You can provide security for the system by requiring that people using Remote
Access dial a password or barrier code to call into the system. When barrier
codes are required, the caller dials a 4-digit number after the Remote Access
special dial tone and then hears the system dial tone.
CAUTION
Under applicable tariffs, the customer is responsible for any charges
incurred through the remote use of system facilities. Precautions should be
taken to prevent unauthorized use of the system's outside lines by remote
callers, also called "toll fraud." See "Customer Support lnformation" at the
front of this book for more information on security.
You must decide which lines you want to be used for either Dedicated or Shared
Remote Access:
When you assign Dedicated Remote Access to a line, all calls coming in on
that line receive the Remote Access treatment. This means that the caller
hears the system dial tone if no barrier codes are setup for the line, or a
special dial tone if you specify that a barrier code is needed.
When you assign Shared Remote Access, calls coming in on that line receive
the Remote Access treatment only when the system is in Night Service (see
Chapter 4).
You can assign Remote Access to any outside line connected to the system
except dial-in tie trunks. For dial-in tie trunks, Remote Access is achieved by
dialing the factory-set Remote Access code, 889.
You may want to begin by assigning Remote Access to only a few lines and
increasing the number later if more are needed. Keep in mind that Remote
Access should not be assigned to lines and tie trunks that are used for incoming
customer calls.
Once you have decided which lines are to be used for Remote Access, decide
whether you want to change the factory-set access number from 889 for dial-in
tie trunk.
