| Description |
|---|
| Requirement: The IAO will ensure that all SS7 Links are clearly identified and redundant links are diversely routed from termination point to termination point.The A links that connect an SSP to the STPs need to be clearly identified and routed diversely throughout the switching facility. The A links will take separate routes from termination point to termination point. The termination blocks of the A links should be clearly identified at the MDF. The routes should not cross each other. If the routes need to cross each other, they should cross at 90-degree angles. These precautions will limit possible service degradations to the SS7 network by making service personnel aware of their location and ensure that the switching facility is not isolated from the DSN network. |
