Defining the System DN headings 371
Programming Operations Guide
The System DN heading provides access to the DN records of telephones that are active on the
system, records of all the DNs that are available, and a comprehensive list of all DN possibilities.
Use the list that is most convenient for what you want to do.
Figure 117 System DNs main headings
The two sides of a DN record
There are two sides to DNs that affect system telephones and equipment.
1
On the system side, each telephone or telephony-based device on the network is assigned a DN
number, which identifies it to the system. DNs for digital telephones map to each wire pair on
a station media bay module, this includes the 7XXX digital phones.
ISDN, and the legacy DECT, and Companion systems also require media bay modules to
operate. However, they have a specific set of DNs that are not mapped directly to the
hardware. Refer to table entry:
Active Companion DNs on page 373 and table entry: All ISDN/
DECT DNs on page 374.
The 20XX IP telephones and the WLAN IP telephones do not use media bay modules because
their connections occur over the internet and directly through the Media Services Card (MSC)
within the Business Communications Manager hardware. However, the system uses DN
records from the digital range to identify these telephones because their functionality closely
mirrors the digital telephones.
As well, certain applications running on the Business Communications Manager are assigned
DNs, so that the system can access the application functionality. These would include direct
inward access (DISA) DNs, and DNs for CallPilot access. Refer to table entry:
Active
application DNs on page 373.
When you initialize your system with the Quick Start Wizard, you will be asked to specify a
DN length and a Start DN.
