Subject: Table 62B-1 10PASS-TS Test Cases

 

The group agreed to refer to test cases by the “old” (D2.0) test numbers for the duration of the call.

 

It was noted that the test cases fall into three groups:

 

Group 1: 1-9 basic tests (10/10 Mbps)

 

Group 2:  10-20 notching off

 

Group 3:  21-31 notching on

 

In general, Groups 2 and 3 are identical conditions, except for the presence of notching.

 

It was pointed out that some of the changes made in Ancona to Group 2 were not made to Group 3.  Since these changes involved reduction in reach, this makes the table inconsistent, as the presence of notching will not increase channel capacity.

 

Accordingly, the attendees agreed that it would be desirable to change #29 to 750m, # 25 to 650m and #23 from Self noise to AWGN.  There was not unanimous opinion to delete #22, as was done with #11 in Ancona.

 

However, there was general agreement that we would focus on Groups 1 & 3, and any changes made to Group 3 would be reflected in Group 2.

 

Sabina stated we should use ETSI A/F noise models when we use ETSI profiles

 

Vladimir took the assignment to supply more detailed specification for UPBO, especially for Self and AWGN noise models, prior to the next conference call.

 

One of the unsatisfied TR’s asks that simulation results or another method be presented in order to justify the numbers in the table.  In order to proceed with simulations, the assumptions must be agreed to.

 

Miguel suggested we start with Annex F of the ETSI standard [ETSI TS 101 270-1 V1.3.1 (2003-07)].  He took the assignment to come up with a proposal for assumptions for the group to use, based upon the ETSI document, prior to the next conference call.

 

Next conference call will be Thursday, 23-October, at 6 p.m. Geneva time (9 a.m. PDT).
