BladeWare<\/em> and the MSP boards are licensed without media-processing resources. PowerVox adds voice play and record capability to BladeWare<\/em>.The PowerVox SDK provides the necessary development environment; runtime licenses then add a specific number of per-call resources. These runtime resources can be for the BladeWare<\/em> SIP service manager, any MSP-series resource hardware, or the terminating version of any voice codec that supports voice-over-packet networks.<\/p>\n

The play-record resource to be used for a given command is determined by the BladeWare<\/em> system on a per-call basis without involvement by the application. The resource, which is determined by the BladeWare<\/em> resource group configured to support the operation, may be terminating IP or PSTN voice using and MSP board. This means the application can be developed without regard to the type of network (PSTN or IP) or resource to be used on a given call.<\/p>\n

BladeWare<\/em> is a telephony middleware software system that supports both third-party and Commetrex-provided media and switching resources. These vendor-specific resources are isolated from the balance of the OTF Kernel system by Resource Service Managers (RSMs). The resource-specific RSM determines the number of concurrent media-technology resources that have been licensed. It then launches the appropriate Resource Controllers, such as the PowerVox Resource Controller, to support voice play-record for IVR and messaging applications.<\/p>\n

      Overview<\/h2>\n

      A BladeWare<\/em> system provides clear separation between the application and service entities and network-interface and the resources that connect and process the digital-media call streams. These resources are abstracted to render them vendor and resource independent. The binding of the resource-abstraction token to an application and call stream is then handled by the system services independently of the application.<\/p>\n

      BladeWare<\/em> uses an application profile and System Call Router (SCR) routing rules to dynamically bind resources to the application on a per-call basis. For example, the application profile may specify a particular voice coder to use, where routing rules allow the SCR of build a resource group for the application that would be based on whether a call arrived via a PSTN or packet connection.<\/p>\n

      Player-Recorder API<\/h2>\n

      The Player-Recorder provides the functions needed to implement messaging and voice-based digital-media information service systems. The API functions operate on Container Manager Time-Varying Media (TVM) objects.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

      ITU G.726 ADPCM<\/h2>\n

      This ITU standard describes the conversion of a 64- Kbit A-law or \u00b5-law PCM channel (sampling rate = 8000Hz and sample size = 8 bits) to and from a 40, 32, 24, or 16-Kbit\/s channel. The conversion is applied to the PCM bit stream using the ADPCM transcoding technique described in G.726.<\/p>\n

      Uniform Pulse Code Modulation (UPCM)<\/h2>\n

      In uniform PCM, each sample of the incoming signal is quantized to one of 2R amplitude levels, where R is the number of binary digits used to represent the sample. For example, in 8-bit uniform PCM each sample is quantized to one of 256 levels.<\/p>\n

      Configuration Information<\/h2>\n

      PowerVox adds terminating voice to an OTF Kernel-based system. All members of the MSP line of DSP-resource boards are supported, as is the all-IP BladeWare<\/em> IP media server.<\/p>\n
