# Decoder Parameters

The clear channel decoder component defined in the msp_FILTER_DECODER_PARMS structure supports only the following subset of parameters:

Field | Type | Default | Units | Description
size | DWORD | N/A | N/A | Size of the structure.
mode | WORD | 0x0001 (online) | N/A | Vocoding mode. Off-line means that the decoder filter plays silence to the DS0 endpoint. 0x0000 = off-line 0x0001 = online

All other parameters are ignored by the decoder.
