A system, method, and computer program product are provided for reacting based on a frequency in which a compromised source communicates unsolicited electronic messages. In use, a source of at least two unsolicited electronic messages is identified as compromised. Additionally, a frequency in which the source communicated the unsolicited electronic messages is calculated. Furthermore, a reaction is performed based on the calculated frequency.

In accordance with illustrative embodiments, methods and apparati, which determine jitter are described. In one example embodiment, a method includes receiving a signal, wherein the signal comprises a first data pattern which was generated at a first bit rate. The method also includes sampling the signal at a second bit rate to generate a second data pattern. The period of the second bit rate is different from the period of the first bit rate. The method also includes comparing the first data pattern and the second data pattern to determine differences between the first data pattern and the second data pattern. Furthermore, the method includes determining jitter in the signal according to the differences between the first data pattern and the data second data pattern. In other embodiments, by using two different bit rates to determine jitter, jitter can be determined in communication systems in a convenient and cost effective manner.

Methods, systems, apparatuses, and computer program products for servicing advertisements for offline display on mobile devices are provided. In a first aspect, a channel is received at a mobile device server from one or more providers, including a first web page, an advertiser web page, and an advertisement image file. The received channel is transmitted to the mobile device. In an offline mode, when displayed, the first web page includes an image contained by the advertisement image file. A user viewing the first web page on the mobile device can select the displayed image of the advertisement image file to traverse a link to cause the advertiser page to be displayed on the mobile device. In another aspect, a plurality of advertisement image files are received and stored at a mobile device. The display of the advertisement images on a first web page is cycled each time the first web page is displayed on the mobile device.

A system and method for bit error rate testing optical components comprises providing an optical testing unit, which measures a bit error rate of an optical device under test (DUT) over an operating range of the DUT. The optical testing unit includes an optical transmitter, which transmits an optical test signal that is transmitted to the DUT; an optical receiver, which receives an input signal from the DUT; a graphical user interface, which provides an interface with a user; and a controller, selectively coupled to the transmitter, the receiver and the graphical user interface, wherein the controller provides a central control of the transmitter, the receiver and the graphical user interface.

An error analysis tester for an optical component includes an optical transmitter, an optical attenuator, a port, a receiver, a processor and a graphical display. The optical transmitter and optical attenuator produce a test signal at a plurality of selected optical power levels. The port is configured to output the test signal to the optical component and to receive a version of the test signal from the optical component. The receiver determines errors in the received version of the test signal. The processor determines data points of a function associated with an error rate at each of the selected power levels and a line corresponding to the data points. The graphical display produces a visual plot of the data points and the corresponding line.

An optical receiver is formed to include a digitally-controlled preamplifier that is used to adjust the bandwidth of the receiver. A measured bandwidth of the receiver is compared to a desired bandwidth and a digital control signal (such as a voltage, current, or any other appropriate parameter) supplied to the preamplifier is thereafter adjusted (either increased or decreased) to increase/decrease the bandwidth of the receiver to the desired value. A voltage regulator and potentiometer may be used as the digital controller and coupled to the input voltage supply of the preamplifier to provide the needed adjustment in voltage.
