MULTIFUNCTION
BUTTONS Multifunction buttons have three uses:
One-touch: Dial a stored number.
Network Feature: Activate or deactivate a special
network feature, such as call forwarding.
Call Appearance (CA) or Directory Number (DN):
Handles incoming or outgoing calls.
Use and set-up of the multi-function buttons is
covered in Chapters 2 and 3 respectively.
Special features such as call forwarding are provided
by the ISDN network. These features are selected
by your System Administrator and assigned to
buttons on your phone during installation.
Appendix C describes frequently used
assignments and ordering codes for
NI.
Each digital set associates its primary DN with
multifunction button 1. Multiple appearances of
the same DN are always on adjacent CA buttons.
(The button at the end of a row is “adjacent to” the
button beginning the next row up.)
Note: This guide uses the term directory number
appearances to refer to telephone numbers
that appear on more than one CA button.
The Nortel term for CAs that can handle more
than one call is Additional Functional Calls.
A telephone can also be assigned additional
DNs. Each such number can then be assigned
to adjacent buttons as well to allow multiple
call handling on that line.
Any DN assigned to one phone can also appear
on another phone, which can then share the use
of that line.
Figure 1-8 shows a digital set whose primary DN is
747-3456, with two additional CA buttons assigned
that same number. The telephone’s secondary line
is 747-7890, which has two appearances.
