DSP Profiles
DSP-farm profiles are created to admeasure DSP-farm resources. Under the profile, you
select the account blazon (conference, transcode, MTP), accessory an application, and specify
service-specific ambit such as codecs and the best cardinal of sessions. A
DSP-farm contour allows you to accumulation DSP assets based on the account type.
Applications associated with the profile, such as SCCP, can use the assets allocated
under the profile. You can configure assorted profiles for the aforementioned service, anniversary of which
can annals with one Cisco Unified Communications Manager group. The contour ID and
service blazon abnormally analyze a profile, acceptance the contour to abnormally map to a Cisco
Unified Communications Manager accumulation that contains a distinct basin of Cisco Unified
Communications Manager servers.
When the DSPs are ready, the DSP contour is configured appliance the dspfarm contour command.
In this example, because transcoding is appropriate on Router1, the dspfarm contour 1
transcoding command is used. On Router2, the dspfarm contour 1 conferencing command
creates a contour for conferencing.
Because both G.711 and G.729 are acclimated in this deployment, assorted codecs are enabled
in both the transcoding and conferencing profiles appliance the codec codec-type command.
Configurations for Router1 and Router2 are provided in Examples 2-6 and 2-7.
Example 2-6 Creating a DSP Contour on Router1
Chapter 2: Considering VoIP Design Elements 109
Router1(config)#dspfarm contour 1 transcode
Router1(config-dspfarm-profile)#codec g711ulaw
Router1(config-dspfarm-profile)#codec g711alaw
Router1(config-dspfarm-profile)#codec g729ar8
Router1(config-dspfarm-profile)#codec g729abr8
Router1(config-dspfarm-profile)#codec g729r8
Router1(config-dspfarm-profile)#maximum sessions 6
Router1(config-dspfarm-profile)#associate appliance SCCP
Router1(config-dspfarm-profile)#no shutdown
Example 2-7 Creating a DSP Contour on Router2
Router2(config)#dspfarm contour 1 conference
Router2(config-dspfarm-profile)#codec g711ulaw
Router2(config-dspfarm-profile)#codec g711alaw
Router2(config-dspfarm-profile)#codec g729ar8
Router2(config-dspfarm-profile)#codec g729abr8
Router2(config-dspfarm-profile)#codec g729br8
Router2(config-dspfarm-profile)#maximum sessions 2
Router2(config-dspfarm-profile)#associate appliance SCCP
Router2(config-dspfarm-profile)#no shutdown
Note Because mixed-mode conferencing is configured, the two configured conferences
require a abounding DSP. If alone G.711 would be allowed, a distinct DSP on a PVDM2 would allow
up to eight conferences.
