AT&T 1987 AT&T Telephone User Manual


 
LAST NUMBER DIALED (V2)
Description
Automatically saves the last number dialed from a multiline voice terminal and allows the
user to place the call again without redialing the number.
The feature is administered to a
button on the terminal. Both inside and outside calls can be made in this way. The original
call can be placed by manual dialing, by operation of a programmed button, or by speed
dialing.
To use the feature, the caller first gets dial tone, and then presses the Last Number Dialed
button. The I-use and status LEDs of the button selected for originating the call (for
example, System Access, Loop, or Personal Line) light steadily; if the Last Number Dialed
button has an LED, it lights momentarily. The call proceeds in the normal way. The number
associated with the Last Number Dialed button remains saved even if the called party
answers. Only the dialing of a new number changes the state of the Last Number Dialed
button; the old number is then erased and the new one stored.
Considerations
Last Number Dialed is a convenience feature that is especially valuable for recalling multi-
digit numbers that were first dialed manually from a terminal’s pushbutton dial. However,
the feature can also be used to recall numbers originally called by the following means:
Repertory Dial buttons.
Group Select and DXS buttons on a Selector Console.
This feature saves numbers with up to 16 digits.
The user must hear dial tone before pressing the Last Number Dialed button.
The Last Number Dialed feature cannot be activated by dialing an access code. It is not
available to users of single-line voice terminals.
If a dialed number does not complete a call, Last Number Dialed still stores the digits dialed.
If the user presses the Last Number Dialed button, then dials additional digits to complete
the call, both the currently stored digits and the dialed digits will be stored.
Interactions
Account Code Entry: Last Number Dialed does not save an Account Code dialed by
operation of an Account Code Entry button.
Attendant Display: When a call is placed at a Switched Loop Attendant Console
(V2), using the Last Number Dialed button, the call information display has the
normal format of an outgoing call. In the Inspect mode, pressing the Last Number
Dialed button displays the number currently stored on the button.
Automatic Intercom: Numbers called using an Automatic Intercom button are not
saved by the Last Number Dialed feature. The number currently stored by Last
Number Dialed is not changed by operations of the Automatic Intercom button.
