[c-nsp] Cisso 7600 Sup32 EtherChannel via Ethernet WAN links

[insan praja]

Guys,
my company has just bought some Cisco 7600 Sup32. I'm
trying to connect it via some providers fiber optic
backbone links. Problem is, this provider provides
links on E1-basis, that is, they gave me ethernet
links, but they run it into E1 encapsulation (am I
right?) can I still have my L2 encapsulation and
maybe, MPLS header intact in the other end?
Thanks
