DUPINT (Duplication Interface Circuit
Pack)
The Duplication Interface (DUPINT) maintenance object tests the active UN330B
Duplication Interface circuit pack. Tests that fail are recorded in the error and
alarm log as errors/alarms against the active Duplication Interface circuit pack.
No errors/alarms are recorded against the standby Duplication Interface circuit
pack by this maintenance object.
Three Maintenance Objects are utilized in the maintenance of the Duplication
Interface circuit pack and their cabling. These are DUPINT, DUP-CHL, and
SPE-SELE. The first of these, DUPINT, is composed of tests that check the
operation of the active Duplication Interface circuit pack. The second
maintenance object, DUP-CHL, test overall functionality of the circuit pack. This
requires both circuit pack, their cabling, and communication with the standby
software. The third and final MO is SPE-SELE. SPE-SELE monitors the position of
the select switches located on the front of the Duplication Interface circuit pack.
Testing is directional from the active Duplication Interface circuit pack to the
standby Duplication Interface circuit pack. If an interchange has occurred with
alarms raised against DUPINT or DUP-CHL, testing cannot resolve or clear these
alarms because they are against the wrong circuit pack in the active to standby
directional configuration. An interchange is needed to allow testing to resolve or
clear these directional alarms.
Duplication Interface Maintenance Operation
There are six tests that comprise DUPINT. The not-destructive Active DUPINT
HFAIL test is run as scheduled, periodic and demand short. The Active DUPINT
Reset test is the destructive version of the HFAIL test and is only run at
initialization time and on demand long. They are not run as part of periodic or
scheduled maintenance. Test failures or in-line errors for this maintenance object
are logged against the active Duplication Interface circuit pack.
The five destructive tests run by DUPINT are only run during initialization (reset
system 2 or worse) and on demand with the command line of test
duplication-interface long. The clear option is needed to clear alarms for error
types that don’t have an associated test when all of the tests pass or abort. Since
these tests require the turning on and off of memory shadowing, you must enter
the command busyout spe before the long sequence may be run. The busying
out of the SPE turns off memory shadowing but handshaking continues between
