D2 Technologies and Commetrex Announce Partnership
D2 to offer Commetrex’s MultiFax Group 3 Fax Software on the Texas Instruments TMS320C54x Family of DSPs

For Immediate Release

Norcross, GA, March 2, 1999 - D2 Technologies and Commetrex Corporation announced today at Computer Telephony Expo Spring ‘99 in Los Angeles that the two companies have formed a partnership to port Commetrex’s MultiFax™ Group 3 fax modem software to the Texas Instruments TMS320C54x series of DSPs. D2 will license the resulting software to its customers. First shipments of D2’s fax products are expected in April of 1999. Later in the year the companies will also jointly develop a fax over packet solution.

"The TI ‘C54x family of DSPs is very popular in the telephony market and we’re extremely pleased to be working with D2 Technologies to expand the availability of MultiFax to this DSP. D2’s extensive telephony and DSP experience make them an excellent partner for Commetrex. D2’s offering our MultiFax technology on the ‘C54x family will complement Commetrex’s ‘C31, ‘C51 and the soon-to-be-released ‘C6x version that Commetrex will support on its MSP/CX Media Gateway and offer to OEMs." said Martin Lippman, Vice President of Marketing at Commetrex.

"We chose Commetrex’s world-class MultiFax technology because it is market-proven: It is currently running on 7 different platforms and has 6 years of field experience. Our alliance with Commetrex will enable D2 to expand its already comprehensive library of voice and telephony algorithm products and VP Open Framework™ to include Group 3 fax modem support. D2’s new off-the-shelf software components will include: V.21, V.29, V.27ter and V.17 data pumps." said David Wong, President of D2 Technologies. "We will be jointly expanding our fax technology to address the exploding FoIP market."

VP Open Framework
D2’s fax software will be fully compliant with D2’s VP Open Framework architecure, which provides all the necessary system support on the DSP for a variety of voice processing applications. VP Open allows DSP developers to easily integrate the fax software modules with D2's other industry-leading algorithms such as DTMF and Universal Tone Detection, Echo Canceller, and voice coders. D2 also plans to integrate the fax modules into a number of upcoming integrated software products for LAN fax, unified messaging, and voice/fax over IP systems.

MultiFax Commetrex’ MultiFax adds software-defined Group 3 fax capability to DSPs. MultiFax was first introduced as a fax software addition to the Natural MicroSystems (NMS) (Framingham, MA.) VBX boards in 1993 and was ported to their AG boards in 1995. NMS has licensed MultiFax and offers their product under the tradename NaturalFax. MultiFax has also been ported to BICOM’s (Monroe, CT) LS-E family of voice boards under the tradename BICOMFax. Computer Communications Specialists, Inc. (CCS) in Norcross, GA and Commetrex Corporation jointly incorporated MultiFax into CCS's FirstLine™ product. MultiFax is the technology core of Commetrex’ PowerFax M-Series of high-density intelligent fax boards and Commetrex is basing the fax component of its TMS320C60-based MSP/CX Media Gateway on the technology.
