Richmond, CA --- April 13, 1998 --- Keyspan, the leading provider of serial
communications cards for PCI-based Macintosh computers, announced the
availability of its SMART SERIAL 6 - T1 Edition. The T1 Edition combines a
SMART SERIAL 6 high speed serial communications card with specially
developed HDLC line drivers and a synchronous PPP Communications Toolbox
tool. This package enables PowerPC Macintosh computers to transfer data
synchronously at T1 rates. Suggested retail pricing is $699.

SMART SERIAL 6 - T1 Edition features
The Smart Serial 6 is an intelligent multiport serial communications card
for use with Power Macintosh and with other Mac OS-based personal computers
which utilize the PCI local bus. This card includes two ports which support
T1 data rates as well as numerous serial interfaces including RS-232,
RS-422, RS-449, RS-485, V.35, and X.21.

Using the SMART SERIAL 6 - T1 Edition
The SMART SERIAL 6 - T1 Edition has been deployed by AILINK, a European
newspaper industry VAR which uses the card to connect to satellite
delivered news feeds. Additionally, the SMART SERIAL 6 - T1 Edition can be
used with Vicom Technology software products to implement robust routing
solutions on a Mac OS server.

Hi-Speed Macintosh servers
The HDLC line driver and synchronous PPP Communications Toolbox tool allow
a whole new class of wide-area networking solutions which can not be
implemented using the modem or printer ports built into a Macintosh.
Possible implementations include synchronous PPP connections supporting
interfaces providing T-1 and Fractional T-1 data transfer rates for
Mac-based web-serving, file transfer, ISP, or satellite-based data
transmission applications.

"In the Windows NT market, it has become very popular to bring T1
connections directly into the server to provide Internet connectivity for
the LAN", noted Neil Kent, Vicom's US Sales and Marketing Manager.
"Keyspan's T1 card and the VICOM Internet Gateway bring this same
capability to Mac OS servers, but bring the added benefit of the Mac's ease
of use. Customers will enjoy high speed, shared Internet access via one IP
address and the single T1 card. And, they'll also appreciate the simplicity
and low cost of this very affordable solution."
