stability timer
This timer allows the detection of repetitive main FP card failures and is used
to cause a switchover if a main function processor in a one-for-n sparing
configuration fails within one hour after it starts running as the active FP. See
also
sparing timer (page 125)
standard virtual path terminator
A type of virtual path terminator that allows simultaneous traffic management
at both the VP and VC level. Standard virtual path terminators also allow VPs
and VCs on the same interface to dynamically share bandwidth.
standby
Applies to equipment and instances of software that protect the ability to
provide services through redundancy. Standby equipment and software can
run in a variety of modes. See
cold standby (page 30), hot standby (page 62),
and warm standby (page 148).
state
An operational value indicating the high-level condition of a component. Its
range of values is usually small. For example, the usage state can be idle,
active, or busy, while the amount-used status could vary from 0 percent to 100
percent. State changes can generate alarms or service change notifications.
Status changes can generate alarms when certain thresholds are passed.
state change notification (SCN)
In OSI, a notification of a change of OSI state and status values. In Nortel
Multiservice Switch systems, the notification is generated only by a change in
operational state changes in a preselected set of components. Nortel
Multiservice Data Manager uses SCNs to update the state of components that
are being displayed.
state walk
An activity performed by the Multiservice Data Manager surveillance
infrastructure to obtain or synchronize fault information from a device (for
example, a Nortel Multiservice Switch node).
static_local
A network directly connected to the router in question.
static_remote
A host or route statically defined to the router in question but not directly
connected to the router.
