Midnight And Background Routines - Nortel Meridian 1 General Maintenance Information

Through an initialization, you can download firmware from the CPU to
superloop network cards and controller cards. Call processing is interrupted
for an additional amount of time during this process.
You can activate an initialization by pressing the manual initialize (Man Int)
button on the following:
• NT6D66, NT9D19, NT5D10, or NT5D03 Call Processor Card in
Options 51C, 61C, 81, and 81C
An initialization always occurs automatically after the System Loader
program runs. An initialization often occurs 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 overlay programs
that 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 the Midnight Routine runs or there is another request to use
the overlay area (for example, if you log on to check the status of a circuit
card).
You may include the programs listed in Table 6 in Midnight and Background
Routines. Your maintenance requirements and the configuration of your
system determine the programs you include in Midnight and Background
Routines.
