The

Spacevars
0series4
provides a wide range of high density digital signal processor (DSP) modules and a comprehensive set of converged, voice, video, vocoder, fax and data media processing functions. This section describes the possible DSP density values on 
Spacevars
0series
devices (
Spacevars
0model3
,
Spacevars
0model4
,
Spacevars
0model1
,
Spacevars
0model2
, 5400) and the 
Spacevars
0series2
device according to their DSP module configurations.

Channel densities of the

and the
Spacevars

are dynamically determined according to resources (MIPS and memory) required by particular codecs in use. The

5110, 5210, and 5400 platforms use DSP2x modules.

 

Comparison of SBC DSP Modules

Two types of DSP cards are used on 

Spacevars
0series
platforms. The

, and 5400 platforms use DSP2x modules, and the

Spacevars
0product
 
Spacevars
0model3
 and
Spacevars
0model1
 use the SPS100 modules. The number of transcoded sessions supported on the DSP2x and SPS100 modules varies by codec. Available platform bandwidth may also limit sessions depending on packet size. 

The 

Spacevars
0series2
platform uses the high density DSP-LC type of modules.

The table below describes the card differences and associated platforms.

Note

Mixing DSP20 and DSP25 cards (both within a chassis and between active/standby servers in HA scenario) is not supported.
For example, if

Spacevars
0product
-A contains DSP25 in slot 1-3,
Spacevars
0product
-B must also have a DSP25 in slots 1-3. As another example, if
Spacevars
0product
-A has a DSP20 in slot 1,
Spacevars
0product
-B must not have anything other than a DSP20 in slot 1.

Note

Only one DSP20 is allowed in an

Spacevars
0series
chassis, and it must reside in slot 1.
