DSP.C5x[x].XLaw

Determines the DSP hardware companding mode.

Syntax

DSP.C5x[x].XLaw = mode

x = 0-(n-1) (A range of DSP cores where n equals the total number of DSP cores available.)

Access

Read/Write

Type

String

Default

A_LAW

Allowed values

A_LAW | MU_LAW | NO_LAW

Example

DSP.C5x[0..31].XLaw = MU_LAW

Details

For A_LAW and MU_LAW modes, 8 bit data sent and received to or from the HMIC circuit switch is converted to or from the 16-bit linear form used internally.

NO_LAW uses bits 0 - 7 of the 16-bit word for the 8-bit timeslot and fills zeros into bits 8 - 15.

The type of hardware companding mode needs to be synchronized with the DSP operating system (DSPOS) service library. Therefore, A_LAW must use cg6kliba.r54, and MU_LAW must use cg6klibu.r54.

All DSPs within a resource pool must have the same value.
