Signaling Point Timer Profile

Each Signaling Point Timer Profile object is a child of the Signaling Gateway object.

The Signaling Gateway has associated with it a Signaling Point Timer Profile. The Signaling Point Timer Profile defines the characteristics of the Signaling Gateway. You can delete a Signaling Point Timer Profile only when it is not associated with the Signaling Gateway.

A default Signaling Point Timer Profile named "Default" is supplied with the MetaSwitch NE. The default profile should be suitable for most applications.


The default profile is read-only; you cannot delete, modify, or disable it. If you want to use different values, you must create a new Signaling Point Timer Profile and change the Signaling Gateway to specify the new profile name.

Description
Profile name Change Unique user-friendly name identifying the Signaling Point Timer Profile. Specify a name of up to 30 characters. If a name is not specified, the EMS displays a default.
MTP3 timer T2 Change Inactive ITU Q.704 timer T2. Waiting for changeover acknowledgement. Range: 700 - 2000ms. The default is 1400ms. If this signaling point is to support routes with long propagation delays, a minimum value of 1400ms is recommended.
MTP3 timer T4 Change Inactive ITU Q.704 timer T4. Waiting for changeback acknowledgement (first attempt). Range: 500 - 1200ms. The default is 800ms. If this signaling point is to support routes with long propagation delays, a minimum value of 800ms is recommended.
MTP3 timer T5 Change Inactive ITU Q.704 timer T5. Waiting for changeback acknowledgement (second attempt). Range: 500 - 1200ms. The default is 800ms. If this signaling point is to support routes with long propagation delays, a minimum value of 800ms is recommended.
MTP3 timer T7 Change Inactive ITU Q.704 timer T7. Waiting for signaling data link connection acknowledgement. Range: 1000 - 2000ms. The default is 1500ms.
MTP3 timer T11 Change Inactive ITU Q.704 timer T11. Transfer restricted timer. Range: 30000 - 90000ms. The default is 60000ms.
MTP3 timer T12 Change Inactive ITU Q.704 timer T12. Waiting for uninhibit acknowledgement. Range: 800 - 1500ms. The default is 1200ms.
MTP3 timer T13 Change Inactive ITU Q.704 timer T13. Waiting for force uninhibit. Range: 800 - 1500ms. The default is 1200ms.
MTP3 timer T14 Change Inactive ITU Q.704 timer T14. Waiting for inhibition acknowledgement. Range: 2000 - 3000ms. The default is 2500ms.
MTP3 timer T15 Change Inactive ITU Q.704 timer T15. Waiting to start signaling route set congestion test. Range: 2000 - 3000ms. The default is 2500ms.
MTP3 timer T16 Change Inactive ITU Q.704 timer T16. Waiting for route set congestion status update. Range: 1400 - 2000ms. The default is 1700ms.
MTP3 timer ITU T18 Change Inactive ITU Q.704 timer T18. This is the timer within a signaling point whose MTP restarts, for supervising link and linkset activation as well as the receipt of routing information. The units are milliseconds, and the value is implementation and network dependent. Criteria to choose T18 are given in 9.2/Q.704. Range: 1000 - 45000ms. The default is 2000ms.
MTP3 timer ITU T19 / ANSI T29 Change Inactive ITU Q.704 timer T19 and ANSI T1.111.4 timer T29. Supervision timer during MTP restart to avoid possible ping-pong of TFP, TFR, TRA and TRW messages. Range: 60000 - 69000ms. (For ANSI, the valid range is 60000 - 65000ms.) (For ITU, the valid range is 67000 - 69000ms.)
MTP3 timer ITU T21 Change Inactive ITU Q.704 timer T21. Overall MTP restart timer at a signaling point adjacent to one whose MTP restarts. Range: 1000 - 65000ms. The default is 2000ms to interoperate with back level ('blue book') exchanges.
MTP3 timer ITU T22 / ANSI T20 Change Inactive ITU Q.704 timer T22 and ANSI T1.111.4 timer T20. Local inhibit test timer. Range: 90000 - 360000ms. (For ITU, the valid range is 180000 - 360000ms.) (For ANSI, the valid range is 90000 - 120000ms.)
MTP3 timer ITU T23 / ANSI T21 Change Inactive ITU Q.704 timer T23 and ANSI T1.111.4 timer T21. Remote inhibit test timer. Range: 90000 - 360000ms. (For ITU, the valid range is 180000 - 360000ms.) (For ANSI, the valid range is 90000 - 120000ms.)
MTP3 timer SLT T1 Change Inactive ITU Q.707 timer T1. Range: 4000 - 12000ms. The default is 8000ms.
MTP3 timer SLT T2 Change Inactive ITU Q.707 timer T2. Range: 30000 - 90000ms. The default is 60000ms.
Requested status Read only Specifies whether an administrator has attempted to enable the Signaling Point Timer Profile. Values:
  • Enabled
    The object has been enabled.
  • Disabled
    The object has not been enabled or has been disabled.
Actual status Read only Specifies the current status of the Signaling Point Timer Profile. Values:
  • Enabled
    The object has been enabled.
  • Disabled
    The object has not been enabled or has been disabled.
