Internet Telephony Service Providers Get Smart
September 16, 1998 Inter@ctive Week via NewsEdge Corporation : Even as providers of Internet Protocol telephone services continue to grapple with delivering toll-quality voice calls, some are looking beyond the cut-rate call market to offer advanced telecommunications services to corporate customers. Many of those services are linked to the growing use of collaborative computing technology in business applications.
One of the most aggressive of the so-called Internet telephony service providers (ITSPs) is I-Link Worldwide LLC (www.i-link.net), which since its inception in early 1997 has been pursuing a strategy based on feature-rich packet telecommunications.
I-Link's early lead is due in part to its use of proprietary technology along with the evolving H.323 Internet Protocol (IP) telephony standard, says Bob Bryson, vice president of product marketing at I-Link. The proprietary technology comes from two wholly owned I-Link subsidiaries -- MiBridge Inc. and ViaNet Technologies Ltd.
"The industry is evolving in the direction we're going, but we can't wait for vendors to mature products under the standards process," Bryson says.
Like other ITSPs hoping to broaden their appeal beyond the cost savings associated with long-distance voice-over-IP, I-Link's starting point for feature enhancement is to incorporate elements of the switched public network's Intelligent Network (IN) architecture.
"We're getting the SS7 [Signaling System 7] core code from other vendors, but we're implementing IN using our own technology inside our gateways," Bryson says.
I-Link serves about 35,000 customers in 25 markets and expects to reach 250,000 customers by the end of 1999 as it adds features and functions to its service portfolio, Bryson says. "We think price is a starting point for us in building a market base, but it's just the starting point," he says.
Now And Later
I-Link's current feature set includes integrated voice and fax service, " find- me" calling, conferencing, enhanced e-mail and a variety of custom calling options. I-Link delivers these features using IP-based functions built into its backbone, offering customers lower-cost alternatives than are typically available from incumbent service providers via their IN-equipped circuit switches.
I-Link's next big step is to extend network functionality to the customer premises via what the ITSP calls C4 -- a customer communications control center device being developed by ViaNet. I-Link expects to deploy C4 in the second half of next year, in conjunction with its use of Integrated Services Digital Network (ISDN) and Asymmetric Digital Subscriber Line (ADSL) access lines.
Late last month, I-Link announced that ViaNet had developed a working prototype of C4 that will provide home and small-business customers with up to 24 phone lines over existing connections, depending on access rates. The C4 will function as a private node on I-Link's voice and data communications network, which means that customers with a C4 will own an intelligent segment of the enhanced network, Bryson says. Those customers will pay for a single connection on a fixed-rate basis, with other service charges incurred on an as-used basis.
I-Link will put the C4 at the customer premises, breaking away from the remote H.323 gateway model, in which calls go out from users over analog circuits and are translated to IP at a regional server. Many other ITSPs are looking at similar approaches to expanding their service venues using technology soon to enter the market from other vendors.
Already There
The idea of bringing the gateway to the customer premises is an extension of what's now going on at large businesses, where the growing use of collaborative computing within corporate local and wide area network environments is extending out to public network connectivity over virtual private networks (VPNs). This trend is driving companies to look at adding a voice and videoconferencing component to the data stream via implementation of H.323 technology.
Lockheed Martin Corp.'s Tactical Aircraft Systems group has installed an H.323- based system supplied by Lucent Technologies Inc. (www. lucent.com) to support collaborative efforts to design the Joint Strike Fighter jet jointly commissioned by the U.S. Air Force, Navy and Marines and the British Royal Navy. With a need to coordinate development among multiple vendors and customers here and in the U.K., mixed-media conferencing is essential to keep the project on track and on schedule, says Richard Cox, virtual enterprise coordinator at Lockheed Martin (www.lmco.com).
"These companies share services and help each other with design problems, so there's a need for us to be a virtual company," Cox says. "The old way -- using room-based video teleconferencing -- is an expensive, often time-constrained way to collaborate, and it doesn't lend itself to impromptu meetings."
Concentric Network Corp. (www.concentric.net) was the first ITSP to bring such capabilities into the public networking domain. Last year, Concentric launched a service that uses devices linking the H.323 domain with packet conferencing systems based on the older H.320 standard. This service gives companies accustomed to running conferencing systems over ISDN lines separate from their local area network (LAN) an opportunity to expand their videoconferencing capabilities into the IP domain, mixing video with white-boarding and application sharing over data networks, says Katie Greene, a Concentric spokeswoman.
"We're one of the few service providers right now that enable ISDN-based systems to talk to the IP system," she says. Concentric uses corporate T1 data links to its ATM [Asyn-chronous Transfer Mode] backbone to support high-end videoconferencing. "This is really important to companies that have invested a lot of money in H.320 technology but that don't want to incur the costs and inconvenience of using ISDN lines as they expand their application base," Greene adds.
One of Concentric's first videoconferencing customers is Bay Networks Inc. (www.baynetworks.com), where about 500 staffers use the videoconferencing service each day. Bay has found the Concentric service to be "much more affordable" than its earlier H.320-based ISDN system, E H says Pierre Pellissier, network manager at Bay. "The quality of IP video through the Concentric network is better than any of our other existing ISDN-based video systems," he adds.
