States information, which can be gathered at any time by MTP3, indicates the current state of the software or Service Access Point (SAP). This information indicates the Quality of Service (QoS) parameters and can be used to assist in SS7 software debugging. The collection of status information does not affect any of the information examined.

== Link states ==
General explanation of the link states parameters:

*The '''Link state''' parameter indicates the current state of a MTP3 link. Possible values:

*The '''Locally inhibited''' flag indicates whether or not the link is locally inhibited. Possible values are 'True' or 'False'.
*The '''Remotely inhibited''' flag indicates whether or not the link is remotely inhibited. Possible values are True' or 'False'.
*The '''Locally blocked''' flag indicates whether or not the link is locally blocked. Possible values are True' or 'False'.
*The '''Remotely blocked''' flag indicates whether or not the link is remotely blocked. Possible values are True' or 'False'.
*The '''Congested''' flag indicates whether or not the link is in congestion state. Possible values are True' or 'False'.
*The '''Emergency indication''' flag indicates we are in emergency condition. Possible values are True' or 'False'.
*The '''Retransmit queue size''' field gives the number of messages presents in link retransmit queue. Messages in retransmit queue are present only for a short duration until the buffer retrieval is completed during the changeover procedure.
*The '''Transmit queue size''' field gives the number of messages queued in the link transmit queue.
*The '''Congestion priority''' field. Allowable values: see Table 19 - MTP3 link prioritiesTable 23 - MTP3 link priorities.

The current congestion status is updated based on the configured thresholds hit in the link transmit queue after queuing is initiated. For international networks and networks without multiple congestion states (where all un32PrioXMsgQueueLe are same), the CongestionPriority can take only two values: 'Priority 3' (link congested) or 'Priority 0' (no congestion).
