I have just uploaded APC-1438 and APC-1439 to the Incoming directory at the Picturetel site. These documents are levant to tomorrow's Gateway decomposition conference call. APC-1438 conveys the Phase 1 and 2 architecture and requirements document, DTS/TIPHON-02002. The architecture shown in this document is agreed, after much discussion. However, the document is still undergoing detailed revision to make sure all of the text is consistent. It is also missing text on information requirements across reference point 'J', which would cover our interfaces 'C' and 'D' (i.e. all switched circuit network signalling). It would help TIPHON move along if we could contribute some suggested text to their list, TIPHON@LIST.ETSI.FR. Any other comments on the document would also be welcome. Specifically in section 6.5 dealing with the device control interface, the tutorial portions of the material I put out on this list the other data are being excised, leaving just the bare statement of requirements. I suggest we continue working from that previous document for the conference call. Two more requirements were noted under "Resource Management": the ability to block and unblock groups of circuits in response to SS7 signals, and the ability to support testlines. APC-1439 conveys a liaison asking for transparent passage of ISUP between Gatekeepers. I'll leave you to read the details, but I think we need to discuss a bit what the best way is to achieve this objective, bearing in mind that we may want transparent passage of other protocols besides ISUP.
