Description

In the new test procedures, test case sMdl6 indicates the case where indexed = FALSE and RptEnabled max > 1 is prohibited, but I don’t see that in the standard.
In the case of association specific URCBs, having max=1 doesn’t indicate that each client has their own copy of the URCB available.

For an implementation that allows 7 clients where each can access one and only one copy of the URCB, RptEnabled max=7. According to Table 24 in -6, max is the number…which are instantiated at configuration time. We create 7 at configuration time, but they are not indexed. When a client connects it can enable its own copy.

Karen is correct.
The only standardized limitation is written in -6 for BRCB - Text below Table 24:
"In case of buffered control block indexed may only be set to false, if only one instance of this type is possible, i.e. max=1."

Note that only the ICT is allowed to create URCB ReportControl showing: index = false and RptEnabled max>1 as written in Table 23:
"the value false is not allowed for SCT creaetd instances".

I propose to change the second bullet of the test procedure sMdl6 from:
"An SCL Report Control with RptEnabled max > 1 and indexed=FALSE is prohibited". to
"An SCL Report Control with RptEnabled max > 1 and indexed=FALSE is prohibited for BRCB, and is only allowed for URCBs created by the ICT".
