ABSTRACT:
In order to improve a transcoder unit (TRCU) for use in a telecommunications network in such a way that digital voice signals can be transmitted at different transcoding rates, it is proposed to dispose at least two arithmetic units (FR, HR, EFR) with different transcoding rates on respective plug-in circuit boards in the transcoder unit, and to provide the transcoder unit with a subrack with backpanel wiring which receives these plug-in circuit boards. In this manner, arithmetic units each containing eight digital signal processors, for example, are provided for each of the different transcoding rates. The arithmetic unit can be optimized for each transcoding rate. Individual plug-in circuit boards can be replaced or added as supplements. The transcoder unit (TRCU) is modular in construction and can be assembled or converted very flexibly, e.g., in the manner of a backplane system. The transcoder unit is used, for example, in a wireless telecommunications network, i.e., in a mobile radio network.
