Tim, In addition to the valid questions from Peter, I am also wondering why some additional objects which do not correspond to existing attributes in G.8265.1 are described in this draft (mainly at the end). Among these new objects (which sounds to me like proprietary parameters), one can identify the following ones: ptpOperationalMinTDEVForward OBJECT-TYPE ptpOperationalMinTDEVReverse OBJECT-TYPE ptpOperationalMAFEForward OBJECT-TYPE ptpOperationalMAFEReverse OBJECT-TYPE Are you proposing that a PTP slave compliant with this MIB would have to implement all those objects? Thanks.

Is the MIB dealing with a G.8265.1 Telecom Slave or a G.8265.1 Slave-Only Ordinary Clock Instance or a IEEE1588 Slave Only Ordinary Clock? I am guessing that the intent was a G.8265.1 Telecom Slave but the MIB is missing some of the aspects of this device (e.g. list of grandmasters). Also every object is read-only. Is this the intent or simply that this aspect has not yet been fully developed? I have some additional comments but I want to understand the scope of this MIB first. Peter R.

I have posted the preliminary agenda, based on slot requests received http://www.ietf.org/proceedings/78/agenda/tictoc.txt . I expect that Karen will add some more NTP items before we upload the final agenda. If anyone else is interested in a slot, we still have a bit of spare time (but not much if we want serious discussion over the 1588oMPLS issue). Y(J)S
