摘要： An N+1 sparing strategy for both line circuits and switching nodes of a self-routing 3-stage Benes packet telecommunications network. Line circuits selectively serve either their own telecommunications line or the line normally served by the corresponding line circuit of the preceding row of the switching matrix. A row of spare line circuits and switching nodes is provided. Upon failure of a matrix internal node, line circuits modify packet addresses to reroute packets normally served by the failed node, or nodes below it within the same switching stage, to the next-lower row. Upon failure of a matrix edge node, line circuits of the failed node's row are disabled and line circuits of each row below it commence to serve the lines normally served by the preceding row. Active line circuits also modify packet addresses to reroute packets normally served by the last-stage node of the failed node's row, or rows below it, to the next-lower row. Upon failure of a line circuit, it is disabled and corresponding line circuits of each row below it commence to serve the lines normally served by the corresponding line circuit of the preceding row. Active line circuits also modify packet addresses to reroute packets normally switched to the failed line circuit or to the corresponding line circuits of the rows below it, to the corresponding line circuit of the next lower row.

摘要： A process that disallows any bridging onto the signal to be broadcast from any switch of the input stage of the Clos switching network and that further disallows any requests for point-to-multipoint broadcast connections in excess of the number of switches in the center stage of the network avoids the perceived problems with maintaining point-to-multipoint broadcast connections in a Clos switching network. Such a process causes rearranging to occur only when the broadcast connection is established or added to. It also guarantees that paths for point-to-point connections can always be found, when they are requested, without spending time to rearrange any other connection.
摘要翻译：一种过程，不允许任何桥接到要从Clos交换网络的输入级的任何交换机广播的信号，并且进一步禁止对点到多点广播连接的任何请求超过中心阶段的交换机的数量网络避免了在Clos交换网络中维护点对多点广播连接的感觉到的问题。这样的过程导致只有当建立或添加广播连接时才进行重新排列。它还保证了点对点连接的路径始终可以在被请求的时候找到，而不用花时间重新安排任何其他连接。

The improved switch includes a test access system in which selected input or output lines of the cross-connect switch are utilized as test ports. The switch utilizes computer algorithms to make connections between a test port and one of the switch modules through which a path connecting specified input and output lines passes to make a bridging connection to the path.

摘要： A Layered Network system may provide varying cost from order NlogN low-cost networds, to completely-routing, fully-Layered networks with cots of order Nlog .sup.3 N. Layered networks are composed of switches and point-to-point connections between them. These networks establish connections from requestors to responders by relaying "requests" through the switches. Each switch has built-in control logic to route requests and responses. The switch setting is determined using the comparison of the request with the request's current location in the network, and with locally competing requests. To provide distributed routing without a centralized controller, each switch routes the requests using only the information contained in the requests that switch handles. The switch setting is remembered in order to route the responses on the same paths as the associated requests, but in the reverse direction.
摘要翻译：分层网络系统可以提供从NlogN订单低成本网络到完全路由的完全分层网络，具有Nlog 3N订单的成本。分层网络由交换机和它们之间的点对点连接组成。这些网络通过交换机中继“请求”来建立从请求者到响应者的连接。每个交换机都有内置的控制逻辑来路由请求和响应。交换机设置是使用请求与请求在网络中当前位置的比较以及本地竞争的请求来确定的。为了提供没有集中控制器的分布式路由，每个交换机只使用交换机处理的请求中包含的信息来路由请求。记住切换设置，以便在与相关请求相同的路径上路由响应，但是反向。

摘要： A serial switched interconnection network comprises several stages of switching units each having a plurality of source ports and destination ports interconnected so that any source port of the first stage can be connected to any destination port of the final stage by operation of switching units in successive stages. Connections are by shared data and control paths each of which paths may comprise a single line or multiple lines and each switching unit when switched to along a path sends a request back up that path for sufficient data signals to operate the switching unit initiating the request. The setting up of a path through the network is thus stage-by-stage asynchronously.
摘要翻译：串行交换互连网络包括若干阶段的交换单元，每个交换单元具有互连的多个源端口和目的端口，使得第一级的任何源端口可以连续地通过开关单元的操作连接到最终级的任何目的地端口。连接是通过共享数据和控制路径，每个路径可以包括单个线路或多条线路，并且每个交换单元在沿着路径切换时发送请求备份该路径以便足够的数据信号来操作开始请求的交换单元。因此，通过网络建立一条路径是异步的。

摘要： An arrangement and method for interconnecting the stages of a space division switching network which provides simple and continuous growth from a small number of lines to the system's maximum number of lines. The switching network comprises up to M input stage switches, center stage switches and up to M output stage switches. Incoming lines are connected to the input terminals of the input stage switches such that no input stage switch is connected to a number of incoming lines which exceeds the number of incoming lines connected to any other input stage switch by more than one. The number of center stage switches is established from a predetermined interconnection plan and at any given time, the number of center stage switches is a function of the number of lines connected to the input stage switch having the largest number of lines connected thereto. As each line is connected to an input stage switch, the output terminals of that switch are distributed over the available center stage switches. The output stage switches are connected to the center stage switches and to outgoing lines in analogous manner.

摘要： There is disclosed a communication system arrangement whereby the efficiency with which pooled facilities are used can be increased by reducing the number of lines that are dedicated to the pool. This is accomplished by making available to the pool, on a priority basis, lines that have been installed for other purposes, such as, for example, conference lines and private two-way lines. The system is arranged such that dedicated pooled lines have a higher priority than other lines which are available to the pool on a decreasing priority basis. In addition, each pooled set of lines at each station is given a visual indication using the system available lamp to indicate whether an idle line remains in the pool. This arrangement allows each station user to determine, without unnecessary seizure attempts, whether or not an available line exists in the pool.
