Embodiment Construction
[0011]FIG. 1 depicts a communication system 10 including the interconnection of 2G (second generation) network 20, such as an iDEN network coupled to a 3G (third generation) network 25 such as a CDMA network. Coupled to 2G network 20 is voice signaling gateway (VSGW) 30. Coupled between the voice signaling gateway 30 and 3G network 25 is a transcoder 40.
[0012] The transcoding function 40 has a set of 2G vocoders 43, 46-N. Further, transcoder 40 has a set of 3G vocoders 42 including vocoders 44, 47-M. Coupling the sets of vocoders 41 and 42 is a channel element control and switching 45. Conceptually, channel element and control and switching 45 interconnects a particular vocoder, for example vocoder 43 for coupling with 2G network 20 with a vocoder, for example vocoder 47, for coupling and translating with 3G network 25.
[0013] Within transcoder 40, channel element control and switching 45 basically selects a compatible vocoder to be compatible with the input being received from 2G ...
