NAME

       gsm_explode, gsm_implode — GSM 06.10 supplementary functions for testing

SYNOPSIS

       #include "gsm.h"

       void gsm_explode(g, frame, xframe)
       gsm        g;
       gsm_frame  frame;
       gsm_signal xframe[ 76 ];

       void gsm_implode(g, xframe, frame)
       gsm        g;
       gsm_signal xframe[ 76 ];
       gsm_frame  frame;

DESCRIPTION

       Gsm  is  an  implementation  of  the  final  draft GSM 06.10 standard for full-rate speech
       transcoding.  Test data for implementations of this particular document can be bought  and
       used to verify an implementation.

       The  encoded  test data uses a format different from what one would use to transmit frames
       with the least number of  bits.   Gsm_explode()  and  gsm_implode()  convert  between  the
       internal, small, 33-byte format and the 76-word format used by the test data.

RETURN VALUE

       gsm_explode() returns -1 if the passed frame is invalid, else 0.
