摘要： Systems and methods provide analog delay elements, which may be utilized in isolation or in a cascade, such as for use within equalizers or other types of applications. For example, a delay element may include a broadband amplifier and a passive, programmable filter, which may provide a desired magnitude and group delay response over a wide frequency range while being tolerant of process variations. An equalizer, for example, may include the delay element within its feed forward filter and/or within its other circuits, such as within its adaptive coefficient generator or slicer input time-align circuit.

摘要： Disclosed are systems and methods for providing ring back tones in a communication network. At first, a ring back tone device for storing and playing the ring back tone customized by a subscriber is established in the communication network. Whether a subscriber is a ring back tone service register subscriber is judged with a certain triggering mode, such as intelligent network triggering, signaling interception triggering, call forwarding triggering or switching device triggering. If it is judged the subscriber is a ring back tone service registered subscriber, a connection between the originating switching device and the terminating switching device and a connection between a switching device and the ring back tone device are established. When the called terminal is idle, the ring back tone device provides a piece of customized ring back tone to the calling subscriber for replacing traditional ring back tone.

摘要： Fractional or fuzzy time stamp values are used during processing network traffic. Handling fractional time stamp values permits scaling down of time stamp values, so that fewer bits, and memory, are needed to store each fractional time stamp value. According to a specific technique, departure times are set based on a quantity X plus Y/Z, where X is an integer, Y is a numerator, and Z is a denominator. The departure times are synchronized with the ideal departure times after (Z*X+Y) time units. A technique is provided to reduce cell delay variation.
