Initializing the System

This section outlines the procedure for administering initial system translations (that is, for initializing) the system).

To initialize the system, you must know the desired configuration. The System 25 implementation forms contain all the information necessary to initialize the system; they also form the basis for system Administration Records. These forms should be properly organized in the Administration Records Binder.

As the system is initialized, it is essential that you write all port assignments on the forms as the ports are translated. Failure to do this will make future changes and additions very difficult.

The steps outlined in the Initialization Sequence below should be followed in the sequence indicated to set up the system. Difficulties may arise if this sequence is not followed.

Default Translations

Two types of cold starts are possible with System 25, which differ in the extent of their default assignments. A “full default” cold start is usually reserved for an extreme system disruption, such as might result from a damaged system translation tape or from replacing a memory board.

The other type of cold start is a “limited default” cold start. It assigns only system defaults (from menu 4) to the system, leaving port assignments (menu 1) blank. This type of cold start may be particularly useful during system initialization, if the dial plan you want to administer is greatly different from the one System 25 assigns in a full-default cold start. The next two sections describe these cold starts in more detail. For specific cold start procedures, see Action=20 under Administering Tape Save/Restore Operations.

Full-Default Cold Start

With a full-default cold start, System 25 assigns default dial codes and trunk numbers as shown in Table 3-1. As you attempt to assign dial codes to stations and trunks following the steps outlined in the next chapter, you may encounter error messages indicating that the numbers/codes you are trying to assign are already assigned. It may be that the default numbering plan conflicts with the one you are implementing. If this happens, change the conflicting default code by first removing the present dial code, then replacing it with the one you want.
