Nortel Networks to Include Tandberg Data Tape Drive in Its CallPilot Unified Messaging System; OEM Purchase of 8 GB SLR5 Continues String of Contracts Going Back Five Years.

SIMI VALLEY, Calif.--(BUSINESS WIRE)--Jan. 20, 1999--Tandberg Data Inc. Wednesday announced that Nortel Networks (NYSE:NT)(TSE:NTL) is using Tandberg Data's 8 GB-capacity SLR5 tape drive for the Nortel Networks CallPilot unified messaging system.

Tandberg Data is the world's leading supplier of high-speed, high-capacity tape drives and libraries, with OEM customers that include Acer America, Compaq, Fujitsu, IBM, Siemens Nixdorf, Sun Microsystems and many others.

Nortel's CallPilot system is designed to enable users throughout an enterprise to access and manage voice, FAX and e-mail messages. The system integrates voice and fax mail into a common multimedia system, making faxing as private, secure and easy to use as voice mail. In addition, the CallPilot system cost-effectively provides customers with the benefits of unified messaging by integrating with a wide variety of popular e-mail systems.

As standard equipment in every CallPilot system, Tandberg Data's SLR5 provides the means for storage and retrieval of all types of messages as well as backup and restoration for the system's programming.

"The SLR5 offers a variety of features that make it an attractive storage solution for Nortel Networks, but the primary one would be its very high reliability, with a failure rate of less than one percent," said Al Duras, vice president, Distribution Sales and Marketing, for Tandberg Data.

"Our line of tape drives also embodies a technology roadmap that will result in new products with even greater data transfer speeds and storage capacities. We are confident that we will have the right products for today's and future needs of Nortel Networks as well as our other OEM customers," Duras added.

SLR5 Moves Data at 800 KBps

SLR5 is an 8 GB (using data compression) tape drive with a data transfer rate of 760 kilobytes per second. Tandberg Data's SLR line competes directly with like-capacity 4mm DAT drives, offering higher performance in terms of speed and reliability, at a lower cost. Introduced in May 1997 as Tandberg Data's new line of lower-capacity, 5.25-inch tape drives, SLR products are scaleable with a technology base of more than 6 million previously-shipped units.
