Sanity monitoring
Sanity monitoring is a background routine that checks the operation of
system resources, such as CPU activity and memory allocation. This
background routine tries to restore normal operation if the system
performance has degraded to an unacceptable level. If all attempts to
restore normal operation fail, this routine restarts the system to restore
operation. If the soft reset is not effective, the system initiates a full,
board-level reset. If the full reset is not successful, the maintenance
LED remains on.
Diagnostic commands
Succession 1000M, Succession 1000, and Meridian 1 overlay
commands
Each card performs diagnostic tests as part of the daily routines.
Diagnostic tests can also be activated from a maintenance TTY.
The boot time of the MICB from reset, or power up, to when the card is
ready and from an ENLC to when the ports are idle is approximately two
minutes.
All relevant system maintenance commands for an extended digital line
card apply to the MICB and are handled transparently to the system.
Use LD 32 to enable and disable an ACD M2616 telephone.
Table 36 lists some of the commands used to control the MICB status
and functions.
