374 Defining the System DN headings
N0008589 3.3
Set DNs
This list displays the 7XXX digital phones, 7406 cordless digital phone,
20XX IP telephones and WLAN IP telephone DNs that are not assigned
or are not active. Use this list to set up new telephones before they are
installed in the field.
Note: If IP telephones are set to auto-assign DNs, the system will select
DNs that are not likely to be required by installed station modules. You
cannot pre-configure the records since you cannot know which DNs the
system will assign to which IP telephone. Once the IP telephone is
configured, the DN record moves to the active list, and you can access it
from this list to perform the required configurations.
Companion DNs
This list displays the DNs for legacy Companion systems. The records on
this list do not have registered handsets.
All Inactive DNs
This list displays all digital and Companion DNs that are not assigned or
are not active.
All ISDN/DECT DNs
This list displays all the DNs that default to ISDN or DECT applications,
plus any DNs from the Companion range that have been changed to
ISDN/DECT.
Note: ISDN/DECT DNs can also be used for handsets for the legacy
Companion system that require more than the default number of
Companion DNs. In this case, when you define the ISDN/DECT DN as
Companion, the record disappears off this list and appears on the Active
Companion DNs list.
All System DNs
This list displays all possible DNs, regardless of whether a station module
is configured to activate them or not. This list begins with the Start DN
that was defined when the system was initialized.
All System B2s
This list displays DNs only if your system is set to PDD (partial double
density). If the system is set to FDD, these are the second-level (B2) DNs
that assign to DS30 bus 06 and 07. This is a read-only list and includes B2
DNs assigned to devices such as legacy Companion handsets. B2 DNs are
also used in some call center applications.
