摘要： A network interface card (NIC) (20) using PPP (point to point protocol) with multiple dial up channels implements a state machine, e.g., with a field programmable gate array and a microprocessor (28), to perform "bonding" or inverse multiplexing of multichannel ISDN connections and to encapsulate data for transmission or reformat received data as HDLC frames, allowing a host or client running RAS to effect PPP communications with high bandwidth. The NIC includes a controller and a plurality of buffers, each storing data from a respective channel. The NIC generates reordering pointers for each of the plurality of buffers based on training data to reflect offsets or differences in frame count and interchannel delays in the data.

摘要： A method and apparatus are provided for permitting all forms of traffic on a telephone system (10), including various forms of data traffic, to be handled without resulting in a significant degradation in service to customers (14, 16, 18, 20, 48), while facilitating the controlled growth of the telephone system (10) to handle rapidly increasing classes and levels of traffic. This is accomplished by providing one or more bypass networks (84) in such a system, with at least one class of traffic being bypassed through such bypass network (84) so as to not be passed through and utilize shared system resources. A control unit (60) for use in such a bypass network (84) architecture is also provided.

摘要： Improved ISDN interface apparatus (10) and methods permit dual mode access to an on-board memory (36). A first memory controller (38) is provided that responds to addresses in a first address range to read, write or otherwrite access data in an "on-board" memory (36) a first memory access mode. A second memory controller (40) is provided that responds to addresses in a second address range to access data to that memory (36) in a second memory access mode. Multiplexing circuitry (42) selectively applies control signals from the first or second memory controllers (38 or 40) to the memory (36), thereby, causing it to read, write or otherwise access data according to the first or second modes. The aforementioned first and second modes can constitute differing memory access modes. Thus, for example, first mode is a single-beat memory access mode, according to one practice of the invention. The second mode can comprise, on the other hand, for example, a burst mode.
摘要翻译：改进的ISDN接口装置（10）和方法允许双模式访问板载存储器（36）。提供了第一存储器控制器（38），其响应于第一存储器访问模式中的“板上”存储器（36）中的第一地址范围中的地址读取，写入或其他写入访问数据。提供了第二存储器控制器（40），其响应第二地址范围中的地址以在第二存储器访问模式下访问到该存储器（36）的数据。多路复用电路（42）有选择地将来自第一或第二存储器控制器（38或40）的控制信号施加到存储器（36），从而使其根据第一或第二模式读取，写入或以其他方式存取数据。上述第一和第二模式可以构成不同的存储器访问模式。因此，例如，根据本发明的一个实践，第一模式是单节拍存储器存取模式。另一方面，第二模式可以包括例如突发模式。

摘要： A system for transmitting compressed data for multiple channels or contexts from a single node which system reduces memory utilization without significant adverse effect on compression ratio by providing a separate history buffer for each channel, with a single hash table being provided for generating potential match addresses in the history buffer for at least selected ones of the channels. A single chain table may also be provided, the chain table having a single offset address for the corresponding offset addresses in the buffers for the selected channels. Collisions in the common hash table may be reduced by including channel address or the like as an additional input to the hash table, thereby biasing the address outputs therefrom.

摘要： Apparatus and method for compression of a digital sequence. The compressed sequence may be buffered and a compression procedure altered depending on buffer usage. This altering may include changing the depth of searching for matches performed in linked lists depending on the amount of the sequence being buffered. An adjacent element can be found in a linked list using a pointer, and a match can also be found in a history buffer using the same pointer. Frequency values may be updated for symbols based on a sampled subset of the symbols, and a token may be derived, such as by Huffman encoding, for each symbol from the updated frequency values. A subsequence may be encoded using an offset referenced to an earlier match. An insert pointer and a check pointer into a history buffer may be maintained, and a determination can be made as to whether accessing the history buffer is valid based on these check pointers. The maximum amount of the history buffer in which accessing is valid may be set. Decompression of sequences is also presented.

摘要： A system having multiple identical modules which is capable of operating in a plurality of fault tolerant modes. A single module may be designated as a protection module for n application modules with the I/O terminals (209) for a module being routed through switches of another module and a protection bus where required to the protection module if the given module fails. In 1x1 mode, a protection module is provided for each application module with the I/O terminals (209) of the application module being connected to the protection module through switches in the protection module. Mixed modes of operation are also possible where some application modules are connected in 1:n mode while one or more other application modules are connected in 1x1 mode. Switches or other connecting elements (216, 217, 223) may be provided to permit the protection mode for a given system to be easily altered without requiring any wiring changes.
