Abstract: A device having frame receiving and processing capabilities and a method for receiving and processing frames. The method includes: receiving a frame; associating a frame timestamp with the frame; storing the frame and the associated timestamp at a certain buffer out of a group of buffers; generating a valid timing information frame indicator if the received frame is a valid timing information frame; and storing the valid timing information frame indicator at a certain buffer descriptor associated with the certain buffer.

Abstract: A device and a method. The device includes: (i) a processor, connected to the receiver, (ii) an interface adapted to receive a test vector and to output a test response, the test vector includes a first group of signals that include idle signals and at least one information frame and a second group of signals that include timing signals and data signals; and (iii) a receiver, connected to the interface. The receiver is adapted to receive the first group of signals and filter out the idle signals and at least one instruction frame delimiters to provide at least one instruction. The device is adapted to send the at least one instruction to at least one instruction buffer. The processor is adapted to execute at least one instruction stored in the at least one instruction buffer and to respond to the second group of signals such as to provide test responses.

Abstract: A method for transmitting data, the method includes scanning at least a first memory unit to retrieve data segments associated with multiple TDM channels, in response to a definition of multiple TDM time frames, each TDM time frame includes multiple time slots; sending the retrieved data segments to an array of line shifters; multiplexing data segments provided from the array of line shifters, in response to the definition, such as to provide in a parallel manner multiple data segments to multiple TDM lines; and transmitting a group of time division multiples data frames over a group of TDM lines.

Abstract: A method for managing under-runs and a device having under-run management capabilities. The method includes retrieving packets from multiple buffers, monitoring a state of a multiple buffers, determining whether an under-run associated with a transmission attempt of a certain information frame from a certain buffer occurs; if an under-run occurs, requesting a certain information frame transmitter to transmit predefined packets while ignoring packets that are retrieved from the certain buffer, until a last packet of the information frame is retrieved from the certain buffer; and notifying a processor that an under-run occurred after at least one predefined packet was transmitted; wherein each buffer out of the multiple buffers is adapted to store a fraction of a maximal sized information frame.

Abstract: A method that includes defining a transmission schedule of a TDM data frame that includes multiple TDM time slots allocated for transmitting data over a TDM line; the method is characterized by including: providing a transmission clock signal having a transmission clock frequency to the TDM line, providing a first clock signal having a first clock frequency to data sources that belong to a first group of data sources and providing a second clock signal having a second clock frequency to data sources that belong to a second group of data sources; wherein the first clock frequency and the second clock frequency are higher than the transmission clock frequency; pre-fetching, to a first intermediate storage a data segment from a data source out of the first group of data sources in response to a fullness level of the first intermediate storage unit and to the transmission schedule; pre-fetching, to a second intermediate storage a data segment from a data source out of the second group of data sources in response
