摘要： A Switch Fabric system comprising at least one Switch Fabric subsystem (100, 200) further including a set of Switch cores elements (111, 112, 121, 122) that are mounted in a port expansion permitting attachment of at least a first and second sets of Protocol Adapters (1, 2) under a routing control process. A Primary Switch controller (PSC) has a complete knowledge of the topology of the switch, e.g., the number of subsystems, the nature of the port expansion etc., while each Secondary Switch Controller only has a limited knowledge of that topology. One particular Switch Core (111, 211) which has a full-duplex communication capability in each Subsystem is assigned the key function to interface communication between the PSC and the other SSC in a same Switch Fabric Subsystem.

摘要： Network access apparatus includes a slave unit, including a plurality of subscriber ports adapted to be linked to respective subscriber lines, and a multiplexer for multiplexing among the ports. A master sub-system, is connected to at least one trunk line of a first public network, in a location remote from the slave unit. The master sub-system includes a first master unit, adapted to communicate with the slave unit via an assigned link through a second public network, so as to provide users of the subscriber lines with access to the first public network through the at least one trunk line. The master sub-system also includes a second master unit, coupled through the first master unit to communicate with the slave unit via the assigned link, so as to provide the users with access to the first public network through the at least one trunk line in the event of a failure associated with the first master unit.
摘要翻译：网络接入装置包括从单元，包括适于链接到各个用户线路的多个用户端口，以及用于多个端口之间复用的多路复用器。主子系统在远离从属单元的位置连接到第一公共网络的至少一条中继线。主子系统包括第一主单元，适于经由第二公共网络经由分配的链路与从单元通信，以便通过至少一个中继线为用户线路的用户提供对第一公共网络的访问线。主子系统还包括第二主单元，其通过第一主单元耦合，以经由分配的链路与从单元通信，以便通过至少一条中继线向用户提供对第一公共网络的访问与第一主单元相关联的故障的事件。
