System Release 6.1 CompactPCI for Windows

Release Update 72

Media load 9F-MC supports a total of 11 DSP conference resources or DCB devices,

each represented in the Audio Conferencing (DCB) API as a device dcbBnDy. It is the

last DSP/DCB device with the maximum conference size of 90. Use the

dcb_dsprescount( ) function to obtain the available conference resource count for a

specified DSP.

To differentiate with the previous media load 9F, the string -MC is added to the pcd and

configuration file names.

Note: For the smaller sized conferences, conference size is limited to 16 parties without

bridging. Conference bridging can be used on the smaller sized conferences to effectively

expand a conference beyond the maximum size. Conference bridging consumes

conferencing resources, reducing overall board conference density.

Media Load 10F for DM/V4800BC Media Board

The features and channel densities provided by media load 10F on the DM/V4800BC

Media Board are as follows:

There are 420 total voice resources. Any combination of the voice features (basic voice

and FSK) can be used up to a total of 420. (Transaction record is not supported.) In

addition to these voice resources, 32 conferencing resources (with echo cancellation and

tone clamping) can be used.

Notes:1. The ability to sustain 100% load plays/records on all 420 voice channels is dependent

upon several factors such as the audio length and the simultaneity of the playbacks and

records. Heavy simultaneous plays or records above ~ 300 channels can cause quality

degradation on the audio in these particular cases:

• Long audio lengths; the longer the audio, the more likely degradation can exist.

• Simultaneous voice I/O operation start on all channels; if all channels are instructed to

start the I/O operation at the same time, it will likely cause noticeable degradation.

• Records are more stressful on the resources and are more likely to produce

degradation than playbacks.

Under normal field conditions, calls are usually spread among channels at different start

times, causing a natural staggering of the I/O operations. Also, they are typically of

different lengths and may terminate at different times. This statistical behavior of calls
