SoftRISC and Commetrex Announce Technology and Marketing Partnership
SoftRISC Communication Systems and Commetrex announced that the two companies
have formed a technology and marketing partnership that will bring Commetrex'
industry-leading fax technologies to applications that use RISC processors for
signal-processing tasks in voice-fax IP endpoints. The combination of
Commetrex' field-hardened technologies and SoftRISC's expertise in
implementing communication applications on RISC processors has produced a
complete fax modem and T.38 fax relay solution on the ARM9E and Intel's XScale
platforms. The technologies are targeted at developers of IP phones and low-
density gateways.
Ashok Setty, SoftRISC's CEO, explains: "SoftRISC's team has been developing
innovative techniques for implementing signal-processing applications on RISC
platforms. We have optimized Commetrex' T.38 fax relay and the fax modem
suite, consisting of V.21, V.27ter, V.29, and V.17, onto the ARM9E and Intel's
XScale RISC processors. SoftRISC's comprehensive voice-fax gateway technology
offers the OEM significant cost savings by eliminating the need to include
DSPs in low-density applications, such as residential gateways and IP
phones."To learn more about PowerRelay and our fax modem suite, visit

Motorola Selects PowerRelay™ for T.38 for StarCore
The RF & DSP Division of Motorola's Semiconductor Products Sector (SPS)
(Austin, TX) is developing packet telephony systems solutions based on the
Networking & Computing Systems Group's (NCSG) family of SMART Network
solutions including Motorola's industry leading StarCore DSP.
Earlier this month, Motorola selected Commetrex' PowerRelay for T.38 and fax-
over-IP technology to enhance the StarCore solution.
According to Jon Devlin, Systems Development Manager of the Packet Telephony
Operation: "We selected Commetrex' T.38 technology because we felt that the
product's interoperability, based on Commetrex' T.38 Interoperability Lab,
would give us a competitive advantage."
PowerRelay for T.38 is Commetrex' real-time fax relay technology that gives
the next-generation network system developer the technology needed to support
standards-based fax in a packet-based network. As a developer of a packet-
telephony system, you can offer a T.38-compliant system for fax over IP, an
I.366.2 system for fax over ATM, or a proprietary implementation should it be
required.

Worldwide Sales at pbaron@commetrex.com or 770.449.7775x420. Visit:

SnowShore and Commetrex Extend MSCML to Support Fax
SnowShore Networks developed Media Server Command Markup Language (MSCML) to
enable IP application developers, infrastructure vendors, and service
providers to bring to market new IP-enhanced conferencing and innovative
services. Eric Burger, SnowShore CTO, explained: "Unlike other proprietary
protocols, which resemble closely guarded treasure maps and are only available
to certain vendors, and then on a royalty basis, MSCML provides a public
roadmap for successful development and deployment of enhanced IP services. We
hope to spur growth of new IP services that will benefit the entire VoIP
market."
"We were pleased to find a command language that allows application and media
servers to interoperate," says Cliff Schornak, Commetrex' CTO. "But
BladeWare's support for TerminatingT38 meant we needed to work with SnowShore
to extend MSCML to support fax in media servers. Now, with MSCML, we can ship
BladeWare to media-server developers with a ready-for-market command language
that supports voice and fax, and is destined for wide deployment."
BladeWare is Commetrex' host-signal-processing middleware for blade servers.

FaxTap Converts Recording of Fax Transaction to Image File
Commetrex is now shipping FaxTap™. FaxTap is an off-line (non-real-time) software
process that converts a recorded PCM file to a TIFF-F file. Call-center quality
systems, brokerages, government agencies, and other entities have a need to
monitor fax transactions between two parties. In some cases, the monitoring is
done by recording the real-time PCM stream for later conversion to a viewable
format on a post-real-time as-needed basis.
In this case, "A fax image that might take one minute to receive will be converted
in 1-4 seconds. So non-real time certainly doesn't mean slow," according to Cliff
Schornak, Commetrex' CTO.
"The function of the system is to convert a linear pulse-code modulation (PCM)
recording of a facsimile session into the original transmitted image. A report is
provided indicating the extent of the success of the conversion in addition to the
document properties that can be extracted from the input signal," Schornak,
explained.
FaxTap, a Win32 dynamic link library (DLL), takes full advantage of Commetrex'
extensive portfolio of field-proven fax technologies, including the fax
modems, PortableT30T, and the Image Conversion Library.

Host Signal Processing Port Densities, You May Find the Results Interesting
You may have read about BladeWare™, Commetrex' host-signal-processing digital-
media platform in previous issues of The Outlook (and in item 3, above). We
did some testing to determine the resource requirements of our C-reference
media-processing technologies. We wanted to know how many channels of non-
optimized code could run on various processors to see how much optimization
work we had in front of us. You may find the results interesting.
Our C-reference code is the baseline we maintain for all media technologies.
If you license our fax modems for the TI 'C6400, for example, you receive the
TI-specific code plus the C-baseline. If we ever have an "issue", we make the
correction to the C-baseline, and then make sure the DSP-specific code
produces bit-exact results.
Using a high-resolution clock, we measured the number of clocks each processor
required to process one frame of call-stream data. The C code for all
reported algorithms was developed by Commetrex, except for G.723.1, which is
out-of-the-box ITU code.
In the table below, the maximum number of simultaneous channels is the number
below the algorithm-column headings. It assumes the processor is doing
nothing else, so a practical implementation would require backing off enough
to allow for other tasks to run. You will see a surprising difference in the
performance of the AMD and Intel processors. We have no idea why, but we're
looking into it.
It's obvious we need to invest in optimizing low-bit-rate vocoders. We'll let
you know how it goes.
