Table SEQ Table \* ARABIC 76 - SCCP replicate mode

Replicate Mode

Description

TB640_SS7_SCCP_ROUTE_REPLICATED_MODE_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.

TB640_SS7_SCCP_ROUTE_REPLICATED_MODE_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.

TB640_SS7_SCCP_ROUTE_REPLICATED_MODE_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.

TB640_SS7_SCCP_ROUTE_REPLICATED_MODE_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.

? Only used with ANSI96 and TLECORDIA.


- The destination point code parameter (Dpc) specifies the point code of the node where the route is terminating. This field is not reconfigurable. Proper point code length is: see Table 3 - DPC Length 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000000E0000005F005200650066003100320034003000360030003200310033000000 .

? Default routing: Note that destination point code 0.0.0 is reserved for default routing. When no explicit route exists for a destination point code and default route 0.0.0 is present, the message is passed to MTP 3 for delivery in place of being dropped. If the MTP 3 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:
