Abstract:
1. A method that comprises: defining a transmission schedule of a TDM data frame that comprises multiple TDM time slots allocated for transmitting data over a TDM line; 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 to a fullness level of the first intermediate storage unit and to the transmission schedule; and providing, in response to the transmission schedule, a stabilized data segment from the first or the second intermediate storage units to a transmission storage unit and transmitting the data segment from the transmission storage unit over the TDM line.
