My telco company for decreasing the cost offered me some PRI links. The problem is that i have on my routers only BRI interfaces. I installed and configured the BRI interfaces and connected with the PRI links. It looks to work fine. When i use Cisco Works to see the network i realise that those links are no appear, or they are in red color(than blue) or show different bandwidth.
Is there is a problem using BRI interfaces for PRI links? Shall i change the interfaces to PRI.
