GSM_EXPLODE 3
NAME
gsm_explode, gsm_implode \(em 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.
