    • Eye violation detectors which provide either one of a "graded" or "half-graded" eye violation indicator technique. More particularly, the eye violation detector for practicing the "graded" technique provides an eye violation region in one or more eyes of a multiple eye pattern which is uniformly disposed on either side of the center of each of one or more eyes of the multiple pattern and includes a different amplitude in each of the eye patterns of interest. The eye violation detector for practicing the "half-graded" technique provides an eye violation region in one or more eyes of a multiple eye pattern which is disposed on only one side of the center of each of one or more eyes, except for the center eye of the multiple eye pattern, and includes a different amplitude in each of the eye patterns of interest.

    • A system provides automatic protection switching in case of failure or degradation in a function. For example, a system node may have a working server function, a protection server function, one or more client functions, and a control function. In its baseline configuration, the working server function is active, meaning that it is operating on-line with respect to the client functions, while the protection server function is standby, meaning that it is either inactive (i.e., cold standby) or operating off-line with respect to the client functions (i.e., hot standby). The control function monitors the operations of the working server function, and, if a failure or degradation is detected, or if an externally generated switch command is received, the control function will (1) instruct the working server function to change its status from active to standby and (2) instruct the protection server function to change its status from standby to active. In addition, the control function instructs each server function about a protection switch override condition. Each server function communicates its active/standby status as well as the override condition to the client functions (e.g., using in-band signaling). In addition to monitoring the active/standby status and the override condition transmitted from each server function, each client function also performs its own independent monitoring of the status of the server functions to detect failures or other degradation in the server functions. Each client function then applies a specific set of rules to this information to determine which server function to select for its operations. The set of rules are designed to handle race conditions and other ambiguous states.
    • 系统在功能故障或退化的情况下提供自动保护切换。 例如,系统节点可以具有工作服务器功能,保护服务器功能,一个或多个客户机功能和控制功能。 在其基线配置中,工作服务器功能是活动的,这意味着它在客户端功能上在线运行,而保护服务器功能处于待机状态,这意味着它处于非活动状态(即冷备用)或运行 - 关于客户端功能(即热备份)。 控制功能监控工作服务器功能的操作,如果检测到故障或劣化,或者接收到外部生成的开关命令,则控制功能将(1)指示工作服务器功能将其状态从活动状态改变 待机,(2)指示保护服务器功能将其状态从待机状态更改为活动状态。 此外,控制功能指示每个服务器功能关于保护开关覆盖条件。 每个服务器功能将其主动/待机状态以及覆盖条件传达给客户端功能(例如,使用带内信令)。 除了监视主动/待机状态和从每个服务器功能发送的覆盖条件之外,每个客户端功能还执行其自身对服务器功能的状态的独立监视,以检测服务器功能中的故障或其他劣化。 然后,每个客户端功能都将特定的一组规则应用于此信息,以确定为其操作选择哪个服务器功能。 这套规则旨在处理种族条件和其他模糊状态。

    • A test system for a evaluating a digital signal link includes a data signal generator, a data signal receiver, a digital signal link to be tested and a test interference signal injection (TISI) network connected as part of the digital signal link. The TISI network includes a data signal input port for receiving digital data signals generated by the data signal generator, a data signal output port for providing the digital data signals to the data signal receiver, and a controlled impedance data signal path carrying the digital data signals between the data signal input port and the data signal output port. An interference signal input port receives interference signals over a range of frequencies from an interference signal generator. One or more directional couplers directionally couple the interference signals into the data signal path toward either the data signal output port or the data signal input port at an impedance that substantially matches the impedance of the digital signal link. The directional couplers are configured to maintain d.c. isolation from ground to facilitate the transfer of d.c. coupled data signal logic through the TISI network.

    • Separate components of a received signal are transmitted along two distinct paths to the adaptive cross-polarization interference cancellation arrangement. In each path, appropriate circuitry obtains a sample of a desired component in a particular signal, generates a signal representative of the power envelope of the sample, detects the in-phase and quadrature signals of a correlation between the desired component and interference, and generates control signals in response to the correlation signals to provide improved adjustment of the amplitude and phase of the interference in a canceler circuit. Each path includes a single square law device to reduce DC offset in correlation measurements which occur from square law device mismatches.

    • The present invention relates to an adaptive cross-polarization cancellation arrangement where a first desired polarized signal and a second interfering orthogonally polarized signal, including cross-polarization components, are concurrently received at an antenna. In the present arrangement, the orthogonally polarized components of the received signal are separated and transmitted along separate paths and recombined after the phase and amplitude of the separated polarized interfering signal sample has been appropriately adjusted for maximally cancelling cross-polarization components thereof in the other path. A feedback path includes circuitry for obtaining a sample of any remaining interfering signal in the recombined output signal, generating a signal representative of the power envelope of such sample, and then generating appropriate control signals in response to such representative power envelope signal to provide improved adjustment of the amplitude and phase of the separated polarized interfering signal sample.
