The

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 Unable to show "metadata-from": No such page "_space_variables"
devices (5100, 5110, 5200, 5210) and the Unable to show "metadata-from": No such page "_space_variables"
device according to their DSP module configurations.Note
Not applicable to the SBC Software Edition.
Channel densities of the SBC 5110, 5210 and 7000 are dynamically determined according to resources (MIPS and memory) required by particular codecs in use.
Comparison of SBC DSP Modules
Two types of DSP cards are used on the
Unable to show "metadata-from": No such page "_space_variables"
platforms. The SBC 5110 and 5210 platforms use DSP2x modules, and the SBC 5100 and 5200 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

platform uses the high density DSP-LC type of modules.The table below describes the card differences and associated platforms.

Mixing DSP20 and DSP25 cards (both within a chassis and between active/standby servers in HA scenario) is not supported.
For example, if
Unable to show "metadata-from": No such page "_space_variables"
-A contains DSP25 in slot 1-3, Unable to show "metadata-from": No such page "_space_variables"
-B must also have a DSP25 in slots 1-3. As another example, if Unable to show "metadata-from": No such page "_space_variables"
-A has a DSP20 in slot 1, Unable to show "metadata-from": No such page "_space_variables"
-B must not have anything other than a DSP20 in slot 1.Only one DSP20 is allowed in an SBC 5x10 chassis, and it must reside in slot 1.
