cisco AS5400 - help

[Betmen]

Hi,

So i have this cisco AS5400, and on him there are interconnections towards different locations, they are connected on E1 interfaces.

I want to make graph for active calls for each E1 interface, and one final graph that sums all calls in different graph.

I have found some of the templates, but i cant make it work the way i want.

The problem is, i make 7 different Data Templates with different OID-s and put them in one Graph Template.
I assign this Graph on single E1 and he draws 7 different active calls graphs.
When i make another graph for different E1 interface he draws exactly the same graphs.

So i guess, this OID-s draw complete traffic on AS5400.
So i don't know what is the exact number of active calls on what interface, and how do i make cacti draw this?

anyone can help out?
