Component States
A status report for the media gateway lists both the administrative state and operational state of the link
to the media gateway as well as the operational state of the gateway.
This section explains how to use status, control, and administrative commands to determine the status of
various solution components, including:
• Signaling Gateway Process
• Signaling Destinations
• Destination Point Code Status
• Aggregation Status
• Media Gateway
• Subscriber Termination
• Trunk Group
• Trunk Termination
Signaling Gateway Process
The status command for the signaling gateway process (SGP) returns the state of the SGP.
CLI> status sgp-id=sgp1;
where sgp-id is the ID of the selected signaling gateway process.
Signaling Destinations
Signaling destinations are endpoints in a time-division multiplex (TDM) network. In SS7, multiple
destinations can be served by one or more signaling links. Destination states are similar to the signaling
link states, but with fewer possible combinations.
Table 3-1 identifies and defines the possible signaling destination states:
Table 3-1 Signaling Destination States
Destination State ID Name Definition
IS In Service Ideal state—Generally, if signaling links are in
service, destinations should be in service as well.
OOS Out-of-Service Link is unavailable, often due to a communication
problem with the remote end. Requires additional
diagnosis.
INB Installed Busy Default state of newly installed links. New links must
be manually set in service using the set-sc-state
command.
