We used VeEX for a while and had our CO Techs run around with hand-held VeEx testers and run tests from them to a VeEx loopback device.... I config'd mpls pw's between them. We don't really do this anymore... we now role out Accedian MetroNid's and MetroNode's which have a lot of this RFC2544 and Y.1731 (accedian paa) built-in... -Aaron
