372 Defining the System DN headingsN0008589 3.3You can also renumber a group of DNs after you initialize your system. For example, if yourservice provider has given you a specific list of DID numbers, you might choose to ensure theDNs mirror those numbers, to make it easier to administer the telephones. The DN RenumberWizard allows you to accomplish this quickly. Refer to “Using a wizard to renumbertelephone DNs” on page 378. If you do this after you have programmed telephones to theDNs, the programming attached to the original DN is transferred to the new DN and the newDN record displays the new port number.The exception to this is the DECT DNs. If you change DNs in the range you specified for yourlegacy DECT handsets, you must rerun the DECT Configuration Wizard to reset the DNs onthe DECT module.To view your system settings: Click on Diagnostics, MSC, then select Configuration andclick on System Startup. This screen displays the telephony template that is active for yoursystem and the start DN that is assigned to the system.2 The second part of a DN is the content of the DN record. Each DN heading provides a numberof parameters that get assigned to the telephone that accesses that DN. Some of theseparameters can be copied to other telephones, while others, such as the name of the telephone,and button programming, is unique to each DN record or to each type of telephone.DN content can be updated at any time, such as if you upgrade the model of telephone. Fordetails about setting up or changing a DN record, refer to the sections “Defining the SystemDN headings” on page 370 and “Configuring DNs for system devices” on page 399.Warning: Changing DN settings after system startup:Changes to the Start DN, DN length or Received # length can affect other applications.Make changes to these settings only at system installation, before you do any otherprogramming.
