Defining Links, Link Sets, and Route Sets
Links identify point-to-point connections of an adjacent node. Link sets are sets of parallel links that can be used for load sharing. Routes identify the final node destination. (The order in which they are defined is important.) Figure 17 provides a simple example of links, link sets, and route sets. In the case of a SIGTRAN installation, the link set most likely consists of a single link because redundancy might not be needed.
You use MML commands to set up links, link sets, and routes to identify the path between Steel-Belted Radius Carrier, the adjacent link, and the final destination (HLR or MSC).
Setting up links, link sets, and route sets involves the MML commands listed in Table 39. For more information about the syntax and usage of the MML commands, see Signalware MML Commands.
Table 39: MML Commands for Defining Links, Link Sets, and Route Sets
Action | MML Command for SS7 Networks | MML Command for SIGTRAN Networks |
|---|---|---|
Identify the local point code and network indicator (NI) | CRTE-OSPC | CRTE-OSPC |
Create a link set and assign it a point code | CRTE-LSET | CREATE-M3UA-LSET |
Create one or more links that belong to the link set | CRTE-SLK | CREATE-M3UA-SLK |
Create a route set that identifies the final destination | CRTE-RSET | CRTE-M3UA-RKEY |
Allow the route set to be used | ALW-RSET | ALW-RSET |
Activate the links | ACTV-SLK | ACTV-SLK |
Example MML Commands
The examples in this section illustrate the MML commands used to create links, link sets, and route sets.
