[c-nsp] ATM LC on GSR

[Yinglam Cheung]

I have a couple of questions for ATM LC on GSR.

1. there are two quad OC3 ATM line cards: 4OC3/ATM-MM-SC and
4OC3X/ATM-MM-SC. The extra X is for ISE LC.
In terms of AToM features, is there any difference on latest IOS
12.0(32)S? My concern is that the older one may not have all features. 

2. is there any hardware revision trick like in PA-A3-OC3 in 7200?
PA-A3-OC3 requires revision higher than 1.2 to support AToM.

3. what's the max number of ATM VC on these two types of line cards?
"show interface" on my 7206VXR shows the max # of VCs.

Maybe this question is too far. Is Cisco going to support PPPoA and
PPPoEoA features on GSR? It's nice to see 12.2(28)SB has broadband
features now on 7200vxr.
