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.

Please direct bug reports to jutta@pobox.com and cabo@tzi.org.
