h. This error indicates that the link has experienced slow transmit rate due to
unknown causes, meaning that the endpoint location may experience
slower throughput rate and the Packet Interface may experience backup
or congestion. The system link is alarmed if 4 or more errors of this type
are detected within 10 min.

System Technician-Demanded Tests: Descriptions
and Error Codes
Testing for system links is different from the standard test procedures for
Maintenance Objects. In addition to testing the system link maintenance object,
the user is allowed to test all the components in the path of the system link. There
are two paths preserved for the link. The current path, if present, represents the
path traversed by the link currently. This path is not present when the link is
down. The other path, the faulted path, is present if the link has ever gone down
or never come up. If the link came up and went down, then the faulted path is
marked
present
. If the link never came up, the faulted path is marked
Defaul
t.
In either case, it represents the path on which the link was attempted or
established unsuccessfully.
Test command for the system links,
test sys-link UUCSSpp
can be specified
with current or faulted as an optional argument if the user wishes to test all the
components in the specified path. The tests executed will be the same if the user
were to test each component manually. In the event that the user does not
specify any path, then only the tests specified for the system links are executed.
System Link Status (#985)
This test is non-destructive. This test queries the switch for the status of the
system link and verifies that all switch components have the same view of the link
state.
