Each Signaling Link Timer Profile object is a child of the Signaling Gateway object.
Each Signaling Link has associated with it a Signaling Link Timer Profile. The Signaling Link Timer Profile defines characteristics of the signaling link with which it is associated. Each Signaling Link Timer Profile can be associated to multiple Signaling Links. A Signaling Link Timer Profile can be deleted only when it is not associated with any Signaling Links.
A default Signaling Link Timer Profile named "Default" is included with each Signaling Gateway supplied with the MetaSwitch NE, and is added automatically to each new Signaling Gateway you create. 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 Link Timer Profile and change the Signaling Link to specify the new profile name. |

Description |
Profile name | Change | Unique user-friendly name identifying the Signaling Link Timer Profile. Specify a name of up to 30 characters. If a name is not specified, the EMS displays a default. |
MTP3 timer T1 | Change Inactive | ITU Q.704 timer T1. Delay to avoid message mis-sequencing on changeover from this link. Range: 500 - 1200ms. The default is 800ms. For routes with long propagation delays, a minimum value of 800ms is recommended. |
MTP3 timer T3 | Change Inactive | ITU Q.704 timer T3. Time controlled diversion-delay to avoid mis-sequencing on changeback from this link. Range: 500 - 1200ms. The default is 800ms. For routes with long propagation delays, a minimum value of 800ms is recommended. The value of this field is network implementation dependent. |
MTP3 timer T17 | Change Inactive | ITU Q.704 timer T17. Delay to avoid oscillation of initial alignment failure and link restart. Range: 800 - 1500ms. The default is 1200ms. The value should be less than the MTP3 timer T2. |
MTP3 timer ANSI T19 | Change Inactive | This field appears only if the parent Signaling Gateway's MTP3 variant is ANSI 1996. ANSI 1.111.4 timer T19. Failed link craft referral timer. Range: 480000 - 600000ms. The default is 540000ms. |
MTP3 timer ITU T24 | Change Inactive | This field does not appear if the parent Signaling Gateway's MTP3 variant is ANSI 1996. ITU Q.704 timer T24. Stabilizing timer after removal of local processor outage, used in LPO latching to RPO (national option). The only valid value is 500ms. |
Requested status | Read only | Specifies whether an administrator has attempted to enable the Signaling Link Timer Profile. Values:
