Nuera Achieves Interoperability
Nuera Communications, Inc. has completed T.38 interoperability testing in
Commetrex' no-charge T.38 Interop Lab. Nuera is a leading provider of
Voice-over-Internet Protocol (VoIP) infrastructure solutions that work
over media such as cable, wireless, copper, and fiber. Commetrex, Nuera,
and other testing partners believe the industry will benefit if service
providers can assume that T.38-capable gateways from different vendors
will interoperate.
Bill Ingram, Nuera CEO, said, "The testing was done entirely over the
public Internet. Together with Commetrex, we were able to iron out a few
differences in the interpretation of the T.38 Recommendation before
establishing full interoperability. We are glad to participate in a
program such as this that has the potential to benefit our customers
while it boosts the industry as a whole."

is no cost involved.
H.323 Version 4.0 Requires T.38
According to Recommendation H.323 Version 4, Annex D, T.38 is required
for Release 4 conformance. According to the Recommendation, support for
fax shall be provided by T.38. The relevant paragraph is reproduced below.
D.2 Scope
The scope of this Annex is to use H.323 procedures to transfer T.38
packets in real time over the IP network. H.323 entities supporting
facsimile capabilities shall use T.38 to support real-time facsimile
services as described in this Annex.
This presents vendors with a problem: Although G.711 produces messy,
high-error-rate faxes, it has the benefit of interoperability. On the
other hand, T.38 produces clean faxes, but presents an interoperability
problem. T.38, having been released in 1998, is a relatively new standard.
A service provider that intends to use T.38-capable gateways from multiple
vendors simply cannot assume interoperability. This prompted Commetrex to
found the T.38 Interop Lab to provide the industry with a clearinghouse
for testing and the posting of results. A vendor will be able to visit
this forum to quickly learn whether a product has been tested and what
equipment with which it is interoperable.

Interstar Ships TerminatingT38 on Value-Adding Service Platform
Congratulations to Interstar Technologies, Inc., a recent recipient of
Technology Marketing Corporation's 2002 INTERNET TELEPHONY® Conference
and Expo 'Best of Show' award for its XMediusFAX T.38TM. XMediusFAX T.38
is a fax-over-IP server solution that fax-enables enterprise networks
without the need for expensive computer-telephony interface boards or
leased analog lines.
Interstar's recipe for success included the best ingredients like
Commetrex' award-winning TerminatingT38TM, winner of CT EXPO 2001
'Best of Show' award. TerminatingT38(tm) is a combination of Commetrex'
ITU T.38 and T.30 fax protocol engines, giving the developer of a
network-service platform or an enterprise fax server the technology
necessary to terminate T.38 (IP network) real-time fax transmissions
the same as it would real-time faxes from the PSTN using analog modems.
"Interstar is Commetrex' first customer to ship product using our
TerminatingT38 as a main component," says Cliff Schornak, Commetrex' CTO.
"We're especially pleased that they have also received industry
recognition for product innovation for a product that includes one of
our technologies. We believe forward-thinking technology solutions like
XMediusFax and TerminatingT38 will provide much-needed manna for
developers of next-generation IP solutions."
Commetrex offers TerminatingT38 as licensed software for incorporation
into your proprietary environments. TerminatingT38 makes no assumptions
regarding the connection setup, such as H.323 or SIP, nor does it assume
a particular API for the application software.

From the Voice on The Net (VON) Show Floor
Spring 2002 VON was the place to go to understand the issues affecting
the IP Communications industry today. Last month's show held in Seattle
provided a mix of service providers, enterprise customers, and equipment
vendors.
"SIP was the buzz word at this year's show. Everyone seemed interested
in getting the latest on SIP," recounted Paul Baron, Commetrex' Director,
Worldwide Sales. "The other buzz word was openness. Equipment vendors
were looking for modular, open systems and products that would plug and
play neatly into their strategic platforms. And this was outstanding for
us because we were showcasing a product that fit those criteria perfectly.
Our Open Telecommunications Framework® (OTF) Kernel received a lot of
positive feedback from show attendees."
Open Telecommunications Framework (OTF) Kernel, is the industry's only
telephony middleware software product that conforms to the ECTF S.100
recommendation, and is not tied to the server vendor's hardware. It's a
pure software product designed to support your media-technology and
connectivity resources.

T-Minus 12 Days To The MSP-H8
Commetrex' MSP H-8 Media GatewayTM (MSP-H8) sets the standard for
affordability for digital-media enterprise servers since it uses host
MIPS for media processing. How about $125 per voice-fax port in high
volume? After 15 years on the market the incumbent's fax board still
cost $400-800 per port, high enough to put LAN-based fax servers out of
reach for the small-to-medium-sized business. It shouldn't be that way and
Commetrex is doing something about it. Want to try it, and OTF, our
S.100-conforming developer's environment?
"This product concept was customer-driven. OEMs asked us for a more
robust product at a better price, and we've responded with the MSP-H8.
Our goal is to provide leadership to the industry by redefining the low
end of the media gateway DSP-resource board market,"says Ben Feldgajer,
Director, Embedded Systems Development.

Commetrex Announces Multi-Media IP Endpoint
Commetrex is pleased to announce the availability of a new, multi-media
IP endpoint product, OpenEnd(tm). OpenEnd is a suite of Commetrex'
media technologies required to implement a voice-fax IP access device
which connects legacy voice and fax terminals to IP-based access networks.
The media-processing technologies are packaged in Commetrex' OpenMedia.
An optional software subsystem that handles FXO interfacing is available
to complete the package.
"So-called integrated access devices are viewed by some as low-complexity
devices," says Bruce Adams, Commetrex' Director, Signal Processing
Technology. "But they're wrong," he continues. "OpenEnd includes DTMF,
G.711, and G.726 for voice. Low-bit-rate vocoders are optionally
available. For robust fax transport we include all the fax modems and
T.38, the ITU standard for fax-over-IP. Then there's caller ID generation.
The optional POTS interface software completes the package. Simply add
your IP (or AAL2) interface and you're almost ready for market."
For the developer of an IP endpoint, Commetrex' OpenEnd is the
recommended foundation. For more information, contact
sales@commetrex.com at +1(770)449-7775 ext. 310
