You can activate an initialization by pressing the manual initialize (Man Int)
button on the NTMW01 SSC card.
An initialization occurs automatically after the System Loader program runs,
when a software or firmware fault is detected, and when a common
equipment hardware fault is detected.
Midnight and Background Routines
In the Configuration Record (LD 17), you can select the nonresident software
programs which will run in the Midnight Routine and Background Routine.
These routines automatically perform maintenance checks. Programs
included in the Midnight Routine are defined with the prompt DROL (derived
from “daily routine overlay”). Programs included in the Background Routine
are defined with the prompt BKGD.
The Midnight Routine runs once every 24 hours. This routine is preset to run
at midnight when a system is shipped, but you may assign a different time in
the Configuration Record. When it is time for the Midnight Routine to start,
the system cancels any other program.
The Background Routine runs when no other program is loaded in the overlay
area. The programs included in the Background Routine run in sequence
repeatedly until there is another request to use the overlay area (for example,
if you log on to check the status of a circuit card) or the Midnight Routine
runs.
You may include the programs listed in Table 58 in Midnight and
Background Routines. Software Audit (LD 44), and Network and Signaling
Diagnostic (LD 30) should always be used in the Background Routine.
