A Data/Voice Gateway Provider:
Solving A Customer's Needs
There's been a lot of speculation recently about golden opportunities in Internet
telephony. Predictions range from $2 billion to $8 billion by 2004, and some say a
third of all voice traffic will be carried over the Internet by the turn of the century.
Sounds like a great opportunity for modern day prospectors to make a fortune. But
the question remains, "Is there really gold out there for independent entrepreneurs
now?"
Johnny Brown of Cedar Rapids, IA, says, "Yes." President and CEO of J. M. Best
Communications, Brown is seeing revenues double monthly in a business category
that didn't exist just five years ago. "I see this market exploding," he says, "As my IT
network grows, traffic grows along with it." His phone-to-phone Voice over Internet
Protocol (VoIP) network now serves over 500 U.S. locations as well as international
locations including El Salvador, Taiwan, Costa Rica, Mexico, Panama, Guatemala,
Peru and Honduras. He's planning to add more locations every month through 1999.
HOW HE STARTED
A longtime entrepreneur and problem-solver, Brown started three companies
previously and holds patents and copyrights on his own inventions. After establishing
J. M. Best as a successful ISP, he looked for more opportunities. Internet telephony
seemed a good fit with his existing business. He began researching the possibilities of
becoming an Internet Telephony Service Provider (ITSP) through Internet searches
and visits to trade shows.
His preliminary research led him to a product category that would get him into the
ITSP business: Data/Voice Gateways (DVGs). He wanted a gateway product that
could support phone-to-phone long-distance VoIP, but he was also looking for
additional functionality that would allow him to run and grow his business.
HOW DVGs WORK
A DVG allows conventional phone-to-phone calls to be made over the Internet when
a DVG is at or near the origin and destination of the call.
To begin, the end user dials a local number (which can be on a calling card) and
enters a PIN number. An authentication server then verifies the PIN number and
looks up the phone number on a table to locate the IP address of the remote DVG.
As the conversation begins, Advanced Digital Signal Processors (one per voice
channel) convert and compress speech into data packets and route them over the
backbone or over the Internet or other IP network to the destination. The remote
DVG then uncompresses the data packets back into speech and sends them out by
dialing and connecting over the public telco (PSTN) or private telephone network.
Since the calls at the origin and destination of the communication are local calls,
long-distance charges do not apply, so service providers can profitably offer rates as
low as 7 to 10 cents/minute for calls across the country or around the world.
Depending on the gateway product, up to 24 channels of voice traffic can be
connected to each unit, using T-1 trunks or conventional analog telephone lines via
FXO/FXS ports. An Ethernet LAN port may provide connection to the data network
infrastructure. Some DVG units can be connected to each other, allowing the service
provider to build a large network as the business grows.
PRODUCT PERFORMANCE ISSUES
With the sheer volume of players getting into the VoIP arena, there is a veritable glut
of DVG products available. But, as Brown discovered, some solve inherent problems
better than others do. Here are the issues he felt were most important as he
researched the IT marketplace:
Quality of Service (QoS)
From the early days of Internet telephony, quality of voice transmission has been an
issue. Latency (from routing delays), dropouts (when packets are missing in action)
and jitter (the breaking up of speech when packets arrive out of sequence) are some
problems that have held this technology back. However, new refinements are
becoming available to improve quality to near (and in some cases better than) that of
PSTN calls.
Scalability
Assuming you want your ITSP business to grow, you need a system that will grow
with it. Some do this more easily than others. How many lines can each box support?
Can you add boxes to the stack? Will you have to add special hardware as line
capacity increases?
Authorization & Billing
It takes more than a DVG to run an ITSP business. In order to authorize customers
and handle billings, you'll need a server to support a network of gateways and
manage a centralized database of subscriber information. When calls are completed,
Call Detail Records (CDRs) must be made and passed on to other operators/end
users. A server must maintain mapping and configuration data for the network. A
sophisticated invoicing application is needed for customer billing. Are these
capabilities available in a DVG system package, or must additional hardware and
software be purchased separately? If so, will they all work together as one
dependable system?
Reliability
Is the DVG system redundant and fault tolerant? Is it modular for easy system
changes if required?
Cost
Does the total investment allow you to become profitable in a reasonable time period
and allow you to charge end users a competitive price for the service?
A SUITABLE SOLUTION
Brown chose to build his ITSP business with Franklin Telecom's Tempest system.
For his particular requirements and goals, it was the best choice. Here are some of
the reasons why.
Quality
The Tempest system incorporates new technology that allows the user to make real
time adjustments on the telephone keypad to improve quality of a call on-the-fly. For
example, a user can often improve the sound quality significantly by pressing a
two-key combination. This allows the user to "turn down" latency during a call or to
send more 30ms frames per IP packet, improving call sound quality.
Scalability
The Tempest DVG currently supports T1, FXO, and FXS lines, with each system
handling 8, 12, or 24 lines. It can be scaled by adding more boxes to the stack. All
are connected by a TCP/IP LAN. A T1 speed port on the backbone IP network can
support at least 10 DVG units for a total of 240 voice ports per router (concurrent
calls). The limit to the number of DVG units you can put on a LAN is a function of the
size of the LAN and router.
Authorization & Billing
The Tempest Billing and Authorization Server, which supports credit, debit, prepaid,
and other account types, enables real-time Web-based customer tracking as well as
management of the subscriber database. It authenticates user codes (PIN numbers)
and verifies that the account has sufficient credit. Then, it routes the call by the
timeliest and most cost-efficient means possible.
This server runs on Windows NT with SQL Server and is highly scalable. It can
support a very large network of VoIP Gateways, using state-of-the-art client/server
architecture. Our proprietary software is designed to work with our hardware and is
all part of the complete Tempest DVG system.
Reliability
The system is redundant and fault tolerant, comprised of plug-in modules, which can
be removed/installed on-the-fly.
GOING FOR THE GOLD
Brown has put together a menu of services for his consortium members, typically
other ISPs. The selection of services includes:
Billing
J.M. Best will route, monitor, authenticate, and terminate all voice/fax calls. They will
issue "Minutes of Use" statements with all the information required by ITSPs to bill
and collect from their customers. The company also provides billing settlements
between ITSPs and other carriers.
Marketing
The optional marketing package helps the ISP enter the ITSP business with minimal
work. J.M. Best provides a free service to its members to recruit new customers. It
also provides calling cards, flyers, promotional materials, advertising and PR
materials, as well as on-site marketing support.
Customer Billing
This package provides all billing services and collection and issues payments to ITSPs
twice monthly.
Equipped with the Tempest system, Johnny Brown began building his VoIP business
with his ISP end users. But, he now sees the greatest opportunity in expanding his J.
M. Best network of other Data/Voice gateways domestically and internationally.
