Using Cisco Unified Communications Manager to Configure Transcoding and Media Termination Point

  Information About Transcoding and MTP for the Cisco VGD 1T3 Voice Gateway

153

Cisco VGD 1T3 Voice Gateway Software Configuration Guide

DSP Farms

A DSP farm is the collection of DSP resources available for transcoding and MTP services. DSP farms 
are configured on the voice gateway and managed by Cisco Unified Communications Manager through 
Skinny Client Control Protocol (SCCP).

The DSP farm can support a combination of transcoding sessions and MTP sessions simultaneously. The 
DSP farm maintains the DSP resource details locally. Cisco Unified Communications Manager requests 
transcoding services from the gateway, which either grants or denies these requests, depending on 
resource availability. The details of whether DSP resources are used, and which DSP resources are used, 
are transparent to Cisco Unified Communications Manager.

The DSP farm uses the DSP resources in network modules on Cisco routers to provide transcoding and 
hardware MTP services. 

Tip

To determine how many DSP resources your router supports, see the 

“Allocation of DSP Resources” 

section on page 154

.

DSP Farm Profiles

DSP-farm profiles are created to allocate DSP-farm resources. Under the profile you select the service 
type (transcode or MTP), associate an application, 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 SCCP, can use the resources 
allocated under the profile. You can configure multiple profiles for the same service, each of which can 
register with one Cisco Unified Communications Manager group. The profile ID and service type 
uniquely identify a profile, allowing the profile to uniquely map to a Cisco Unified Communications 
Manager group that contains a single pool of Cisco Unified Communications Manager servers.

Transcoding and MTP

Transcoding compresses and decompresses voice streams to match endpoint-device capabilities. 
Transcoding is required when an incoming voice stream is digitized and compressed (by means of a 
codec) to save bandwidth, but the local device does not support that type of compression. Ideally, all IP 
telephony devices would support the same codecs, but this is not the case. Rather, different devices 
support different codecs. 

Transcoding is processed by DSPs on the DSP farm; sessions are initiated and managed by Cisco Unified 
Communications Manager which also refers to transcoders as hardware MTPs. 

This feature provides transcoding at the remote site, without the need for access to the central site 
(see 

Figure 1

).
