PRI and BRI

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.

Thanks

Moses,

Honestly I can't imagine how the BRI interfaces can operate when PRI line connected.

We are talking two totally different things in this case (different clocking, framing etc.) only the physical interface can be the same (RJ-45 if unbalanced PRI used).

If PRI is provided then you definitely need PRI interface.

Even I'm surprised, please could you share the router config with us.

Kind Regards,
