Cost Management
One of the primary objectives in designing NetWAYS/ISDN
was to minimize the ISDN connection costs. NetWAYS/ISDN
uses proven techniques optimized for ISDN to cut connec-
tion costs to the bare minimum. This means that remote ac-
cess is as economical as possible. In “Short-Hold Mode”, the
ISDN connection is cleared down whenever idle. When it is
needed again—that is, when data needs to be transferred—
the ISDN connection is automatically dialed up again. Con-
nection charges thus accrue only for the amount of data
transmitted, not for the duration of a session.
NetWAYS/ISDN automatically detects the billing rate for the
current time of day and can adjust the inactivity timer ac-
cordingly. This feature is especially significant in reducing
costs, given the complex rate structure of ISDN network oper-
ators. Moreover, NetWAYS/ISDN and AVM’s remote access
servers suppress the network operating system's redundant
overhead data traffic on the ISDN link. This is done using
proven and sophisticated protocol filtering and spoofing
techniques.
NetWAYS/ISDN supports cost allocation. This feature en-
sures that the ISDN connection costs are charged to a
specific end of the connection. For example, the central LAN
may be configured to bear the charges for all connections,
regardless of which site initiates them.
NetWAYS/ISDN gives users control of the connection costs
through monthly use accounting and connection cost bud-
gets.
