摘要： A preconnectorized outdoor cable streamlines the deployment of optical waveguides into the last mile of an optical network. The preconnectorized outdoor cable includes a cable and at least one plug connector. The plug connector is attached to a first end of the cable, thereby connectorizing at least one optical waveguide. The cable has at least one optical waveguide, at least one tensile element, and a cable jacket. Various cable designs such as figure-eight or flat cables may be used with the plug connector. In preferred embodiments, the plug connector includes a crimp assembly having a crimp housing and a crimp band. The crimp housing has two half-shells being held together by the crimp band for securing the at least one tensile element. When fully assembled, the crimp housing fits into a shroud of the preconnectorized cable. The shroud aides in mating the preconnectorized cable with a complimentary receptacle.

摘要： A method and circuit for generating a signal to synchronize DQ data transfer in memory interface design is presented. The presented method includes receiving a strobe signal having a preamble period before and post-amble period after data transfer burst synchronization signal edge transitions, determining a timing location of the strobe signal preamble period, determining a timing location of the strobe signal post-amble period, and generating a clean strobe signal that tracks the data transfer burst synchronization edge transitions of the strobe signal after the strobe signal preamble begins and before the strobe signal post-amble ends based on the respective determined timing locations of the strobe signal preamble and post-amble periods. In this manner, DQ data transfer may be synchronized according to the burst synchronization signal edge transitions and errors caused by strobe signal level jitter during the preamble and post-amble periods are reduced.

摘要： A method and apparatus utilizing historical network information for mitigating excessive network updates when performing channel selection between a serving base transceiver station and an adjacent base transceiver station when determined channel selection would result in either a Location Area Update (LAU) or a Routing Area Update (RAU) is presented. If a network update, either LAU or RAU, is the first occurrence, network identification information for the LA or RA is stored and an incremental value indicating occurrence is set; else in the case occurrence is not the first, the incremental value is incremented. A first margin value is then selected if the incremented value does not meet or exceed a predetermined value, or a second margin value is selected if the incremented value does meet or exceed a predetermined value. The signal level of the adjacent base transceiver station is then compared to the reference signal level of the serving base transceiver station plus the selected margin value in order to determine channel selection.

摘要： Adaptive acknowledgement delay entails adaptively adjusting an acknowledgement delay period responsive to channel quality. A destination device is enabled to set the acknowledgment delay period between two successive acknowledgments that acknowledge blocks received from a source device over a wireless channel. In a described implementation, the acknowledgment delay period is decreased if the wireless channel quality is poor. Otherwise, the acknowledgment delay period is increased as bounded by a maximum acknowledgment delay period setting and a remaining number of unreceived blocks of a current suprablock. The quality of the wireless channel may be reflected by, for example, blocks that are received erroneously. The duration of the acknowledgment delay may be set in terms of number of blocks received at the destination device.

摘要： Disclosed are methods that enable communications to be established regardless of the presence of communications blockers, e.g., firewalls and NATs, in the path between two computing devices. Two devices each establish communications with a rendezvous service. Through the service, the devices signal each other to set up direct, peer-to-peer communications between themselves. If the devices fail to establish direct communications, then they invoke a relay service that provides the illusion of direct communications. In another aspect, an originating device attempts to establish communications with a recipient, using an address and port number associated with the recipient. If that attempts fails, possibly because a firewall is blocking communications, then the originating device retries using a port normally held open by firewalls. If this attempt also fails, then the originating device invokes the services of a proxy to negotiate a port acceptable for use by the recipient and by any intervening firewalls.
摘要翻译：公开了能够建立通信的方法，而不管在两个计算设备之间的路径中是否存在通信阻塞器，例如防火墙和NAT。两个设备各自建立与会合服务的通信。通过服务，设备相互信号，建立起彼此直接的对等通信。如果设备无法建立直接通信，则调用中继服务，提供直接通信的错觉。在另一方面，始发设备尝试使用与接收者相关联的地址和端口号与接收者建立通信。如果尝试失败，可能是因为防火墙阻止通信，则始发设备将使用通常由防火墙打开的端口重试。如果此尝试也失败，则始发设备调用代理服务以协商一个可接受的端口以供任何中间的防火墙使用。
