Just one of Dialogic's Partners....Parity Systems
I found this on the Parity home page. I would like like to think that this is one story of many among a whole slew Dialogic OEM partners. There seems to be an interesting note (no pun intended) with this news message. Please note...Though there is no date on it, the bulk of users using the Pentium
Million-Dollar Savings
Two million call minutes per month
Three weeks to build
One VOS system.
PCS Telecom has built a PC-based telephone switching platform that sets a new record: 240 lines in one PC. That's ten
T-1 trunks for the system they designed for a long-distance reseller and debit-card service provider. "We're replacing his
million dollar switch, basically," says David Dragon, PCS's VP of development.
PCS is shifting the bulk of its customer's established traffic to a Dialogic SC bus-based system that uses a Pentium
processor on a 20-slot backplane, RAID (redundant array) hard drives, and fiber connections. Our former installations
were PEB-based on multiple nodes," Dragon observes. "Now with SCSA we can do much higher density in one PC
chassis, which is a lot more cost-effective, and more scaleable."
One PC
"The good thing about a single chassis is it allows us to compete with larger switch manufacturers. We can offer the
custom features and control that larger manufacturers cannot provide, while also offering the same density at fraction of
the cost. We can be very competitive," says Dragon. Future plans include plugging T-1s into all 20 slots and then
spanning multiple chassis with SCxBus adapters.
Three Weeks
The application took three weeks to program from start to finish using Parity Software's VOS 5 applications language,
and Dialogic's SCSA based system release 4.1SC. Voice resources and network interfaces are provided by four
D/240SC-T1s and six DTI/240SCs; interconnection and timeslot switching is accomplished over the SCBus.
Two Million Minutes
PCS's customer resells "a couple million minutes a month" of long distance, dialing callers back and providing U.S. dial
tone. Given this dial tone, international callers can dial out across the globe and pay lower U.S.-carrier rates. The voice
script for this application, prompting callers to input their account or debit card number, can be played over 96 ports at a
time; PCS is working on exceeding that too.
With so many switchable T-1 lines, Dragon's firm can hook up multiple carriers to the switch, each with rates that favor
particular destinations. And because all are accessible over the same bus and so many timeslots are available he can
implement a sophisticated least-cost routing function for his end user. As international calls are placed, they are matched
by their country code against a rate table. "By using our trunk groups along with our rate tables, we can route those calls
through the T-1s that we specify," says Dragon. This way calls to Brazil may go out through MCI and calls to Holland
through Sprint. In addition, if a large volume of calls are made to destinations that are in the switch's local area, say, from
South America to the New York City area PCS's least-cost routing algorithms allow the switch to call out on a local
exchange carrier trunk, saving the reseller even more in long-distance charges.
Dragon is effusive in his praise for Parity Software's and Dialogic's tech support staffs. "With our systems running phone
companies, we need a very reliable product," added Dragon. "Using Dialogic and VOS allows us to sleep at night." |
