Processor must write through to get access to leads controlled by the Duplication
Interface circuit pack (Tone-Clock Select Lead, 80286 Processor circuit pack
Select Leads, etc.). This maze circuitry ensures that the processor on the
Duplication Interface circuit pack is sane before any of these leads are changed.
The Duplication Interface processor is instructed to write bit patterns through the
maze circuit. The Duplication Interface processor examines the output of the
maze circuit and compares it with the input.
Inter-Duplication Interface Circuit Pack Loop
Back Test (#280)
This test loops back data through the UART used to communicate with the other
Duplication Interface circuit pack. The data is generated by the Duplication
Interface circuit pack processor and is looped through the UART. The test is

Result Description/Recommendation
1000 ABORT System resources required to run this test are not available.
2000 ABORT Response to the test request was not received within the allowable time
period.
2033 ABORT Internal system error
1. Retry the command at 1-minute intervals a maximum of 5 times.
FAIL The Sanity Maze Circuit or the processor on the Duplication Interface circuit
pack is defective, which implies the Duplication Interface circuit pack can
no longer be relied upon to control and support a High or Critical Reliability
system. The Duplication Interface circuit pack needs to be replaced.
1. Follow general procedures for replacing Common Control circuit packs
and replace the Duplication Interface circuit pack.
2. Rerun the test.
NO
BOARD
The Duplication Interface circuit pack has failed to handshake with either
the active Maintenance/Tape Processor (in the case of Duplication
Interface circuit pack A) or with Duplication Interface circuit pack A (in the
case of Duplication Interface circuit pack B).
1. Refer to NO BOARD description for the Duplication Interface Circuit
Pack Status Query Test (#315).
PASS The Duplication Interface circuit pack Sanity Maze is good. This implies
that Duplication Interface circuit pack can correctly control the SPE Select
and Tone-Clock Lead.
