Sanity Timer; Diagnostics - Nortel Meridian SuperNode SL-100 Reference Manual

6-18 Feature implementation

Sanity timer

Expiration of the sanity timer causes a hard reset of the processor and an
exception report to the XPM, except for cases where diagnostics are executing
on the sanity timer. Message link 0 is channel 0 of DS30 link 0 and message
link 1 is channel 0 for DS30 link 1.

Diagnostics

Upon receipt of an out-of-service test message, the IPE performs a
comprehensive diagnostic test on the controller card circuit pack. The test
results appear on the hexadecimal display (see the "Display functions"
section).
The table that follows presents a list of controller card tests that are a subset of
the power up diagnostics. These tests are used for destructive and
non-destructive out-of-service tests. They may also be called individually by
software.
Note: Test #17 in the following table requires a working DS30A (8-kHz
frame pulse and a 5.12-MHz clock) to be connected to port 0 to pass.
Otherwise, it cannot execute and reports a failed condition.
