Limited Default Cold Start
If you have many conflicting default codes, you may want to perform a limited default cold
start. This type of cold start does not assign a numbering plan to the system, except for the
800-series numbers and the ARS code listed in Table 3-1. Since the system does not assign
defaults for stations and trunks, it is easier for you to assign numerous new dial codes, since
you don’t have to remove default-assigned dial codes before you can add the new codes.
A limited default cold start does assign most of the system defaults from menu 4, except the
modem request code and CO trunk pool access code.
You need to reassign those codes after
a limited default cold start. (See Action=60 and Action=
71 in Administering System-Wide
Options.)
Unassigned Trunk Ports
It is also important to untranslate (or remove) any unassigned trunk ports on System 25. To
untranslated, follow the procedure for removing a trunk.
This tells the system that no facility
is assigned to that port.
Since outgoing trunk selection of pooled facilities is made in reverse
order of trunk assignment (last assigned is first selected), default assigned trunks that are not
actually connected to incoming facilities will result in the selection of unconnected port
circuits for outgoing calls. System users will receive a reorder tone when trying to access
such ports. The circuit pack will display a red alarm LED and the attendant console will
display a green alarm LED. Then you will have to untranslate the port.
