the European office. Your Norstar system has a leased line to Europe with
reduced transatlantic charges. You provide that sales representative with a
Class of Service password that gives access to the transatlantic line. The
sales representative can then telephone into the Norstar system from a
hotel, enter their Class of Service password, and use the leased transatlantic
line to make calls.
Remote users can access Norstar lines, line pools, the page feature, and
remote administration (if enabled through Software Keys). The exact
facilities available to you through remote access vary depending on how
your installer or customer service representative set up your system.

a call automatically and wait for a DISA internal number, callers hear a

are allowed into the system.

the line, and the remote package restricts the use of line pools and the page
Remote users can make long distance calls.
Remember that a remote user can make long
distance calls that are charged to your company and
can make page announcements in your office.
