ABSTRACT:
The present invention switch transcoder (18) provides transcoding of speech for a cellular system in which speech from a plurality of E1 lines (7) may be compressed for outputting to a much smaller number of T1 lines (8) so that multiple conversations greater in number than previously possible can be carried on at the same time. The transcoding and switching of speech between the E1 and T1 lines are effected on a single module (30) which has thereon the control processor (42), voice processors (44) and appropriate interfaces (36, 40).
