Systems and methods are disclosed for extending digital signal processor (DSP) capability of existing media gateway devices. A system includes a media gateway device, which has a first plurality of voice server cards. Each voice server card comprises a first controller, a first communications interface, and at least one first DSP configured to implement at least one first coder/decoder (codec). The system further includes a communications switch and at least one external DSP server. The external DSP server comprises a second plurality of voice server cards, which each comprise a second controller, a second communications interface, and at least one second DSP configured to implement at least one second codec. The at least one external DSP server is in communication with the media gateway device via the communications switch.

Systems and methods for extending DSP capability of existing computing devices

The subject matter described herein includes methods, systems, and computer readable media for intelligent optimization of digital signal processor (DSP) resource utilization in a media gateway. In one method, it is determined in a media gateway whether predetermined conditions exist for DSP-less IP-IP switching for a call. In response to determining that the predetermined conditions exist, DSP-less IP-IP switching is implemented for the call in the media gateway. After implementing the DSP-less IP-IP switching for the call, it is determined whether a predetermined event occurs that requires insertion of DSP resources during the call. In response to determining that the predetermined event occurs, the DSP resources are inserted into the call during the call.

The subject matter described herein includes methods, systems, and computer program products for transporting ATM cells in a device having an Ethernet switching fabric. According to one method, at least one ingress ATM cell is received at an ATM network interface of a device having an Ethernet switching fabric. Next, the connection associated with which the ingress ATM cell is identified. The ATM cell is encapsulated in Ethernet frame addressed to a media processing resource associated with the connection. The Ethernet frame is forwarded to the media processing resource across an Ethernet switching fabric.

Methods, systems, and computer program products for providing transcoder-free operation in a media gateway are disclosed. In one method, first and second lists of media encoding rates and corresponding indices used by first and second media endpoints of a media stream connection are received. It is determined whether transcoder-free operation is possible for the media stream connection based on the first and second lists. In response to determining that transcoder-free operation is possible for the media stream connection, a transcoder-free connection is established in the media gateway between the first and second endpoints using a single digital signal processor to monitor and map between indices and encoding rates used by the first and second endpoints during the media stream connection.
