Configuring the Cisco DSP SPA for the ASR 1000
Series
This chapter provides information about configuring the DSP SPA for ASR 1000 Series on the Cisco
ASR 1000 Series Aggregation Services Routers, also referred to in this document as the SPA-DSP. This
chapter includes the following sections:

Configuration Fundamentals Configuration Guide, Release 2 and Cisco IOS Configuration
Fundamentals Command Reference publications that correspond to your Cisco IOS XE software release.

Voice Transcoding Overview

This section provides a high-level overview of how the voice transcoding functionality is configured.
After you insert the SPA-DSP in the SIP, the SPA-DSP is activated, and you can identify the status of
the SPA-DSP, by executing the show platform command. If the SPA-DSP is operational and working
fine, the show platform command output will display OK in the Status for SPA-DSP. Before you
configure the voice transcoding functionality, you must enable the SPA-DSP. After you enable the voice
card and set the SPA-DSP in DSP farm mode using the dsp services dspfarm command, you can create
the DSP-farm service profiles.

DSP Farm Profiles

DSP-farm profiles are created to allocate DSP-farm resources. DSP-farm profiles can only be created
after you set the DSP SPA in DSP farm mode. Under the profile, you select the service type (transcode),
associate an application (SBC), and specify service-specific parameters such as codecs and maximum
number of sessions. A DSP-farm profile allows you to group DSP resources based on the service type.
Applications associated with the profile, such as SBC, can use the resources allocated under the profile.
You can configure multiple profiles for the same service. The profile ID and service type uniquely
identify a profile, allowing the profile to uniquely map to a SBC application. After creating the profile,
you need to attach the profile to an application and enable the DSP farm profile.
