，所有信号调理，保护，感测和控制都是通过与TDM高速公路的资源接口来提供的。 资源数据报告不断地提供给连接到需要系统的所有资源。 以这样的方式提供关键资源的冗余，使得只有系统的发生故障的部分被禁用，同时系统的其余部分继续运行。
