Internet telecom began as a revolution in technology. The concept of sending
voice across a data network, in packet format, has been nurtured by a hope of
eventually creating new markets, but for a long time that hope remained latent.
Today customers are demanding a different kind of communications infrastructure
to line up more closely with the different kind of business environment (shaped by
the Internet) in which they find themselves operating. Likewise, service providers
are beginning to come forth with new ideas about how to deliver features and
applications to their customers.
The local exchange carrier market has become ground-zero for much of the work
being done in Internet telecom today. Particularly at the local level, competitive
and incumbent carriers alike are realizing that just providing dial tone (for
Internet or telephony) won't be enough to succeed long term. Carriers are starting
to have to do the one thing they've always avoided: respond to the needs of
individual business customers. As a result more intelligence will be pushed from
the customer premises into the local loop and network edge.
The technology to make it all happen, of course, is being put in place today.
Just look at the development of the gateways, softswitch, and the broadband
voice-over-DSL.and DOCSIS cable deployments to see how the new generation of
voice/data infrastructure is as much about facilitating service creation and
delivery as it is about creating a more economical transport. Today, service providers are finding alternative and innovative methods for the delivery of voice services on top of DSL lines and coaxial cable lines.
At the same time as the carrier world is being shaken up by convergence, the
enterprise communications market is undergoing changes of equal if not greater
proportions. As e-business practices become a more integral aspect of enterprises
across the board, reliance on communications will only increase. The latest
trends in IP PBXs have already begun to reflect this concept. In general, hardware
will be de-emphasized at the enterprise level, and displaced by distributed,
network-based software platforms, managed remotely.
On the public network side, mobile wireless has become the most visible
intersection of telephony and the Internet, a crossing that will be galvanized by
third-generation technology. Within the enterprise, the convergence promise of
"one-wire" infrastructure is quickly giving way to a "no-wire" model.
Nuntius technology enables the transmission of voice, fax and modem
traffic over an IP or ATM backbone network. The software products accomplish this
in three functional areas. These functions are designed to execute in a
distributed fashion on programmable Digital Signal Processors (DSPs) and RISC and
CISC Microprocessors. The three functional modules are Signal
Processing Software, Telephony Processing Software and
Protocol Processing Software.
