Corvette dealer races to savings on multi-use network.

For small-to medium-sized businesses with a few remote locations, T1/T3 can be attractive, but simply not affordable.

Visone Motors, Saugus, Mass., one of the nation's largest dealers of classic Corvettes, was looking to link communications with its Pompano Beach, Fla., location.

They discovered that an affordable combination of digital leased lines and multiplexing equipment can draw almost as many raves as a cherry '63 split-window Vette.

With $20 million in annual automotive sales, Tony Visone, president and owner, knows how to make a buck and also how to save one.

"I looked at all kinds of 800 line services and communications products trying to make it work. I just couldn't find what I needed, until I found the data/voice network servers," says Visone.

He chose Micom's Marathon DVNS products which multiplex not just data, but voice, fax, and LAN traffic as well. They work over a single 56 or 64 kb/s or analog (9.6-19.2 kb/s) leased line.

Besides being utilized on these more affordable leased lines, the Marathon multiplexing equipment has a small-to medium-sized business price tag: base price price begins at $1,750 for the Marathon 1K and $2,750 for the higher capacity 5K.

In addition to the affordability of his networking investment, Visone says his new integrated data/voice WAN gives him a nearly inconceivable payback.

"All together we've estimated we're saving $20,000 a month overhead," he says, noting this amounts to a one-month payback.

"More than just eliminating long-distance phone charges, which have always been substantial for us, we can reduce the number of times date is handles, which gives us more control over costs."

The network, which Visone plans to extend each time he adds a new dealership, is an attractive mix of leased line, local area network and multiplexing technology.

At the 20,000 square foot Corvette showroom/sales office in Saugus is a Novell LAN and phones and a voice PBX. The Saugus facility is also linked to a bank located just over a mile away that administrates the dealership's leasing and financing portfolios.

Voice and fax traffic between the Saugus showroom and First City Acceptance Corp. Bank use the PSTN. A 56 kb/s DDSII line connects the Novell LAN via Novell File Servers.

The Marathon Data/Voice Network Servers handle the Saugus to Pompano Beach link.

One 5K in each office routes the LAN data and digitized voice (running at 8 kb/s, compressed down from 64 kb/s PCM) over a 56 kb/s digital circuit from Massachusetts to Florida.

The Marathon configuration chosen by Visone provides one channel for synchronous data and six channel for voice traffic. Marathon uses fast packet multiplexing (FPM) to transport each data/LAN and speech packet in a predictable, low-delay manner.

Additionally, the Marathons compress the data by a 4:1 ration, and compress the voice signal to allow better utilization of the 56 kb/s bandwidth.

The Novell LAN in Saugus in connected through a MicroCom MLB/6000 bridge to the synchronous channel, supporting over 100 PC and several printers.

Voice calls transmitted from the PBX in Saugus to an AT&T keystation in Pompano Beach via the Marathon DVNS multiplexing equipment over the same 56 kb/s line used for the LAN data. With 48 kb/s of voice traffic running during the day, Visone transmits most of the LAN bridge traffic, including files transfers and heavy remote printing, in the evening hours.

The integrated network also allows the firm to place the long-distance Saugus-to-Pompano Beach phone calls as if there was no distance between the locations. All calls made over the 56 kb/s private line are free of the pay-the-minute toll charges of the PSTN.
