Toolpack:Create an SCCP Route
From TBwiki
This step in the Web Portal configuration exists to create a route to a specific destination point code (DPC).
Description of parameters
General explanation of the configuration parameters:
- The Handle SCCP LSAP parameter specifies the handle of the SCCP LSAP
- The Protocol variant parameter specifies the SCCP route protocol variant for this destination point code. Allowable values:
| Route Protocol Variant | Description |
|---|---|
| ANSI 88 | Used for ANSI88 |
| ANSI 92 | Used for ANSI92 |
| ANSI 96 | Used for ANSI96 |
| TELCORDIA | Used for TELCORDIA |
| ITU 88 | Used for ITU88 |
| ITU 92 | Used for ITU92 |
| ITU 96 | Used for ITU96 |
| GSM 0806 | Valid in both ITU and ANSI networks |
- The SCCP Replicate mode parameter specifies the mode of replicated nodes/subsystems. Allowable values:
| Replicate mode | Description |
|---|---|
| Dominant | In this mode, each backup node/subsystem is assigned a unique priority. The node/subsystem on this route is the primary node/subsystem and is selected as the preferred node/subsystem when accessible. On failure of the preferred node/subsystem the next higher priority available backup node/subsystem is selected as the preferred node/subsystem. |
| Loadshare | In this mode, each backup node/subsystem together with the node/subsystem configured on the route is assigned equal priority and load is distributed among nodes/subsystems on the basis of: 1) SLS for class1 traffic, and 2) in round-robin fashion for class 0 traffic. Loadshare mode is applicable in TELCORDIA only. |
| Dominant alternate | This mode is significant only for class 0 traffic. In this mode, class 0 traffic is prevented from reaching an accessible but congested node. For class 1 traffic, this mode is same as DOMINANT mode. In this mode, each backup node/subsystem is assigned a unique priority. The node/subsystem configured on the route is selected as the primary node/subsystem and is the preffered node/subsystem when accessible and not congested. On failure or congestion of the preferred node/subsystem the next higher priority available and uncongested backup node/subsystem is selected as the preferred node/subsystem. This mode of operation is applicable only in ANSI96 and TELCORDIA. |
| Loadshare alternate | This mode is significant only for class 0 traffic. In this mode, class 0 traffic is prevented from reaching an accessible, but congested node. For class 1 traffic, this mode is same as LOADSHARE mode. In this mode, each backup node/subsystem together with the node/subsystem configured on the route is assigned equal priority and load is distributed among nodes/subsystems on the basis of: 1) SLS for class 1 traffic, and 2) in round-robin fashion for class 0 traffic. For class 0 traffic, a node/subsystem is selected when it is accessible and uncongested. On failure or congestion of the node, next available and uncongested node/subsystem is selected. This mode of operation is applicable only in TELCORDIA. |
Note: Only used with ANSI96 and TELCORDIA.
- The Destination point code (DPC) parameter specifies the point code of the node where the route is terminating. Proper point code length is described in MTP2:Point Code Length.
Note: The destination point code 0.0.0 is reserved for default routing. When no explicit route exists for a destination point code and the default route 0.0.0 is present, the message is passed to MTP3 for delivery in place of being dropped. If the MTP3 layer is unable to deliver the message for any reason, the message is dropped and no notification is given to the application that originated the message.
- The Options parameter specifies the route options. Allowable values:
| Route Options | Description |
|---|---|
| None | None (no options) |
| Online by default | Node is online by default |
| Translator node | Translator node |
| Adjacent node | Adjacent node |
| INS capable node | INS capable. Only in TELCORDIA. |
Note: These values can be ORed together.
- The Broadband support flag parameter. Flag to indicate whether the peer SCCP on the route has broadband support. Allowable values are 'True' or 'False'.
Note: For ITU88, ITU92, ANSI88, ANSI92 and ANSI96 network this flag should always be 'False'.
- The Signaling link selector mask parameter specifies, in ANSI and TELCORDIA networks, if the SLS can be either 5 bits or 8 bits. Allowable values:
| Route SLS Mask | Description |
|---|---|
| 5 bits | Networks SLS is 5 bits. |
| 8 bits | Networks SLS is 8 bits |
Note: For ANSI and TELCORDIA only.
- The Number backup point code parameter specifies the number of backup point code entries in the Backup Point Code and Priority Backup Point Code arrays
- The Array of backup point code entries parameter specifies the list of backup point code for this route
- The Array of priority of backup point code entries parameter specifies the list of priority of each backup point code for this route. Allowable values are from 0 to 255.
Note: Zero being the lowest priority
- The Number subsystem number parameter specifies the number of subsystem number entries in the Subsystem Number array
- The Array of subsystem number entries parameter specifies the list of subsystem number for this route
Description of SSN specific parameters

- The Subsystem number parameter specifies a subsystem number for this route. Allowable values are from 1 to 255.
