ITU-T P.340 compliance - - May 27 8:08:51 2009

hi all,

This is regarding compliance to ITU-T Rec. P.340.

As per p.340, Terminal coupling loss (TCLwst) is to be calculated after
normalizing the TCL for the values of RLR (receiver sensitivity rating) and SLR
(sending sensitivity rating).
If we plan to test the performance of the AEC software module (offline testing)
then how do we calcuate the TCL values.

What nominal values of RLR and SLR can be assumed?

Are there any known test suites for claiming compliance to ITU-T Rec. 
P.340 (or even IEEE 1329) ?
