Remote MTP3 Users

An Remote MTP3 User (RMU) represents a remote SCCP subsystem to which the Signaling Network Interface forwards signaling. When a message is forwarded from an Mobile Switching Center (MSC) to an SS7-MP node, an RMU must be configured for the subsystem on the SS7-MP node.

There are two configuration scenarios for remote subsystems to which only service messages are sent. A service message is a failure indication such as UDTS and XUDTS.

If an RMU exists, the subsystem status is tracked and used for routing SS7 messages (including service messages).

STPs generally do not have subsystems and therefore do not need RMUs. An exception would be an application such as LNP (Local Number Portability) that can be hosted on an STP.

The SS7/Sigtran > Configuration > Remote MTP3 Users GUI page displays an entry for each MTP3 user to which SS7 SCCP signaling is sent, or for which status tracking is desired. The fields are used to populate the Called Party Address parameters.

On the SS7/Sigtran > Configuration > Remote MTP3 Users page, you can perform the following actions:
  • The Filter allows the user to only display the row(s) that match specified criteria using the list that contains the field names. The next right list contains all the matching operators (=, !=, >, >=, <, <=, Like and Is Null). The text box is the value selector used to enter the matching value. Click GO to enable the filter. The RESET button resets the filter.
  • Sort the list entries in ascending or descending order by SS7 Domain, Remote Point Code, Remote SSN, or Remote MTP3 User Name by clicking the column heading.
  • Click Insert.

    You can add a new Remote MTP3 User and its values. See Inserting a Remote MTP3 User.

    If the maximum number of Remote MTP3 Users already exists in the system, the SS7/Sigtran > Configuration > Remote MTP3 Users [Insert] page displays an error message.

  • Select the Remote MTP3 User from the list and click Delete to remove the selected Remote MTP3 User. See Deleting a Remote MTP3 User.
  • Select the Remote MTP3 User from the list and click Status to view the status of the configured Remote MTP3 Users on the SS7/Sigtran > Configuration > Remote MTP3 Users page. See Status of a Remote MTP3 User.
