Supported Features

The Cisco SPA-DSP for the ASR 1000 Series includes some of the following basic features:
• Enhances the Cisco ASR 1000 Series Aggregation Services Router capabilities by providing DSP based
• Translates one type of media stream (voice) to another type of media stream that uses different media
• Enables translation between different packetization settings (transrating), and provides DTMF
• Provision to configure S/BC as a Unified SBC or Distributed SBC with on-board DSPs or as a centralized
• Faceplates LEDs to indicate SPA status.
• Voltage and temperature monitoring.
• Supports online insertion and removal (OIR).
• Provides a jitter buffer to be able to do packet loss concealment.
• Enables transcoding of voice packets for IPv4 (VoIPv4) as well as IPv6 (VoIPv6).
Inband DTMF Interworking
The Dual-Tone Multifrequency (DTMF) dialing consists of simultaneous voice-band tones generated when
a button is pressed on a telephone. The use of DTMF signaling for this feature enables support for advanced
telephony services. Currently there are a number of application servers and service creation platforms that do
not support media connections. To provide value-added services to the network, these servers and platforms
need to be aware of signaling events from a specific participant in the call. Once the server or platform is
aware of the DTMF events that are being signaled, it can use third-party call control, or other signaling
mechanisms, to provide enhanced services. Examples of the types of services and platforms that are supported
by this feature are various voice web browser services, Centrex switches or business service platforms, calling
card services, and unified message servers. All of these applications require a method for the user to
communicate with the application outside of the media connection. The DTMF Events Through SIP Signaling
feature provides this signaling capability.
