| 29 | .SH "DESCRIPTION" |
| 30 | Gsm is an implementation of the final draft GSM 06.10 |
| 31 | standard for full-rate speech transcoding. |
| 32 | Test data for implementations of this particular document |
| 33 | can be bought and used to verify an implementation. |
| 34 | .PP |
| 35 | The encoded test data uses a format different from what |
| 36 | one would use to transmit frames with the least number |
| 37 | of bits. |
| 38 | Gsm_explode() and gsm_implode() convert between the |
| 39 | internal, small, 33-byte format and the 76-word format |
| 40 | used by the test data. |
| 41 | .PP |
| 42 | .SH "RETURN VALUE" |
| 43 | gsm_explode() returns -1 if the passed frame is invalid, else 0. |
| 44 | .SH BUGS |
