摘要： A protocol for intra-shelf exchange of SONET/SDH line and path alarm, and section and line digital cross-connect information is disclosed. The protocol encompasses a method including continual monitoring each SONET/SDH datapath channel for alarms by one or more line cards (e.g., optical line interface, electrical line interface), processing the results of the channel monitoring to consolidate and encapsulate SONET/SDH alarm data by the line cards, forwarding this data to a switch card, which makes switching decisions based on the data. The SONET/SDH line, path, and equipment fault information may be collected, filtered, and prioritized by the line cards with some knowledge of the protection scheme(s) being implemented by the switch card, and may be formatted into an efficient encoding of the quality of each path. This path quality information for each path may be encapsulated into eight-bit byte subfields within a bit-serial, synchronous, 1215-byte framed protocol which is transmitted to the switch card out-of-band, i.e., without altering the SONET/SDH signal itself. The switch card takes advantage of this encoding by performing simple comparisons between path quality bytes from associated working and protect path pairs, and consequently burdening its microprocessor only when a protection switch is necessary.

摘要： A protocol for intra-shelf exchange of SONET/SDH line and path alarm, and section and line digital cross-connect information is disclosed. The protocol encompasses a method including continual monitoring each SONET/SDH datapath channel for alarms by one or more line cards (52), processing the results of the channel monitoring to consolidate and encapsulate SONET/SDH alarm data by the line cards (54), forwarding this data to a switch card (56), which makes switching decisions based on the data (58). The SONET/SDH line, path, and equipment fault information may be collected, filtered, and prioritized by the line cards with some knowledge of the protection scheme(s) being implemented by the switch card, and may be formatted into an efficient encoding of the quality of each path. The switch card takes advantage of this encoding by performing simple comparisons between path quality bytes from associated working and protect path pairs, and consequently burdening its microprocessor only when a protection switch is necessary.

摘要： The specification discloses methods and apparatus for selecting the better of two or more copies of a cell in a cell-oriented redundant switching system (107, 108) connected to an external communication network. In the preferred embodiment, the best cell copy selection (109) aligns redundantly transmitted cell streams before selecting cells for insertion in the data stream. Because the streams are aligned before the selection is made, the best cell copy selector compares each cell at the same instant in time, rather than basing its selection on past events.
摘要翻译：该说明书公开了用于在连接到外部通信网络的面向单元的冗余交换系统（107,108）中选择更好的两个或更多个小区副本的方法和装置。在优选实施例中，最佳小区复制选择（109）在选择用于插入数据流的小区之前对准冗余传输的小区流。因为在进行选择之前流是对齐的，所以最好的单元格复制选择器在时间上相同的时刻比较每个单元格，而不是将它们的选择基于过去的事件。
