摘要： A multistage ATM switch, method and system with switch elements with two input/outputs switchable to two other input/outputs. The switch elements are arranged connected to define a matrix with an input stage an output stage and at least one an intermediate stage. The multi stage switch inputs are presented with address information for data, the address information indicates requests for one of several outputs of said the multi stage switch. The requests are broadcast into the multi stage switch. At each stage the requests are remembered, merged and propagated to connected switching elements of a next stage. At each output of the multi stage switch grants a request if traffic can be accepted and propagates the requested grant to connected switching elements. At each switching element, upon receiving a request grant, the request grant is propagated to an input that requested the granted output port. If both inputs requested the granted port the switch element randomly chooses one of the two inputs and propagates the grant on the randomly chosen input. Upon receiving a request grant at an input of the multi stage switch, data is transmitted on a next time slot.

摘要： A conductive panel adapted to align and retain a printed circuit board modular device carrier assembly. The assembly includes a printed circuit board and a plurality of modular electronic device carriers, each sized to slidably receive a modular electronic device such as a Gigabit Interface Converter. The panel includes at least two generally rectangular openings oriented in a row of opening. The openings are sized to permit the modular electronic device to be slidably disposed therethrough. At least one inwardly extending conductive finger is provided integral with the panel and generally orthogonal to the inner panel surface adjacent the bottom edge of the opening and at least one inwardly extending finger is provided integral with the panel generally orthogonal to the inner panel surface adjacent the upper edge of the opening. The upper and lower fingers securely retain the printed circuit board carrier assembly therebetween when the carrier assembly and panel are in assembled relation. Conductive ground contacts are selectively positioned on one side of the printed circuit board. The lower fingers abut the contacts so as to electrically couple the conductive panel to ground through the ground contacts.

摘要： In a Local Area Network (LAN) system, an ethernet adapter exchanges data with a host through programmed I/O (PIO) and FIFO buffers. The receive PIO employs a DMA ring buffer backup so incoming packets can be copied directly into host memory when the PIO FIFO buffer is full. The adapter may be programmed to generate early receive interrupts when only a portion of a packet has been received from the network, so as to decrease latency. The adapter may also be programmed to generate a second early interrupt so that the copying of a large packet to the host may overlap reception of the packet end. The adapter to begin packet transmission before the packet is completely transferred from the host to the adapter, which further reduces latency. The minimal latency of the adapter allows it to employ receive and transmit FIFO buffers which are small enough to be contained within RAM internal to an Application Specific Integrated Circuit (ASIC) containing the transceiver, ethernet controller, FIFO control circuitry and the host interface as well.
摘要翻译：在局域网（LAN）系统中，以太网适配器通过编程I / O（PIO）和FIFO缓冲器与主机交换数据。接收PIO采用DMA环形缓冲区备份，因此当PIO FIFO缓冲区已满时，传入的数据包可以直接复制到主机存储器中。当只有一部分分组已经从网络接收到时，适配器可以被编程为产生早期接收中断，以便减少等待时间。适配器也可以被编程为产生第二早期中断，使得将大数据包复制到主机可能重叠接收分组端。在数据包完全从主机传输到适配器之前，适配器开始分组传输，这进一步减少了延迟。适配器的最小延迟允许其使用足够小的接收和发送FIFO缓冲器，以将其包含在包含收发器，以太网控制器，FIFO控制电路和主机接口的专用集成电路（ASIC）内部的RAM内部。

摘要： A method and apparatus for receiving and transmitting network frames via an internetworking device, in which a first portion of a total number of buffers is allocated among port-dedicated buffer pools, and a second portion is placed in a common pool accessible by any of the network ports. A frame is received at a first port, and a list of buffers accessible only by that port is referenced to identify buffers not already in use. A second list of buffers in the common pool is referenced to identify unused buffers for use if insufficient unused buffer space is available in the port-dedicated buffer pool. Frame data is then stored in the identified buffer(s). Upon retransmission, the buffer(s) used to store the. transmitted frame is released to the port-dedicated and/or common buffer pool(s).

