Brecis Completes T.38 Interop Testing
Brecis Communications, a systems-on-a-chip and multi-service-access-device
manufacturer, has successfully completed interoperability testing in
Commetrex' T.38 Interop Lab. Testing was performed by Cliff Schornak,
Commetrex' CTO and Mike Wells Development Engineer for the T.38 Lab.
"Brecis' MSP chip implementation of T.38 has passed all 16 interop tests,"
says Mike Wells. "The Brecis testing went well. But that's not always the
case. We can analyze the test results and explain the cause of any
interoperability problem, since the reference standard for the test is
TerminatingT.38. TerminatingT38 is the industry's only technology that
terminates a T.38 transaction, and it's richly instrumented, so we can tell
exactly what's going on. Sometimes, there are no interop problems between
our testing partner's equipment and TerminatingT38, which has become the de
facto industry reference standard for T.38 interoperability. But sometimes
an analysis of the logs indicates a potential problem with another vendor's
equipment that previously came through the Lab. We then advise our testing
partner what changes to consider making."
T.38 is the ITU recommendation for the real-time transport of Group 3 faxes
over IP networks. Gateways with T.38 convey faxes across the IP network
without creating the discontinuities in the data that result from packet
loss when the fax transmission is conveyed using the gateway's voice
facilities. Commetrex maintains that the media-specific processing of T.38
is necessary in access gateways to avoid degrading the fax transmission.

Pulver100 Award: Commetrex Receives Recognition for Second Year
For a second consecutive year, Commetrex has been included in the pulver100.
According to pulver.com, the pulver100 award recognizes private companies in
the communications sector that have substantial real-world deployments and
enjoy significant growth rates. Companies chosen for this award represent
the future of the communications ecosystem. The value chain characterized
by the chosen companies differs substantially from the vertically integrated
telecom model of the last century. The companies prospering in the new
environment have followed the computer and networking industry model with
open interfaces, connectivity de coupled from services, and software
de-coupled from hardware.
"Commetrex is a member of the pulver100 because of the critical role the
Company plays in helping the network-equipment manufacturer develop the
equipment needed to deliver Purple Minutes", noted Jeff Pulver, Found of
pulver.com. (Purple minutes are defined by Pulver as IP-based enhanced
services in the form of cool killer apps created by telecom companies.)
The pulver100 nominations are reviewed each quarter. For the list of
pulver100 companies,visit http://www.pulver.com/pulver100/ to avoid
degrading the fax transmission.
Why Do VCs Waste Money?
No, we're not talking about VCs bidding against each other to fund the
dot-coms without a sensible business plan. This is about the VC that funds
the digital-media telephony-equipment maker. They don't mean to throw money
away; they're just unaware that much of their investment will produce a
negative economic value addition. How? Simple. They are funding the
reinvention of the proverbial wheel. Just a few years ago their companies
had no choice, but now they do. New solutions are available, and not just
for the early stage company. Legacy vendors also have the same opportunity
to save on new product development while they dramatically shorten time to
market and still maintain control of their strategic product platform.
It all has to do with a new value-adding product category defined by
Commetrex. Check out Commetrex' new white paper to learn what its' all
about.

Building an SME Gateway?
"There's gold in them thar hills," is a popular saying originating in North
Georgia, not too far from where Commetrex is located. Well, there's gold in
the small-to medium-sized enterprise (SME) market, which is why the low-end
gateway, or integrated-access device (IAD), market is relatively hot. These
products typically have a DS-1 or DSL connection to the WAN, and derive an
Ethernet data connection and 2-16 analog station ports for connectivity to a
legacy switch or directly to voice and fax terminals. There's also the flip
side where several analog trunks are the WAN interface and IP, voice, fax,
and a few analog interfaces are on the premises side.
One of the critical design issues of such a product is how to acquire the
necessary technologies that implement the line interfaces, speech coders and
echo canceller, fax relay, and packet management. Developing that long list
of technologies in house is not an option. So the decision usually comes
down to whether to acquire the technologies via a fixed-function chip or use
a catalog DSP plus licensed technologies. Often it's a Hobson's Choice: a
fixed-function chip is just that: fixed. And the OEM loses control of his
product. But licensed technologies often require large up-front fees,
per-port royalties, and a healthy dose of software integration. Even then,
the analog trunk management software is generally not available.
But wait!
Commetrex has now enhanced its OpenEndpoint(tm) integrated gateway software
product by adding a highly optimized G.729a/b for the TI TMS320C6000 family
of DSPs. And our recently completed Release 2.0 of our
echo canceller
(ECAN) meets G.168-2000 requirements. G.726 and T.38 are also included in
OpenEndpoint. The 'C6000 is TI's flagship DSP, and it's worth considering
for these products. Pricing for 200MHz chips is approaching $10, giving you
12 non blocking channels of G.729a/b or G.723.1 with ECAN on one low-cost
200-MHz chip. OpenEndpoint even has the software needed to interface with
the analog lines. And did we mention that you can avoid "captive-technology
jail" by licensing the source code?
