Hi, Have there been any definitions for the SENDER_TSPEC object for pure light, i.e. for an all-optical switch that is transparent to SONET/GigE, etc? (Since it is a required object in the path message). Or should the object defined in the intserv document (rfc2210) be used, despite the fact that most of it is useless for this case?
