The access method is independent of MPLS, this is one of its large design advantages. You can have legacy T1, T3, etc. on one side, MetroE on the other side, but still have the devices be on the same layer 2 network. This is what MPLS L2VPN (AToM) is designed for. In general MPLS just means that the SP doesn't have to maintain a separate legacy network of native TDM, Frame Relay, and/or ATM, but can still support these and interoperate them with newer access methods such as OCx POS or GigE/10GigE. If in one location they can only offer you T1, it's most likely because of their cable plant. This doesn't mean that you can't connect your other sites with these legacy links though.

Gents - I have this MPLS network provided by this Service Provider, but, they are providing T1 connectivity to various remote sites.
I thought T1 is out of equation and not used any more for site connectivity.
What are the advantages of they providing T1 .. it looks like just the cost and ease.
What other connectivity options do we have? Ethernet etc.
