CUBE Transcoding on the SPA DSP Voice Card


CUBE (SBC) transcoding can be done using the SPA DSP services on the SPA DSP card. The SPA DSP card contains digital signal processors and related hardware that provide voice transcoding capability for service providers and enterprise businesses.

Transcoding is the process of translating one type of media stream or codec into another type of media stream or codec. For example, PCMU into G.726-32.

Transcoding is triggered by a response from the callee endpoint, indicating that none of the codecs in the initial request are acceptable. Responses that trigger transcoding are as follows:

415 - Unsupported media type (SIP)

488 - Not acceptable here (SIP)

65 - Bearer Capability not implemented disconnect cause value (H.323)

When transcoding is triggered, the SBE places a transcoder in the media path between the incoming and outgoing DBEs. The SBE then sends a new request to the callee, with a new codec type generated by the transcoder. The SBE may have to iterate through the list of codecs until it finds one that the callee accepts. Once a codec is found that is accepted by the callee, the call is connected and media transmission begins.

This example shows how to configure CUBE Transcoding on the SPA DSP Voice Card. Each segment of the example is explained below.

Transcoding Configuration

In the transcoding segment of the example, the voice-card command specifies the slot number of the SPA DSP voice card and enters the voice card interface configuration mode.

The dspfarm profile command enables the DSP farm service for the specified DSP farm profile, enables transcoding, and enters DSP farm profile configuration mode. After the dspfarm profile command, the valid codecs are listed. The codec list must contain codecs that the SBE is hard-coded to recognize.

Interface Configuration

The interface segment configure the SBC interface, establishes 23.30.1.101 as the primary address, and configures two secondary addresses.

SBC SBE Configuration

Configures the SBC, SBE, and associates the dspfarm profile.

Adjacency Configuration

Configures the Nav_A and Nav_B adjacencies.

Call Policy: Adjacency Connection

Establishes the connection between the Nav_A and Nav_B adjacencies.

CAC Table: Codec Enforcement

(Optional) Enforces which codecs each side of the call is allowed to use.

Transcoding CUBE in VDBE mode on SPA DSP Voice Card

The following example shows how to configure CUBE transcoding in Virtual Data Border Element (VDBE) mode on the SPA DSP Voice Card. The VDBE is a resource partition within the DBE and functions as a media gateway. Each VDBE is controlled by a separate SBE using the H.248 (Megaco) protocol. VDBE is used only in distributed model of CUBE.

Transcoding Configuration

The Transcoding Configuration is the same as the other examples in this module.

SBC DBE Configuration

This segment configures the H.248 (Megaco) protocol, including the H.248 timers and controllers.

The control-address is the IP address of CUBE (SBC).

The remote-address is the IP address of the media gateway (VDBE).

To validate packet delay/jitter/loss using Wireshark, you may need to configure the vad off override command, in the dspfarm profile in the transcoding configuration segment, to prevent comfort noise generation, which is active by default. This is dependent on the type of media stream in use. For example, if the media stream contains many long gaps of silence, comfort noise may be generated and total amount of RTP packets may vary.
