Nautica 200 Installation Guide
If your computer is locally attached to a mail server, it may be
appropriate to poll for e-mail every five minutes or less. These
rules change if your computer is remotely connected to a mail
server via an ISDN router. It is not appropriate, for example, to
have the router calling the remote mail server every five minutes
to check for new mail.
To this end, it is recommended that you configure your e-mail
client for manual polling (where you press a button to check for
e-mail), or for a longer polling interval, such as once every hour.
Be aware though, that even with an hourly polling setting, the
router will make one call every hour. If you leave your PC and
router running overnight, this would mean 24 calls every day,
even if you have no new e-mail.
Remotely Mapped Drives
In most popular PC operating systems, it is possible to map
virtual drives (such as J:) to file servers on the network. If you
map network drives over a remote ISDN connection, problems
can occur.
Every time you open a file, or move into a new folder, it is likely
that the PC may request the current status of all drives and bring
up an ISDN call to achieve this.
For this reason, it is recommended that you do not permanently
map network drives over a remote ISDN connection.
Similarly, if you browse the network over a remote ISDN
connection you will incur ISDN call charges.
File and Print Sharing
Many workgroup functions, designed to allow resource sharing
on a local network, use a periodic announcement/update
mechanism which causes frequent ISDN calls if used over a
remote ISDN connection. In order to avoid this, it is
recommended that you turn off file and print sharing on your PC.
