Hi Hans,
Please note, 7206VXR has two PCI buses , each supports up to 600Mbps, slot0
,1,3,5 connects to PCI mb1,
slot2,4,6 connects to PCI mb2.
You can look at for all PA required bus bandwidth point (kinda marking
scheme), for atm is 300, for I/O with
1FE is 200, for FE-TX is 200. The max bandwidth point for each PCI bus is
600.
Therefore, you can place two PA-A3 to mb2 (total bandwidth point = 600, max
allowed bandwidth point), and then one PA-A3 to mb1. Since mb1 is included
slot 0, in case it is NPE-300 the bandwidth point on mb1 will become 500.
So, somthing like this:
----------------------------
|5 PA-A3 |6 PA-A3 |
|3 |4 PA-A3 |
|1 |2 |
----------------------------
| 0 NPE-300 |
----------------------------
If you ever want to put another high-speed interface to either PA slot, you
will have an error message of "max bandwidth exceed" on your console. You
can, however, put an extra PA-FE to it and ignore the error message. BUT, I
found if I do that, all the FE ports (PA, or NPE300) will have a serious
level of interface reset..... in whatever traffic rate.
Suppose your ATMs are for incoming and outgoing traffic and not for
"transit", then all the ATMs are pumping data toward the FE on NPE-300. So,
you can imagine it is not an effective configuration.

If I were you, I will not go for 7206vxr since the initial config is already
hitting the max. Neither 7507..... if you don't mind, I will recommend a
Juniper M5 with 2 dual ATM pics and 1 Quad FE pic..... and you still have
one pic slot for expansion.
I am not associated with Juniper Networks in any way.... it is just my
thought about Cisco 7206vxr series.
