  • Patent number: 4887261
    Abstract: A method and arrangement for transmitting a digital signal with a low bit rate in a time section, provided for higher bit rates, of a time division multiplexed signal. At a transmitting end the first digital signal with a low bit rate is over-sampled with a first clock signal assigned to this time section. A second digital signal which results is transmitted in the time division multiplexed signal to a receiving end. Following the demultiplexing of the time division multiplexed signal, this second digital signal is sampled with a second clock signal, corresponding to its bit rate, omitting forbidden phase position zones, and results in a fifth digital signal. The forbidden phase position zones are defined by a shift register, an exclusive-NOR-gate, an upwards/downwards counter and a logic unit. Double samplings are prevented in that the phase of the second clock signal is shifted via the resetting of a frequency divider.
