For the 7600 OSR, its Martini support is Ethernet VLAN. For local customers you could do Ethernet switching. For ATM of FR over MPLS using GSRs or 7500 (I am not sure if both support both) but a Cisco router can do FR switching. Not sure about ATM. In a Riverstone you can do Ethernet switching as well as Martini Ethernet or Ethernet VLAN. In Extreme and Foundry should be similar. By the way, in the case of Juniper I would not say that doing local CCC is a propietary thing, or at least, is as propietary as an ATM switch doing ATM switching, or an Ethernet swicht doing Ethernet switching. .... Each vendor has its limitations of course, and its price :o).
