[c-nsp] PA-POS-2OC3

[Yasser Aly]

Hi Steinar,

  The URL you pointed out says that PA-POS-2OC3 is 600 bandwidth points.
I am not familiar with the meaning of bandwidth points concept. 

Would you kindly elaborate more or point out a URL explaining the meaning of
bandwidth points.

Regards,
Yasser

Shouldn't be. I believe Cisco's "bandwidth points" reflect reality
fairly well here. PA-POS-2OC3 is 600 bandwidth points according to

http://www.cisco.com/en/US/products/hw/modules/ps2033/products_qanda_item091
86a0080145c44.shtml

so does not oversubscribe one PCI bus (but you can't put anything else
on the same PCI bus if you want to ensure no oversubscription of PCI bus
resources).
