Hi
Hope this will provide you with the info needed.
The Optical Services Modules (OSMs) for the Cisco 7600 and Cisco Catalyst 6500 Series require the Supervisor Engine 2 with MSFC 2 running 12.1(11b)E.
MPLS/VPNs implemented on the Cisco Catalyst 6500 or Cisco 7600 require both the ingress and egress line cards to be OSMs and/or FlexWAN modules.
Summary:
You will need a SUP2 with MSFC2 and the above mentioned S/W and also a FlexWAN card part no: WS-X6182-2PA with appropriate PA
