Service State
This field represents the operational state of the packet bus. A service
state of “in” means the packet bus has been installed and is in normal
operation. A service state of “out” means either that the:
■ Packet bus is out of service and has failed certain maintenance tests
■ Maintenance object has been demand busied out.
A service state of “reconfig” means that the Maintenance/Test circuit pack
has swapped one or more signal leads because of lead faults detected
during testing (high- and critical-reliability systems). A service state of
“open lds” means the Maintenance/Test circuit pack query was run, and
open bus leads were found. A service state of blanks in this field means
the system does not have the Packet Bus feature optioned.
When Control Links are down, service state information is unavailable.
Major Alarms
Whether major alarms are logged against the packet bus that is being
displayed (y or n).
When Control Links are down, this field is blank.
Minor Alarms
Whether minor alarms are logged against the packet bus that is being
displayed (y or n).
When Control Links are down, this field is blank.
Bus Faults
This field indicates the number of faulty bus leads, where a fault is defined
as either shorted to another lead or stuck at some value. This field may
take on any integer value between 0 and 24. The field contains a blank if
the Maintenance/Test circuit pack is not present or has been taken out of
service.
When Control Links are down, this field is blank.
Open Bus Leads
This field indicates the number of bus leads that have an open circuit
between the Maintenance/Test circuit pack and bus terminator. This
information is determined by testing performed on the bus leads; bus leads
test open as a result of physical damage to the backplane or the
backplane’s connectors, or because a bus terminator is missing. This field
may contain integer values between 0 and 24. This field contains a blank if
the Maintenance/Test circuit pack is not present or has been taken out of
service.
When Control Links are down, this field is blank.
