X.COMM has built a complimentary
portfolio of products that use inexpensive Async Modems or
ISDN Terminal Adapters (TA's) to connect remote users to the
corporate network and all of the services it provides. Some
are protocol independent and can operate with all Network
Operating Systems while others are Novell specific.
The Async products can operate with V.34 Modems at 28.8Kbps
plus compression or use ISDN TA's at speeds up to 115.2Kbps.
The ISDN specific products operate at 64Kbps and incorporate
a feature called Short Hold Mode. With this the ISDN line
can be dropped during periods of inactivity and transparently
reconnected when there is data to send. While the physical
link is down the server will 'spoof' the application heartbeats
to maintain the logical sessions throughout.
