Do you have the router and the cards, or your is only a hipotetical question ?
Do you refer to voice or data calls ?
In other words, what are yting to do, in reality ?

Hi Paolo,
I'm talking about data calls.. as backup link..
The 7206VXR router is at central site.. Its connected to more than 1500 banch locations.
I've dedicated links to all braches, and now i want to configure backup links of 64kbps to each brach..
PRI links are available.. I can buy any type of cards for 7206VXR..
I want to know what is the maximus calls supprted by my router with any card..
Thanks..

With 6x PA-MC-8TE1+ you should be able to support 1440 calls, theoretically.
What will require NPE-G1 or G2.
However for many good reasons, you shoudl balance the load across multiple routers.

I too was thinking in that way.. but, practically we can't configure more than 4 PRI on the card, i think so.. again whether the router will support it or not.. these are my doubts..

Which exact card do you have as seen from "show diag" ?
06-13-2011 03:24 AM
In any card which have 8 E1/T1 ports.. we can configure only four of them as PRI channels.. the rest can only be configured as a dedicated E1 or T1 line.. i've not checked this.. i've heard this from one engineer.. i want to know the details..

That is true for certain cards and not for others, specifically the one I have mentioned before.
That is why I asked you to mention what you have.
