DSP.C5x[x].NumTxTimeSlots

Specifies the number of timeslots on which the DSP can transmit data.

Syntax

DSP.C5x[x].NumTxTimeSlots = numberslots

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

Access

Read/Write

Type

Integer

Default

Allowed values

0, 16, 32, 128

Example

DSP.C5x[2..5].NumRxTimeSlots = 32

Details

Specifying 0 timeslots turns off the channels for the specified DSPs.

Caution:

In order to change the DSP.C5x[x].NumTxTimeSlots settings, you must be familiar with how CG board DSPs connect to on-board data streams. Each logical DSP number belongs to a group that shares a specific TDM data stream. If you request too many timeslots for a group of DSPs on a stream, the board does not boot and returns a resource error. For information about CG 6000C board switching, refer to CG 6000C switch model.

Each stream has a maximum of 128 transmitting and 128 receiving available timeslots. The total number of timeslots specified for the DSPs on a stream cannot exceed 128 transmitting and 128 receiving timeslots. The following examples illustrate this rule:

Stream configuration	Timeslots	Status
8 DSPs and 16 timeslots per DSP	128	OK
4 DSPs and 32 timeslots per DSP	128	OK
8 DSPs and 32 timeslots per DSP	256	ERROR

For example, conferencing applications can require more than 16 timeslots per DSP. Increasing the number of timeslots per DSP allows more participants per conference call. For more information about using this keyword in conjunction with conferencing applications and determining which streams are attached to logical DSP numbers, refer to the NaturalConference Developer's Reference Manual.
