.SH "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.
|
|
.PP
|
|
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.
|
|
.PP
|
|
.SH "RETURN VALUE"
|
|
gsm_explode() returns -1 if the passed frame is invalid, else 0.
|
|
.SH BUGS
