摘要： A system for providing a cluster-wide system clock in a multi-tiered full graph (MTFG) interconnect architecture are provided. Heartbeat signals transmitted by each of the processor chips in the computing cluster are synchronized. Internal system clock signals are generated in each of the processor chips based on the synchronized heartbeat signals. As a result, the internal system clock signals of each of the processor chips are synchronized since the heartbeat signals, that are the basis for the internal system clock signals, are synchronized. Mechanisms are provided for performing such synchronization using direct couplings of processor chips within the same processor book, different processor books in the same supernode, and different processor books in different supernodes of the MTFG interconnect architecture.

摘要： A method and apparatus for handling, maintaining, and controlling network synchronization information emanating from a plurality of line card circuits is described. The technique described may be applied to a redundant pair of line card circuits, where one line card circuit is active, while the other is inactive. Line card activity latches are managed by means of hardware logic that may be configured at the time of line card commissioning. The activity latches are coupled to a logic element. An incoming clock signal is applied to the logic element. If an activity latch indicates that a line card circuit is active, the logic element provides the incoming clock signal as an outgoing clock signal to a control card circuit. If the activity latch indicates that the line card circuit is inactive, the logic element blocks the incoming clock signal from being passed and provides a static output level as the outgoing clock signal to the control card circuit. The control card circuit is provided with circuitry to receive the outgoing clock signals from multiple line card circuits. The circuitry is sensitive to whether or not the line card circuits are configured for redundant operation. One or more of these clock signals are then selected and used for network synchronization.

摘要： A communication device, such as a Voice over Internet Protocol (VoIP) gateway, determines a duration for Dual Tone Multi-Frequency (DTMF) tone portions of telephony signal. If the duration is less than a pre-determined amount, a minimum duration is enforced during DTMF playback at a remote end of a network connection connected to a destination gateway. Minimum playback duration can be enforced at the terminating gateway—however, the originatinggateway can also encode a DTMF packet with a minimum duration value. At the terminating receiver it is not always possible to playback exactly what happened at the originating point in the same time frame. One solution to is to, at the terminating gateway, drop the first portion of voice packets that overlap with the end portion of played back DTMF tones.

摘要： A plurality of metallic telephone lines carrying both baseband POTS (plain old telephone service) and DSL (digital subscriber line) or ADSL (asymmetric digital subscriber line) signals originate at customer premises and pass through a common field cabinet enroute to a telephone central office. Baseband POTS signals flow in an undisturbed manner through the field cabinet and maintain the normal, highly reliable, communication between the subscriber premises and the central office telephone switch. At the field cabinet, DSL/ADSL signals are removed from the metallic telephone line and are then communicated between the field cabinet and the central office using fiber optic broadband transmission. Fiber optic transmission increases the allowed distance between the ADSL transceiver located at the customer location and the respective ADSL transceiver located in the telephone central office. In the optical fiber, DSL and ADSL signals are retained in their 2B1Q, DMT, QAM or CAP analog format and are simply frequency translated in the process of frequency division multiplex (FDM) transmission. The arrangement allows the provision of ADSL service to customers beyond the distance limit normally imposed by a completely metallic telephone line. It is understood that this arrangement is equally applicable to a variety of DSL (digital subscriber line) signals.
摘要翻译：携带基带POTS（普通老式电话业务）和DSL（数字用户线路）或ADSL（非对称数字用户线路）信号的多条金属电话线路始发于客户驻地，并通过公共场地机柜通往电话中心局。基带POTS信号以不受干扰的方式通过现场柜流动，并保持用户驻地与中心局电话交换机之间的正常，高度可靠的通信。在现场机柜中，DSL / ADSL信号从金属电话线路中移除，然后使用光纤宽带传输在现场柜和中心局之间进行通信。光纤传输增加了位于客户位置的ADSL收发器与位于电话中心局的相应ADSL收发器之间的允许距离。在光纤中，DSL和ADSL信号保留在2B1Q，DMT，QAM或CAP模拟格式中，并且在频分复用（FDM）传输过程中简单地进行频率转换。该安排允许向超过通常由完全金属电话线施加的距离限制的客户提供ADSL服务。应当理解，这种布置同样适用于各种DSL（数字用户线路）信号。

摘要： A parallel cascaded set of transceivers using phase locked loops comprises a PCM communication link therebetween. At a first transceiver station, a primary framer receives an incoming signal. The primary framer extracts a payload signal and a clock signal and splits both. One clock signal is directed to the phase locked loop and the other clock signal is directed to a downstream transceiver. In this manner, start up delay and error introduction are reduced.

摘要： The invention discloses a method for multi-path TDM data transmission based on backplane and a TDM bridge connector for implementing the method. The method includes: applying a high-speed serial line on backplane to connect a center switch network board and service boards; multiplexing or interleaving multi-path TDM data at transmitting side, and then transmitting in batch to said high-speed serial line on the backplane; at receiving side, serial receiving said data and de-multiplexing or de-interleaving them to multiple TDM paths. The TDM bridge connector includes: a TDM high-speed serial transmitting adaptive circuit, a TDM high-speed serial receiving adaptive circuit and a clock control circuit. The invention increases greatly transmission capacity on backplane and looses the requirement of clock synchronization, so the system reliability is greatly raised.
