Adax Announces the APC-DCX - Digital Circuit Exchange; Single Card Incorporates Channel Bank And Multicast Functions.

BERKELEY, Calif.--(BUSINESS WIRE)--May 23, 1995--Adax, Inc., a leading developer of technology for wide area networks (WANs), today announced an innovative server-based digital circuit switch designed to give network planners an affordable, easy to use solution for high-speed broadcast applications.

The new APC-DCX (Digital Circuit Exchange), part of the Advanced Protocol Controller (APC) family, facilitates the simultaneous transmission of high-speed data, video images and voice over T-1 and E-1 circuits without the need for an expensive external multiplexer (or channel bank) to allocate circuit bandwidth. In addition, the protocol independent DCX is the first server-based product to make possible the simultaneous transmission of video to multiple destinations.

According to Dr. Barry Zuckerman, Adax founder and President, "Content providers are going to love the DCX. No other card-based system provides essentially unlimited broadcast switching. DCX is the natural choice for high-speed broadcast applications like video." Because of their low cost and high bandwidth, T-1 and E-1 circuits (1.544 MBps and 2.048 MBps respectively) are ideal for distributing video applications. Ordinarily, a device is required to manage the flow of the various data streams, or "conversations" over these lines. In many cases, this task is performed by a costly external channel bank attached to the network applications server. With the DCX plug-in module, however, Adax offers a far less costly, more capable alternative to a traditional channel bank.

"We wanted to give our customers something more than a low-cost card that could reside in a server and perform the functions of a channel bank," said Henry Matthes, Marketing Manager for Adax. "The Digital Circuit Exchange is a truly imaginative design; we've put a multicasting, digital cross connect switch in a modular package that users can plug directly into their servers," he noted.

The Adax Digital Circuit Exchange provides all of the functionality of a traditional T-1/E-1 drop and insert channel bank, plus unique multi-casting capabilities, on a single, inexpensive network interface card. Multicasting - the ability to send the same set of data to several destinations at once - is used for many network applications. The Digital Circuit Exchange is ideal for content providers and high-bandwidth applications such as distributed digital video and multimedia.

The number of broadcast destinations for each server equipped with DCX is limited only by the number of the server's card slots. A twelve slot server, for example, can take data from an application and simultaneously transmit it to twenty-four remote locations at 2.048 million bits per second each.

The DCX also delivers significant cost of ownership advantages versus external channel banks. Less expensive to purchase and easier to manage and upgrade, the DCX stretches network dollars. The DCX is completely compatible with existing APC implementations.

Available immediately in ISA and MicroChannel versions, DCX suggested pricing begins at $3,475.
