This can only work on a EVC capable box, because it requires mac learning per service instance. You can achieve this if you use a different bridge-domain for each customer vlan though.


On the ME3400E you can rewrite 1:1 with "switchport vlan mapping <vlanid-wire> <vlanid-network>" or dot1Q tunnel with "switchport vlan mapping <c-vlan> dot1q-tunnel <s-vlan>", but you cannot map multiple vlans on the wire to a single vlan on the network (unless you dot1q tunnel, of course).
