Abstract: Embodiments of the present invention refer to a method for establishing a connection through a virtual private network “VPN” (9) between a first (1) and a second (3) entities of a transport network, the entities including a VPN interface (5, 7), wherein, between the interfaces, a bearer of a selected type, among a plurality of types corresponding to a plurality of quality of service “QoS”, is determined according to the QoS requested for the connection and wherein the parameters used by the VPN interfaces (5, 7) for the establishment of the bearer are global routing parameters corresponding to global routing parameters of the transport network and wherein the parameters include at least one parameter which is different from one bearer type to another so that the selected bearer type associated with the QoS requested for the connection is identified by the first and the second entities.

Abstract: In one embodiment, the method for rendering a music signal compatible with a discontinuous transmission codec includes detecting a period of silence within an initial music signal, producing an auxiliary audio signal whose amplitude is less than that of the initial signal outside of the period of silence, but sufficient to not be detectable as silence by a discontinuous transmission codec, and replacing the initial music signal with the auxiliary signal during the period of silence.
