Re: Hard Copies of Red Bank contributions
by Euchner Martin 23 Sep '99

I'm also a bit concerned about that enormous number of copies to bring in. Do we have some experiences from the Berlin Meeting, how many copies actually have been used? I assume that this number is far below 80. May be 40 is still sufficient. Alternatively, it might be a good idea to print 2 pages on one sheet in order to save trees and reduce weight!

Rich, There is nothing in the latest version of H.245 relating to this. My understanding is that we sent a liaison to SG8 identifying two possible solutions to the problem, and gave them a deadline of 18 October (i.e. The New Jersey meeting) for response. Hopefully the issue can be resolved in NJ and the result included in H.245 V6 in February.

AW: H.450 support
by Karl.Klaghofer＠ICN.SIEMENS.DE 22 Sep '99

22 Sep '99

Alex, The B side that does not support H.450 may just ignore the received supplementary service request. I.e. ROSE at the originating side has to figure out that the other side does not support H.450 (i.e. if no return result, return error or return reject is received from B to a supplementary service request). Although the User-User Information element itself is mandatory, the h4501SupplementaryService apdu is optional. Even in Q.931, sending a STATUS message in case of "optional, unrecognized Information elements received" is just optional. I.e., I recommend not to rely on receiving a STATUS message from the B side in your scenario. In a similar case - in case of optional information element received with contents error - H.323 Implementers guide even requires to just ignore the IE (but act on the rest of the message). Note: If at least H.450.1 is supported by the B side, then B has to respond according to the "interpretation apdu" setting.
