Chapter 28 Dialing plan: Public network 277Networking Configuration GuidePublic network DN lengthsThe Public network DN length tells the system how long dialing strings will be when entering thenetwork. For example, if you dial 18005551212 the public network DN length for 1, which is 11,tells the system to wait until 11 digits are entered before processing the call.The Public Network DN Lengths/Carrier Codes panel allows you to define DN prefixes and definethe length of the prefixes for public dialing. Figure 87 illustrates this panel.Figure 87 Public Network DN Lengths/Carrier Codes panelsPublic networkdialing planNationalLocal(Subscriber)Local dialing plan defines a seven-digit numbering scheme.National dialing plans define an extended number scheme. NorthAmerica is set to 10 digits. However, systems in other countriesmay have a variable length.Public network code <1 to 7 digits> This number concatenates with the Public OLI, which, by default,is the DN of the device.Note: In systems running the North American profile, if the PublicOLI contains the public network code, that entry overrides anyentry in this field. Refer to “Line Access tab” in the DeviceConfiguration Guide (NN40020-300).Note: If the values for Public Network DN length are set too short, digits willbe stripped from the dialing string. Conversely, if the values are set too large,the dialing will take longer to process.Table 52 Private and Public received numbers (Sheet 2 of 2)Attribute Value Description
