The Directory feature is a built-in, interactive telephone book that stores listings
that include names and telephone or extension numbers and provides
automatic dialing of the numbers to users with MLX display telephones. The
listings are divided into three types of directories:
System. Lists names and numbers of outside contacts (such as clients and
suppliers). These listings are created in system programming and are
assigned System Speed Dial codes to allow users with telephones other than
MLX display telephones to dial the listings in the directory. See "Speed Dial"
in this chapter for details.
Extension. Lists all users in the system and their extensions. These listings
are automatically created, and names are included via system programming
by using the Labeling feature.
Personal. Lists individual users' listings of frequently called people or
businesses and their telephone numbers. Personal Directories are available
only on MLX-20L™ telephones and are accessible only from the telephones
used to create them. Extension numbers can be programmed in a Personal
Directory. However, in the Key and Behind Switch modes, the user must
press an Intercom button before selecting the listing to dial the number.
On MLX display telephones, users can search the directories, select a listing,
and dial the appropriate number with the press of a display button. On all other
types of telephones, users can dial the listings in the System Directory by dialing
the System Speed Dial codes assigned to the listings. However, users must dial
extension numbers to call co-workers—they cannot use the Extension Directory.
A user with an analog multiline telephone or with an MLX-10 telephone cannot
use the Extension Directory feature or the Personal Dlrectory feature but can dial
the listings in the System Directory by dialing the System Speed Dial codes
assigned to the listings.