Gateway Drivers
Demand for large-scale videoconferencing products from large corporations and ITSPs is driving equipment makers to expand the capacity of their customer premises H.323-to-H.320 gateway products. Lucent will bring out a more scalable version of its Multimedia Communications Exchange (MMCX) server early next year, says Bryan Katz, general manager of IP business development at Lucent. The box is now being tested by several service providers, he says.
Lucent is working to make the MMCX, an Internet call center with 500 ports, easier to use with H.320 systems by simplifying session management tasks, such as allocating encoding algorithms for specific users across the two conferencing domains, Katz says. Simplified session management is a key goal of standards development, as IP telecommunications moves toward endorsement of version 3 of H.323 early next year.
Along with solutions for high-end customers, vendors are moving to make H.323 conferencing and other features affordable for small companies. "Even small companies have sales forces out on the road and branch offices in different locations," says Donald Brown, president and chief executive officer of Interactive Intelligence Inc. (www.inter-intelli.com), a supplier of H.323 software. "There's a real need for collaboration and conferencing, if they could afford it."
Interactive Intelligence sells the Enterprise Interaction Server, a Windows NT- based communications system that unifies the processing of telephony, fax, e- mail and Internet interactions within the corporate networking environment. A new H.323 gateway component links the internal and external circuit networks with the corporate LAN. The H.323 gateway lets companies set up and manage conferences at very low costs, Brown says.
Although Interactive Intelligence initially set out to serve enterprises from a premises networking perspective, the addition of the H.323 gateway has opened an opportunity for ITSPs to use the technology to deliver public network services, Brown says. "We didn't start out planning to supply service providers, but CLECs [competitive local exchange carriers] began coming to us for low-cost solutions supporting integrated messaging services," he says. "Now they're interested in the conferencing component of our technology, as well."
Into The Public Space
Other H.323 vendors report a migration of their products into public networking applications. White Pine Software Inc. (www.wpine.com), which supplies H.323 systems compatible with a range of server platforms, now has beta trials under way with a number of ITSPs and Internet service providers (ISPs), including America Online Inc. (www. aol.com), Concentric, the data operation arm of Time Warner Cable (www.timewarnercable.com) and WorldCom Inc.'s UUnet Technologies Inc. (www.uunet.com), according to Forrest Milkowski, co-founder of White Pine.
"As private companies explore the use of collaborative computing with conferencing, ISPs are saying: 'You're already buying service from us, so let us supply you with conferencing services along with your VPN,' " Milkowski says.
White Pine has developed several products that make conferencing and other IP telephony feature applications manageable over multiple access environments, Milkowski says. Its MeetingPoint software, which works with any H.323-compliant client, supports audio switching, in which a document referred to by a speaker -- and also the person's image if video is involved -- is displayed automatically on the screens of conference participants. MeetingPoint can manage bandwidth allocations to fit the access speeds of individual users, Milkowski adds.
These are precisely the features that Networks On-Line Inc. (www. nol.net), an ITSP subsidiary of Comtech Consolidation Group Inc., needs to take its service capabilities beyond the realm of low-cost long-distance service, says NOL Executive Vice President Donald Brown (not to be confused with Donald Brown at Interactive Intelligence). "Our plan of attack has always been to offer voice, videoconferencing, faxing and other features as part of the package, " NOL's Brown says. "Now we can do that."
NOL, which operates five points of presence in an area that covers a diameter of roughly 400 miles in Houston, uses the White Pine software to offer H.323 services running over ISDN to residential and business customers. At 128 kilobits per second, ISDN can deliver H.323 video feeds at resolution and frame rates that overcome the drawbacks of conferencing over analog dial-up lines, NOL's Brown says.
Along with providing users a turnkey conferencing service that includes installation of gateway equipment at the customer premises, NOL offers a " virtual conference room" service at a rental rate of $5 per hour, which allows anyone to set up a meeting with multiple users.
The White Pine software supports simultaneous on-screen appearance of as many as 10 videoconference participants, although at 128 Kbps, that number of video streams results in poor-quality displays.
The service, launched in July, already has shown market strength, Brown says. "We're seeing more than tire kickers," he says. "We're seeing people willing to pay for services."
NOL is a partner in the global IP telephony consortium run by Gric Communications Inc. (www.gric. com). Brown expects many of the ITSPs in that consortium to move to the same types of services. In fact, Gric appears to be on the verge of implementing a consortiumwide videoconferencing system, probably using a different system from the one used by NOL, Brown says.
The ability to offer such advanced services, coupled with the opening of bandwidth over ISDN, ADSL and cable pipes, could make a big difference in the marketing of IP telephony services to the business market, says Dennis Murphy, vice president of enterprise technology at The Goldman Sachs Group LP (www.gs. com). In the past, Goldman Sachs has gone so far as to buy proprietary videoconference systems for clients so that its brokers can "be in front of them as often as possible," Murphy says. The low cost of offering such connections over H.323 systems will greatly expand the marketing advantage, he adds.
"The highlight of H.323 has been the addition of H.263, the video algorithm," Murphy says, adding there's "a real killer of a difference" between the performance of H.263 and older video-over-circuit-switched systems.
Eventually, high-speed access links will make the video component even more compelling for companies such as Goldman Sachs, Murphy says. "What you need to have is virtual meeting rooms, whether you're in the airport with your laptop, at the office or in the conference room, without having to wonder whether everything will work," he says.
