You may need to configure non-adjacent signaling points. A non-adjacent signaling point is a signaling point that is not directly connected to the MTP 3 layer but is accessible through a signaling point that is directly connected. The following illustration shows this type of configuration:
Follow this procedure to configure a non-adjacent signaling point:
Step |
Action |
1 |
Configure all links, linksets, and routes to adjacent signaling points as described in the sample configuration files. |
2 |
Add a route entry (direction down) for the non-adjacent SP, specifying its point code as the destination of the route. |
3 |
Add the route number for the non-adjacent SP to the linkset entry for each linkset that can be used to reach the non-adjacent destination. |
Since the non-adjacent SP in the illustration (point code 1.1.200) is accessible from both STPs, the route entry for 1.1.200 is added to the linkset definitions for both linksets 1 and 2. Since the STPs are cross connected, the route to each STP is also added to both linksets 1 and 2 since STP 1.1.1 can be reached directly through linkset 2 or indirectly through linkset 1 with STP 1.1.0.
The following example MTP configuration file configures non-adjacent signaling points:
