those facilities in the location that has the lowest calling rates at the particular time
a call is made. You can also use this feature to change the routing patterns when
an office is closed and to eliminate unauthorized calls.
Basic features
The following features come standard with the system.
Abbreviated Dialing
Provides lists of stored numbers users can use to do the following:
■ Place local, long-distance, and international calls.
■ Activate features.
■ Access remote computer equipment.
Users dial the list number and the one-, two-, or three-digit number associated
with the phone number the user wants. The number is then automatically dialed
by the system. A frequently called number can be stored on an abbreviated
dialing button that a user needs to press once to make the call.
Access Security Gateway
Access Security Gateway is an authentication interface used to secure the system
administration and maintenance ports and/or logins on the system. Access
Security Gateway employs a challenge/response protocol to confirm the validity of
a user and reduce the opportunity for unauthorized access. Successful
authentication is accomplished when the feature communicates with a compatible
key. The challenge/response negotiation is initiated once an RS-232 session is
established and a valid system login ID has been supplied by a user. The
authentication transaction consists of a challenge, issued by the system and
based on the login ID supplied by the user, followed by receipt of the expected
response, which is supplied by the user.
Active Dialing
The 6400-series telephones have a dialing option that allows the set to send
S-channel button codes when the user presses a number on the dial pad while
on-hook. This allows the user to begin dialing without first going off-hook.
