Delivering on the Promise of ATM; ADC Kentrox to demonstrate voice over T1 ATM at ComNet.

PORTLAND, Ore.--(BUSINESS WIRE)--Jan. 16, 1995--ADC Kentrox announced today that they will demonstrate voice over T1 ATM at the upcoming ComNet trade show.

ATM is being touted as the networking technology of the decade. To be beneficial to the average network administrator, ATM must be able to efficiently handle voice, data and video traffic. To help promote the fact that ATM is available today, the company decided to highlight the flexibility of their T1/E1 ATM Access Concentrator (AAC-1t) and it's VBR (variable bit rate) and CBR (constant bit rate) module capabilities.

In the live point-to-point demonstration, data traffic feeding from a Cisco router and voice/fax traffic compressed via the PCSI +100, is adapted to ATM cells and multiplexed by the AAC-1. The combined traffic is transported on a point-to-point T1 ATM connection with an identical application set on the other end. The same applies to ATM switching networks.

"Although initial ATM applications are focused purely on data, ATM technology is designed for voice and data integration. The AAC-1 supports intended ATM use by allowing the user to accept voice and prioritize its transport, ensuring end-to-end delivery. Using voice compression technology, provided by PCSI for this demonstration, users minimize bandwidth needed for CBR traffic, ensure the integrity of signal in information and resolve echo cancellation issues which are not addressed in ATM switching backbones," noted Randy Brumfield, senior product manger -- ATM/SMDS products for ADC Kentrox.

ADC Kentrox will be in booth #1320 at ComNet. For additional information the company can be contacted at 800/733-5511 or at [e-mail] via e-mail.