摘要： Method for improved configuration of a link between an end station and an intermediate device in a network. The intermediate device communicates through the link using a point-to-point protocol, and a lower layer protocol and is capable of translating between the lower layer protocol used by the link and a lower layer protocol used by a portion of the network. The intermediate device detects the lower layer protocol used by the end station and configures the link to use the point-to-point protocol, the lower layer protocol used by the end station, and an asymmetric digital subscriber line (ADSL) protocol. A method including signaling the end station to use on the link a lower layer protocol having a particular relationship with the lower layer protocol used by the portion of the network. The particular relationship, according to an aspect of the invention, is that the protocol that the end station is signaled to use is the same as the protocol used by the portion of the network thereby creating efficiencies in transmission from the end station through the intermediate device onto the network.

摘要： Apparatus, and accompanying methods for use therein, for an ISDN LAN modem (300) (and various aspects thereof) that is particularly, though not exclusively, suited for small user environments and which contains an internal ISDN router (305) having a self-contained network hub (340) for inter-connecting multiple network devices, such as workstations (10), to each other through a local area network (LAN) and for permitting each of those devices to each gain access through the router to any one of a number of different remote networks. Advantageously, to facilitate and simplify its configuration, the LAN modem automatically adapts itself to a current network environment of a workstation connected thereto, via the LAN, and then communicates with that workstation through a browser executing thereat to obtain configuration information from a user situated at the workstation. Additionally, the LAN modem, through use of a multi-tiered routing hierarchy including both destination- and source-based routing, accommodates several modalities of network communication not heretofore possible in a conventional router. Specifically, several different workstations can simultaneously communicate through the LAN modem with a common remote network (60) and share a single user account at a corresponding network service provider.

摘要： A self-starting brushless electric motor having: a first motor part (stator) (11) with poles (15S, 16A) arranged in a first pole row, said poles comprising for each winding phase a pole group (13) including a pole pair consisting of a reluctance pole (15S) and a permanent-magnet pole (16A), only one such pole group being provided for each winding phase; a second motor part (rotor) (12) movable with respect to the first motor part (11) and provided with reluctance poles (18A) arranged in a second row of poles opposite to the first row of poles; and a magnetizing winding (17) on the first motor part (11). At least one of the pole rows exhibits a magnetic asymmetry providing a preferential relative direction of movement of the motor parts (11, 12) upon energization of the winding. The poles (15S, 16A) of the pole pair of the first pole row are spaced-apart such that whenever a pole of the pair is magnetically aligned with a pole (18A) of the second pole row, the other pole of the pair is magnetically misaligned with the next adjacent pole of the second pole row. A ferromagnetic auxiliary pole means (20) is provided on the first motor part (11) and positioned such that whenever the permanent-magnet pole (16A) of said pair is magnetically aligned with a pole (18A) of the second pole row, the auxiliary pole means (20) confronts at least one of the other poles of the second pole row across an air gap (19) which separates the pole rows.

摘要： A sliding door mechanism for a portable communication or data processing device is adapted for placement of the device on a docking port. The portable device has a component that is covered by the sliding door when the door is in a closed position. A single wire spring coupled with the door and the device has a spring force tending to keep the door closed. The door opens in response to placement of the device on the docking port rail. Upon placement of the device on the docking port rail, the docking port rail slides into guides on a door receptacle located on the housing of the device. The rails of the door in the closed position are slidably disposed in the door receptacle guides. The weight of the device causes the door receptacle guides to cover the docking port rail. As the door receptacle guides slide onto the docking port rail, the door rail is moved upwards into the device, the spring is compressed and the door opens. When the door is in the open position, the docking port connector is in contact with a device component so that the device can communicate through the docking port to other data processing and communication devices. Also, because of the weight of the device supported by the docking port, and the spring force, the device connection to the docking port has very little wobble.
