displays on the telephone's LCD. This allows the user to identify the caller before answer-
ing.
The DNIS Name/Number routes calls to specific telephones, departments, or ACD
groups. When the call is ringing and after it is answered, the DNIS Name/Number dis-
plays on the telephone's LCD. The name and number display can also be sent to an agent
computer to be used by a CTI application.
DNIS use cases include sending DNIS calls to a group of agents that take orders for a
number of different companies and products. The agents know how to answer the calls
from the DNIS display. Using DNIS allows one group of lines to serve multiple applica-
tions. DNIS service is provided by DID, T1 (via a gateway), or ISDN trunk (via a gate-
way) interfaces and provides the same call routing options and destinations as DID calls.

Directory Numbers

A Directory Number DN, sometimes called an "extension number," is the number some-
one must call to reach a destination within the system. Each DN is assigned as the main
directory number of a telephone. To maximize call coverage flexibility any DN can appear
on multiple telephones. Also, individual telephones can have multiple DN buttons with
different Directory Numbers.
The system provides Primary and Phantom DN buttons on telephones. All DN buttons can
be used to originate and answer calls.
Primary DN Buttons
Primary Directory Number buttons PDNs are needed to make and receive calls. It is a tele-
phone's main extension number. Each telephone is assigned only one PDN and that tele-
phone is designated as the owner of the PDN. This PDN button can be made to appear
multiple times on other telephones (see Secondary DN Buttons). Features, Class of Ser-
vice, etc., are associated only with the station assigned as the owner of the PDN. PDNs
that appear on telephones other than the owner telephone are referred to as Secondary
DNs or SDNs.
Phantom DN Buttons
Phantom DN buttons PhDNs are additional directory numbers appearing on telephones as
extension buttons. PhDNs can be used as independent extensions on the phone or can
appear on multiple phones to be used to allow call handling for departments or groups of
telephones.
PhDNs can be used to make a telephone appear to have multiple PDN extension buttons.
When assigning a PhDN for use as another appearance of the PDN, the display properties
are set the same as the PDN and a hunting sequence is set up to roll the calls from the PDN
over to the other PhDNs associated with the PDN. With this arrangement, Call Forward
sends calls to the PDN's destinations and Voice Mailbox.
