摘要： A data scrambler, which transmits a data sequence, includes circuitry to suppress consecutive occurrences of a predetermined number of data sequence bits having the same value. The number of consecutive occurrences of bits having the same value are counted. When the number of consecutive occurrences of bits having the same value reaches a predetermined number, at least one of the bits of the transmitted data sequence is inverted. Complementary circuitry is included in a data descrambler so that the bits that were inverted by the data scrambler can be re-inverted to their original value by the descrambler.

摘要： A subscriber loop remote control apparatus that allows communication terminals to transmit VLAN packets without imposing a load on a router. A subscriber loop remote control apparatus is provided with a virtual interface table for associating a subscriber premises terminal identifier individually assigned to a subscriber premises terminal connected through a communication cable to a port assigned to every packet of each group which constitutes a VLAN with the port number of the port to store and manage them. When receiving a packet, the subscriber loop remote control apparatus determines whether or not a subscriber premises terminal identifier contained in the packet matches any of those in the virtual interface table. When the subscriber premises terminal identifier matches one of those in the virtual interface table, the subscriber loop remote control apparatus returns and transmits the packet to the destination before the router side.

摘要： In a self-healing network, virtual paths between user terminals are classified according to different fault recovery priority levels and communication links are mapped to virtual paths accommodated by the links and to bandwidths remaining in the respective links. Each priority level guarantees a fault recovery with a different amount of network resource. In response to a fault-indicating message identifying a failed virtual path, a search is made through the link-path table for an alternate virtual path and a remaining bandwidth of each link that comprises the alternate virtual path in descending order of the priority classes. In accordance with the priority class of the failed virtual path relative to the priority class of an existing virtual path that shares the same link with the alternate virtual path, a decision is made on whether or not the bandwidth guaranteed by the priority class of the failed virtual path can be allocated to the alternate virtual path from the remaining bandwidth. If the decision is affirmative, the alternate virtual path is established.
摘要翻译：在自愈网络中，根据不同的故障恢复优先级对用户终端之间的虚拟路径进行分类，并将通信链路映射到由链路容纳的虚拟路径和相应链路中剩余的带宽。每个优先级保证使用不同数量的网络资源进行故障恢复。响应于识别故障虚拟路径的故障指示消息，通过链路路径表针对替代虚拟路径进行搜索，并且以优先级等级的降序包括包括备用虚拟路径的每个链路的剩余带宽。根据与备用虚拟路径共享相同链路的现有虚拟路径的优先级相对于故障虚拟路径的优先级，决定是否由优先级别保证失败的带宽虚拟路径可以从剩余带宽分配给备用虚拟路径。如果决定是肯定的，则建立备用虚拟路径。

摘要： In a cross connecting network wherein a branching device branches a group of digital signals into duplexed groups for supply to two switch matrix devices, each including switch elements in foremost through last stages, at least three in number, to cross switch the digital signals through cross connected paths with a switch request flag superposed on each digital signal downstream of a defective element of the switch elements and wherein a redundancy switching device detects the flag to make a control device control the switch elements of the last stage selectively connect the cross connected paths of the switch matrix devices path by path to switching device paths, a monitor is used in the cross connected paths of each switch matrix device before each switch element of the second through the last stages to detect a monitor datum sent thereto together with each digital signal to locate the defective element, and to assist the control device in path by path selecting the cross connected paths of each switch matrix device. The switch elements may be grouped into switch units. Preferably, a like monitor is connected to each switching device path to detect if each switch element of the last stage is defective. More preferably, an indicator is connected to the monitor to indicate the defective element.
