Programs used in Midnight and Background Routines
Overlay Loader
This program locates, loads, and checks software programs. It automatically
activates the Midnight and Background Routines. You can load programs
manually by entering commands through the system terminal or maintenance
telephone. Once the program is loaded, you see the program mnemonic (such
as TRK for Trunk Diagnostic) on the system terminal.
Overload Monitor
The volume of system messages is continuously monitored by the system. If
too many error messages are detected from a line or trunk card, the system
activates the Overload Monitor program. The Overload Monitor disables the
faulty card and generates system messages with the mnemonic OVD.
Resident Trunk Diagnostic
This program automatically monitors all trunk calls and records apparent
faults on each trunk. If the number of faults on a trunk exceeds the threshold
for that trunk, the program generates a system message identifying the trunk
and the type of fault.
