SPE-Down Command Interface
A limited command interface called the SPE-down interface can be used to 
communicate with low level firmware when system software is unavailable for 
executing the usual maintenance commands. This is useful in three situations.
nThe SPE is down in a system without duplicated SPEs
nThe...

SPE-Down Mode
Severe problems with components of the SPE may render a non-duplicated 
system incapable of call processing and other normal operations. When this 
happens, the system enters SPE-down mode and software is no longer in control. 
If the SPE is duplicated, this situation only occurs when 
both SPEs have...

You can now enter SPE-down interface commands as described in ‘‘Using the 
SPE-Down Interface’’. If the prompt does not appear, check the connections 
between the terminal and the control carrier. Make sure the cable is connected to 
the connector labeled 
ACTIVE. If possible, try a different cable and/or terminal. If...

To return the standby SPE to service, see the following section on ‘‘Bringing the 
SPE Back into Service’’.
NOTE:
The physical connection of the terminal to the STANDBY connector while 
the SPE is locked standby with the SPE-Select switches prevents the 
Standby Maintenance Monitor (SMM) from running. Any reboot...

The following qualifier can be used with the test commands:
Enter 
only the characters which appear in bold type. For instance, to test all 
memory boards ten times, enter t ma 10 Entering t results in testing all boards 
once. You can abort the execution of a command by pressing 
ESC 3 times.

performs exhaustive tests and can be very time-consuming.
When testing is complete, the system readies itself for another command and the 
prompt appears. If testing does not...

Bringing the SPE Back into Service
!WARNING:
In a system with duplicated SPEs, a spontaneous SPE interchange may 
occur if the active SPE is not in good health and either
— an unlocked SPE completes its reboot and handshake is 
reestablished
— a locked SPE in which the Standby Maintenance Monitor (SMM) is 
running is...

2. As soon as initialization diagnostics begin to appear on the screen, 
disconnect the MT cable from the STANDBY connector on the control 
carrier.
3. Return the SPE-SELECT switches to their previous locked position.
When the standby is back up and cycling, the yellow LED on the Processor 
circuit pack will begin...
