Carrier Class Internet Telephony Gateways

Much has been said about what it takes to deserve the moniker "Carrier Class." I think everyone will agree that, in the end, it all boils down to 2 things: Scalability and Reliability. The products featured on the following pages offer both of those attributes. You want scale? Try Lucent’s 28 T1-span PacketStar Internet Telephony Server. Or what about Transmedia’s 100,000-port capacity? Well, not every one of these products has that kind of scale, but we figured we’d list those that offered at least a single T1/E1 capacity. We’ve also included the latest development platforms from Dialogic and Natural MicroSystems for those of you interested in building your own gateways.

The interesting thing is that when considering these vendors for this roundup, it struck us that over the course of about a year and a half, since the premier of Internet Telephony, we’ve gone from talking about 4-port black box PC-to-PC gateways to mammoth Carrier Grade solutions. Amazing. Well, now that we’ve seen the advent of these packet-switching behemoths, it’s time for vendors to ramp up the development of applications and services to run on them. (They’re already doing that, just check out the Services section) One final note: This industry moves at lightning speed. We’re all witnesses to that fact. So use this list as a starting point when checking out what the vendors have to offer, and keep your eye glued to TMCnet.com’s scrolling news marquee at www.tmcnet.com. You never know when the next Carrier Class gateway will roll off the assembly lines.

The Castle Networks C2100 Services Mediation Platform (SMP) is a next generation central office (CO) platform built from the ground up to switch both voice and data traffic. The C2100 SMP unbundles voice switching from Class 5 equipment and allows service providers to quickly expand into regional markets offering integrated voice and data services, while providing a platform for peering with long-distance providers and efficiently feeding data traffic to ISPs.

By applying the economies and efficiencies of data networking technology to the PSTN, the C2100 SMP employs a distributed processing model that unbundles core voice switching from the Class 5 mainframe, while still leveraging its feature-rich software. And, with support for data inherent in its architecture, the platform takes advantage of the ubiquity and reliability of the PSTN to migrate carriers and end users from today’s circuit-switched environment to tomorrow’s converged networks of circuit, packet, and cell technologies. Base system pricing starts at $101,500 and includes a chassis, SCE, CPE, and channelized DS-3 trunk/access module (DXM). For more information, visit www.castlenetworks.com.
