SangomaBladeWare HMP, Commetrex’ host media processing telephony middleware, has established the industry benchmark for robustness, scalability, and extensibility. And BladeWare’s TerminatingT38 and G.711 pass-through fax support have set the standard for interoperability and function. Now, Commetrex has added support for PSTN connectivity to BladeWare with its recent announcement of support for the complete line of Sangoma analog and digital telephony boards. By interfacing the Sangoma PCI and PCI Express PCM telephony interfaces via BladeWare’s MSP (Media Stream Processor) Resource Service Manager (RSM) BladeWare’s call-control, fax send-receive, and voice play-record facilities are available to the BladeWare OEM for PSTN applications. A BladeWare application can now support analog and digital PSTN telephony on the same system at the same time as the SIP RSM provides IP connectivity.

BladeWare normalizes all call control and resource APIs for the client application, so applications need only be developed once for SIP or MSP. In fact the same application can make and accept calls without regard to the network interface being used, relying instead on BladeWare’s call-routing feature to determine the network-interface resource-SIP, analog, or digital-to be used for a particular call.

It is important to note that BladeWare’s media processing is performed on the PC using host MIPS. So, just as the SIP RSM uses the PC’s network interface, the MSP RSM uses the Sangoma boards. And once the media stream is on the host, the same signal-processing software processes it, regardless of the interface used. So the MSP boards aren’t fax boards or voice boards; they are PCM-interface boards. But with BladeWare’s media-processing resources, they provide all of these functions licensed on a maximum-concurrent-port basis. You license only the media you need and only the number of ports you need. Why pay more?

The MSP product line includes:

Commetrex also makes available its exclusive OpenMedia streams-processing environment, the same media framework used by BladeWare, but available separately for the OEM developing to a proprietary telephony environment. The combination of OpenMedia and the affordable MSP boards give the engineer the ultimate in signal-processing development productivity.

The following runtime licenses are available to configure an MSP-based system to your specific requirements:

  • MSP E/T: single-, dual-, quad-, and octal-span digital boards with robbed-bit and ISDN signaling
  • MSP FX S/O: 2-24-port intermixed analog station and office interfaces
  • MSP BRI: 2-24 ISDN basic-rate interfaces

Since these runtime licenses are independent of the MSP resource, you only need purchase what you need. For example, suppose your system has 8 ports of analog and 30 ports of ISDN digital for a total of 38 channels. If you want all your channels to support voice but never need more than, say, two ports of fax, you purchase 38 ports of voice and two ports of fax. The faxes can be on any of the 38 channels.oreover, the media licenses can be purchased independently of the boards. This means you can inventory the boards, then purchase the necessary runtime licenses when your customer places and order. If a customer needs two spans of T1 today, but is growing, shipping a quad-span board, but with runtime licenses for two spans, is an affordable way to scale a system without a service call. Think of it as the ultimate of just-in-time inventory.
